Not a safer-sex lecture. This is the full modern picture: what U=U actually means in bed, PrEP for the partners who want it, mixed-status relationships, group sex and play parties without shame, kink and negotiation, doxycycline PEP for bacterial STIs, disclosure language you can borrow, conception, the law — and what all of it looks like in Florida.

Most HIV-and-sex material written in the last forty years was built to frighten people. It catalogued acts by danger and treated desire itself as the problem. If you are living with HIV, you have probably absorbed some of that — a small hesitation before the second date, a habit of reading your own body as a risk to someone else.

This page is written from the other direction. Sex is a good thing. HIV is a medical condition. Neither should erase the other, and the science of the last fifteen years made that a factual statement rather than a hopeful one. Four large studies followed thousands of couples across tens of thousands of condomless sex acts and did not document a single HIV transmission from a partner with a suppressed viral load.1234 That is the ground you are standing on.

Quick answer: U=U + PrEP + doxy-PEP is the toolkit that lets you have the sex life you actually want. Layered, not stacked as fear. A person living with HIV who takes antiretroviral therapy and keeps a viral load under 200 copies/mL will not transmit HIV to a sex partner.6 A partner who wants their own protection can take PrEP — daily pills, an injection every two months, or an injection every six months.89 And for bacterial STIs, doxycycline taken after sex cut syphilis and chlamydia by more than 70% in trials.10

Framing — the picture nobody handed you at diagnosis

Almost everyone diagnosed with HIV gets a version of the same conversation: labs, medication, follow-up appointment, and a brisk mention of telling partners. What almost nobody gets is a real conversation about sex — about pleasure, about dating, about the fact that a good sex life is a normal part of adult life and that HIV does not remove you from it. That silence leaves people to fill the gap with whatever they absorbed from the 1980s and 1990s, written before effective treatment existed. The honest modern summary: both the CDC's HIV clinical guidance and its STI treatment guidelines state plainly that people with HIV who achieve and maintain a viral load below 200 copies/mL have effectively no risk of sexually transmitting HIV.6

None of that is a mandate. Some people living with HIV want condomless sex with a long-term partner; some want condoms forever because condoms are simple; some want group sex, some monogamy, some a period of not dating at all. All complete answers. The science widens your options — it does not prescribe which one you pick. That is also why this page says mixed-status rather than serodiscordant.

U=U in practice — what it changes at 11 p.m. on a Saturday

Undetectable equals untransmittable is not a slogan bolted onto a hope. It is the plain-language summary of four large prospective studies, and the numbers are what turn belief into confidence.

Study 1 · 2011

HPTN 052 — the trial that changed the field

A randomized trial in 1,763 mixed-status couples across nine countries. Of 28 virologically linked HIV transmissions, only one was in the early-therapy group: a 96% reduction (hazard ratio 0.04).

Cohen MS et al., New England Journal of Medicine, 2011.1

Study 2 · 2016

PARTNER — condomless sex, observed, at scale

1,166 mixed-status couples in 14 European countries already having condomless sex while the partner living with HIV was suppressed — roughly 22,000 acts among male couples and 36,000 among heterosexual couples, zero phylogenetically linked transmissions. Eleven partners did acquire HIV; genetic analysis linked none of it to their partner.

Rodger AJ et al., JAMA, 2016.2

Study 3 · 2019

PARTNER2 — the anal sex question, answered

PARTNER's critics had a fair point: the condomless-anal-sex data was thinner. PARTNER2 closed that gap — 972 gay male couples, 76,088 condomless anal sex acts, zero linked transmissions, where roughly 472 would have been expected without treatment.5

Rodger AJ et al., The Lancet, 2019.3

Study 4 · 2018

Opposites Attract — outside Europe, outside the trial bubble

Male couples in Australia, Brazil, and Thailand: 343 couples, 16,800 condomless anal intercourse acts. In the 12,447 acts where the partner was suppressed and the other was not on daily PrEP: zero linked transmissions.

Bavinton BR et al., The Lancet HIV, 2018.4

These important findings unequivocally demonstrate that Undetectable=Untransmittable, or U=U — a concept that is integral to the four strategies of Ending the HIV Epidemic: A Plan for America. — Carl Dieffenbach, PhD, Director, Division of AIDS, National Institute of Allergy and Infectious Diseases, on the publication of PARTNER2.5

What "undetectable" has to mean before you rely on it

Under 200 copies/mL is the threshold. That is how the CDC defines viral suppression, and it is the number the transmission evidence is built on.6 A result of 60 copies is suppressed; a single blip to 300 in an otherwise stable history is a conversation with your provider, not an emergency. Durable matters more than momentary: NIAID describes durable suppression as staying undetectable for at least six months after your first undetectable result, and most people get there within six months of starting treatment.7 If you started medication three weeks ago, you are on your way.

Condoms after U=U — an actual choice now

U=U does not make condoms obsolete; it makes them optional for HIV purposes. Antiretroviral therapy does not protect against other sexually transmitted infections, and the CDC's STI treatment guidelines say so directly.6 Condoms still reduce chlamydia, gonorrhea, and syphilis, still prevent pregnancy, and for some people simply make sex feel less complicated. So the question shifts from "must I?" to "what do I want?" Condoms with new partners but not a regular one; for anal but not oral; none at all with quarterly screening plus doxy-PEP — all coherent plans. Our U=U page covers the science and the politics in full.

PrEP for partners — four ways to say yes to your own protection

Here is a thing that trips people up: if you are durably suppressed, your partner does not need PrEP to be protected from you. And plenty of partners want it anyway. That is not an insult. A partner might want PrEP because they have other partners, because they want protection that does not depend on someone else's pharmacy refill, or because the anxiety is real even when the math is settled. It lets a person hold their own prevention in their own hands.

The CDC's current clinical guidance covers four options.89

Option 1 · Daily pill

F/TDF — Truvada and generics

Emtricitabine 200 mg / tenofovir disoproxil fumarate 300 mg, one tablet daily. Approved for risk through sex and injection drug use, for anyone at least 77 lb (35 kg) with creatinine clearance above 60 mL/min. About 99% effective for sexual acquisition when taken consistently, and available as a generic.

CDC — Preexposure Prophylaxis clinical guidance.8

Option 2 · Daily pill

F/TAF — Descovy

Emtricitabine 200 mg / tenofovir alafenamide 25 mg, one tablet daily. Approved for sexual acquisition risk except receptive vaginal sex, because the trials did not enroll enough cisgender women. Usable down to creatinine clearance of 30 mL/min, so often chosen when kidney or bone health is a concern.

CDC — Preexposure Prophylaxis clinical guidance.8

Option 3 · Injection every 2 months

Cabotegravir — Apretude

600 mg intramuscular injection: a first dose, a second one month later, then every two months. Approved for all people at risk through sex, no kidney assessment required, greater than 99% effective for sexual acquisition. Six clinic visits a year instead of a daily pill — and nothing in a medicine cabinet for a roommate to find.

CDC — Preexposure Prophylaxis clinical guidance.8

Option 4 · Injection every 6 months

Lenacapavir — Yeztugo

FDA-approved on June 18, 2025 as the first twice-yearly HIV prevention option: a 927 mg subcutaneous injection plus oral tablets on days 1 and 2, then 927 mg every 26 weeks. PURPOSE 1 (cisgender women in sub-Saharan Africa) found zero infections among 2,134 participants; PURPOSE 2 found 2 among 2,179. The CDC issued a strong recommendation in September 2025. List price is roughly $28,218 a year, so patient assistance is part of the conversation.9

Adherence realities, honestly

PrEP works when it is in the body, and timing is not instantaneous. With daily oral PrEP, protection for receptive anal sex takes about seven days; for receptive vaginal sex and injection-related risk, up to about 21 days.8 A partner who starts PrEP on Friday is not protected by Saturday — and in a mixed-status couple with a suppressed partner, U=U is already doing the protective work.

On 2-1-1 — two pills 2 to 24 hours before sex, then one at 24 and 48 hours — the CDC is explicit: not FDA-approved, not CDC-recommended, and where used off-label, only for adult gay and bisexual men.8 European cohorts show people moving between schedules anyway: among 571 men who have sex with men in Belgian and Dutch PrEP programs, 31.7% switched regimens at least once.14 Flexibility is the norm — but it should be flexibility your prescriber knows about, alongside baseline and follow-up testing for HIV, chlamydia, gonorrhea, syphilis, hepatitis B, and kidney function.8 Full walkthrough on our PrEP page.

Mixed-status relationships — not a tragedy, a logistics problem you have already solved

Mixed-status couples used to be written about as if they lived in a controlled hazard zone. That framing is thirty years out of date; the daily reality is medication, appointments, and an ordinary life.

Mixed-status doesn't mean "careful" — it means you have more options than most couples. You have a suppressed viral load that reduces HIV transmission to effectively zero.6 You have four different PrEP formulations available to the partner who is HIV negative.8 You have condoms if you want them. You have doxy-PEP for bacterial STIs.10 And you have a body of evidence built specifically on couples like you — thousands of them, across four continents.234 Most couples make prevention decisions with far less information than you have.

Layering, not stacking

Layering is deciding that U=U covers HIV, PrEP gives your partner autonomy, and doxy-PEP covers bacterial STIs — three tools, three distinct jobs. Stacking is condoms plus PrEP plus avoidance of certain acts plus a persistent low-grade dread, all aimed at the same already-covered risk. Stacking keeps HIV at the center of a relationship long after the medicine moved it to the edges, and it can quietly tell the partner living with HIV that they are still regarded as dangerous. If your plan has more layers than jobs, that is worth a conversation — sometimes with a therapist rather than a prescriber. Couples where both partners live with HIV get almost no attention in prevention material: both still benefit from treatment for their own health, both still need STI screening, and superinfection with a second HIV strain, while documented, is rare.

The conversation to actually have

Four questions, revisited perhaps once a year rather than nightly:

Our HIV and relationships page goes further into the emotional side.

Group sex, play parties, saunas, cruising — no shame, real logistics

Group sex is common, it has been part of queer sexual culture for generations, and it is not a moral category. In a study of 357 gay, bisexual, and other men who have sex with men attending a Melbourne sexual health clinic, 32.2% reported group sex in the previous three months.13 That is roughly one in three people in a routine clinic waiting room.

Two findings there contradict the assumptions built into most prevention messaging. First, recent group sex was not associated with a same-day STI diagnosis in adjusted analyses. Second, living with HIV showed no association with group sex participation.13 People living with HIV are simply part of these spaces. A New York study of 211 men who had attended sex parties in the prior year adds nuance: men who were undetectable and men on PrEP both attended more parties and reported more anal sex partners than men using neither strategy — and had higher bacterial STI rates.13 The tools that made HIV manageable did not make gonorrhea manageable, which is exactly why doxy-PEP exists.

The Amsterdam AMPrEP cohort is reassuring on the point people worry about most. Across four years, bacterial STI incidence was high — 87 per 100 person-years — but it did not increase over time, and there were only two HIV acquisitions in four years.14 The feared spiral did not materialize.

Practical notes for group settings

A note on how this section is written. Group sex is treated as a logistics matter here because that is what the evidence supports.1314 If you have been told your sex life is the reason you got HIV, that was a judgment dressed as public health. You are allowed to keep your sex life.

A specific note on chemsex

Chemsex — the intentional use of drugs such as methamphetamine, GHB/GBL, or mephedrone to extend and intensify sex, often in group settings — is its own scenario with its own risks, and it is not a moral failing. The reasons to break it out are concrete. Sessions can run for hours or days, which changes tissue trauma, hydration, sleep, and eating. Antiretroviral and PrEP doses get missed, and adherence is the whole ballgame for both. GHB/GBL has a narrow margin between the dose that feels good and the dose that stops breathing. Injecting — "slamming" — introduces bloodborne HIV and hepatitis C risk that has nothing to do with sex. And consent capacity genuinely changes under sedatives and stimulants.

None of that requires you to stop. It requires a different plan: pre-loading medication doses before a session, deciding dosing intervals in advance, never sharing injecting equipment, and having one person who knows where you are. If chemsex has stopped being a choice you make and started being something that happens to you, that is worth naming without shame. Our HIV and substance use page covers harm reduction and treatment options in depth.

Kink and BDSM — negotiation as a prevention technology

Organized kink communities do something mainstream sexual culture mostly does not: they talk explicitly about what is going to happen before it happens — a practice built for physical and emotional safety that turns out to be a good vehicle for HIV and STI conversations too. The National Coalition for Sexual Freedom frames consent as explicit prior permission: you agree to specific acts and their intensity beforehand, you have a way to stop at any time, and you are of sound mind. Its negotiation guidance also says participants should negotiate protection against pregnancy and sexually transmitted infections, and that someone too intoxicated to understand the consequences cannot legally consent.20

If you live with HIV, that structure is a gift. Status, viral load, PrEP, condom preferences, and barrier plans all fit naturally into a pre-scene negotiation, at a moment when everyone is clothed, sober, and expecting to discuss logistics.

Blood, needles, and cutting

Most kink involves no HIV risk at all — impact play, bondage, rope, sensation play, and power exchange do not transmit HIV. What needs attention is blood and broken skin: needle play, cutting, scarification, cupping that draws blood.

The relevant numbers come from the transmission-risk literature rather than from kink research: a percutaneous needle stick from a source with untreated HIV carries an estimated risk of about 23 per 10,000 exposures, and needle-sharing about 63 per 10,000.11 Those figures describe unsuppressed HIV. Hepatitis C is the more transmissible bloodborne virus here and often the more realistic concern.

Practical harm reduction for blood play:

Aftercare and kink-affirming care

Aftercare — the deliberate period of settling after intense play — is where a lot of health conversation actually lands, because that is when people are honest: a reasonable time to check in about anything that bled and whether anyone needs testing. Finding a clinician who will not pathologize your sex life is a separate task, and NCSF's Kink Aware Professionals directory lists providers who volunteered to be contacted by people involved in kink, leather, BDSM, fetish, and polyamory communities.20 An HIV clinician who treats your kink as a diagnosis will be a poor partner in the rest of your care too.

Anal sex — anatomy, roles, and how the tools stack up

Anal sex carries the highest per-act HIV transmission probability of any sexual activity, and understanding why makes the prevention logic obvious rather than frightening. The rectal lining is a single layer of columnar epithelium — thin, absorptive by design, rich in the immune cells HIV targets — over a dense blood supply. A structural difference, not a behavioral one.

The per-act estimates from the CDC's systematic review, all assuming no condom use and an untreated source:11

Read those as a ratio: receptive anal sex carries roughly twelve times the per-act probability of insertive anal sex and seventeen times that of receptive vaginal sex — the entire reason "bottoming" appears so often in prevention material. Now layer the tools on. Consistent condom use reduced HIV incidence about 80% in the same review, and condoms plus antiretroviral treatment of the partner living with HIV attenuated risk by 99.2%.11 PARTNER2 went further: 76,088 condomless anal sex acts with a suppressed partner, zero linked transmissions.3 The highest-probability act, with the most effective tool applied, produced none.

Comfort is tissue care, not modesty: anal sex that hurts is anal sex that tears, and small tears matter for bacterial STIs and hepatitis C even in a U=U context. Use generous water- or silicone-based lubricant, stop when something hurts, remember that oil degrades latex condoms and silicone degrades silicone toys, and douche gently if you douche at all.

HPV and anal cancer screening — the part people skip

This is the most under-discussed piece of anal health for people living with HIV, and it has nothing to do with transmitting HIV. HPV-related anal cancer is substantially more common among people living with HIV, and 2024 brought the first comprehensive screening guidelines: the International Anal Neoplasia Society recommends starting at age 35 for men who have sex with men and transgender women living with HIV, and age 45 for other people living with HIV.19 The federal opportunistic infections guidelines agree, and add annual assessment of anal symptoms — unexplained itching, bleeding, pain, or perianal lesions — for everyone living with HIV. Screening is usually an anal Pap, high-risk HPV testing, or both, with high-resolution anoscopy if results are abnormal.19 HPV vaccination is recommended too. Ask about both at your next visit.

Oral sex — very low HIV risk, real STI risk

Oral sex is where the HIV messaging of the 1990s did the most unnecessary damage. The current CDC position is that oral sex carries little to no risk of HIV transmission, and that HIV is not transmitted through saliva.12 The systematic review could not generate a numeric point estimate at all, because no transmissions were observed across 8,965 receptive oral sex acts studied.11 The CDC does note factors that raise the small chance: ejaculation into the mouth, oral ulcers, bleeding gums, genital sores, or other sexually transmitted infections.12 Add a suppressed viral load and the residual figure becomes a rounding error.

Bacterial and viral STIs are a different story. Gonorrhea, chlamydia, syphilis, herpes, and HPV all spread this way, and the CDC notes that in a study of gay men diagnosed with syphilis, one in five reported having had only oral sex. Pharyngeal gonorrhea is frequently asymptomatic — a major reason throat swabs belong in routine screening. If you want barriers, use a condom for oral sex on a penis and a dental dam or a condom cut open lengthwise for a vulva or anus.12 Plenty of people decline barriers and rely on regular site-specific screening instead — a reasonable choice that works far better when the screening includes the throat.

Vaginal sex — biology, U=U, PrEP, and internal condoms

Vaginal sex gets less attention in HIV prevention material than it should, partly because so much research has centered on men who have sex with men. The vaginal and cervical lining is stratified squamous epithelium — thicker and more layered than rectal tissue, which is why the per-act probability is lower: 8 per 10,000 exposures for receptive penile–vaginal intercourse and 4 per 10,000 for insertive, without condoms and with an untreated source.11 Other genital infections, bacterial vaginosis, cervical inflammation, menstruation, and the higher viral loads of acute infection all shift that number upward, and tissue changes around menopause can increase friability — reasons to treat genital infections promptly and use enough lubricant, not reasons to avoid vaginal sex.

U=U applies fully here. PARTNER included roughly 36,000 condomless acts among heterosexual couples with a suppressed partner and documented no linked transmissions.2 HPTN 052, largely heterosexual couples, produced the 96% reduction that opened the door to all of this.1

Two practical notes specific to vaginal sex:

STIs and doxy-PEP — 200 mg, within 72 hours

In June 2024 the CDC published clinical guidelines on doxycycline as post-exposure prophylaxis for bacterial STIs — the first genuinely new bacterial STI prevention tool in decades.10 The regimen is simple: doxycycline 200 mg, taken once by mouth as soon as possible after oral, vaginal, or anal sex, and within 72 hours, not exceeding 200 mg in any 24-hour period.10

Doxy-PEP decision box. Ask your clinician about doxy-PEP if you are a gay or bisexual man, another man who has sex with men, or a transgender woman, and you have had at least one bacterial STI — syphilis, chlamydia, or gonorrhea — in the past 12 months. That is the CDC's recommended population, arrived at through shared decision-making, and it is rated AI: a strong recommendation backed by high-quality evidence.10

What you get: across three randomized trials, doxy-PEP reduced syphilis and chlamydia by more than 70% and gonococcal infections by roughly 50%.10 In the U.S. DoxyPEP trial the number needed to treat to prevent one STI was 4.7 among participants on PrEP and 5.3 among participants living with HIV.10

What you take on: photosensitivity, esophagitis, gastrointestinal upset, microbiome effects, possible antimicrobial resistance, and unknown long-term effects.10 Take it on a full stomach with a full glass of liquid, stay upright for an hour, and separate it by two hours from dairy, antacids, calcium, iron, magnesium, and sodium bicarbonate. No clinically relevant interaction with gender-affirming hormone therapy is expected.10

Ongoing: site-specific NAAT testing plus syphilis serology every 3 to 6 months, with the need for doxy-PEP reassessed at the same interval.10

The gap: cisgender women, and why it matters

The guidance is explicit that no recommendation can be given at this time for cisgender women, cisgender heterosexual men, transgender men, or other queer and nonbinary people assigned female at birth, because clinical data are limited.10 In practical terms: doxy-PEP is not currently recommended for cisgender women whose partners are penetrating them vaginally, and there is no approved analogue for them.

The evidence behind that gap is a single trial: 449 cisgender women in Kenya, 2020 to 2022, which found no significant reduction in bacterial STIs. The critical detail is that doxycycline was detected in the hair of only 29% of participants in the doxycycline arm, and the CDC notes nonadherence may well explain the null result, while acknowledging that cervicovaginal drug concentrations still need exploring.10

That is a research gap, not a biological verdict — the same pattern that recurs throughout HIV prevention research, where trials in women arrive later and smaller. If you are a woman living with HIV or dating someone who is, it is fair to name this gap with your provider. Community publications such as POZ and TheBody have covered the frustration from a community perspective.

Disclosure — language you can borrow, timing you choose

There is no correct moment to tell someone you are living with HIV. Early disclosure filters out people who would reject you before you are invested — and hands your health information to strangers. Later disclosure protects your privacy and builds a connection first — and can feel to the other person like something was withheld. Both are defensible. What helps is having language ready, so you are not composing under pressure.

On dating apps

In profile, if you want it there: "Poz, undetectable, on treatment — which means I can't pass HIV on. Happy to answer questions."

In a chat, once there is interest: "Before we meet — I'm living with HIV. I'm on treatment and undetectable, so I can't transmit it. That's not a maybe; it's what four big studies of thousands of couples found. Ask me anything you want."

Before first sex

Clothed, sober, not in the doorway: "I want to tell you something before this goes further, because I want you to have real information and not a surprise. I'm living with HIV. I've been on treatment for [time] and my viral load is undetectable, which means I can't pass it to you. If you want to look it up, the search term is U=U. If you'd feel better also being on PrEP, I'm completely fine with that — it's your body."

That last sentence does a lot of work: it removes the implication that wanting PrEP is an accusation, and gives the other person something active to do with their anxiety.

In the moment, when the moment moved faster than you did

There is no elegant version: "Hang on — I need to say something. I'm living with HIV, I'm undetectable, and I can't pass it on. I should have said it earlier. Do you want to keep going, or stop and talk?" Offering the stop is what makes it a disclosure rather than an announcement.

When it goes badly

Sometimes people react with fear, or cruelty, or they simply disappear. That is about the education they were given, not your worth — and it will still hurt. What helps: tell people when you have the emotional room to absorb a bad response, and have someone you can text afterward. Our stigma and disclosure page goes deeper, and our mental health and HIV page has options if this is producing real distress.

One important caveat. In some U.S. states, disclosure is not only an interpersonal question — it is a legal one, and the law may not care whether you are undetectable. Read the criminalization and Florida sections before you decide your approach, particularly if you live in a state with an HIV-specific criminal statute.

Conception — building a family, with the science on your side

For most of the epidemic, a mixed-status couple who wanted a biological child was routed into sperm washing, intrauterine insemination, or IVF — expensive, clinical, often out of reach. That is no longer the default, and it is one of the clearest wins of the U=U era. The federal perinatal HIV guidelines now state it directly: for partners with different HIV status, when the person with HIV is on antiretroviral therapy and has achieved sustained viral suppression, sexual intercourse without a condom allows conception without sexual HIV transmission to the partner who is HIV negative.15

What the guidelines recommend before you start trying

Pregnancy and perinatal transmission

When fully suppressive antiretroviral therapy is started before pregnancy and an undetectable viral load is maintained through delivery, the risk of perinatal HIV transmission is under 1%, and scheduled cesarean delivery solely to prevent transmission is not routinely recommended when HIV RNA is at or below 1,000 copies/mL.15

Sperm washing and IVF have not vanished; they have stopped being mandatory, and remain the right path when there is a fertility issue, when suppression cannot be sustained, or when a partner prefers a non-sexual route. For the full pathway, see our HIV and pregnancy planning page.

Criminalization — where the law has not caught up with the science

The law in much of the United States does not reflect anything you have read above. The Center for HIV Law and Policy, which maintains the most detailed mapping of these statutes, reports that 32 states criminalize people living with HIV and that 28 states have harsh criminal penalty enhancements that elevate charges based on a person's knowledge of their HIV status.16 Their maps note something instructive: North Dakota and Maryland fully repealed their HIV-specific exposure offenses, yet the count of 32 did not fall, because both retained health-code provisions that still reach people living with HIV. Repeal of the headline statute is not the same as decriminalization.

The CDC, counting somewhat differently, reports that 34 states criminalize actions by people with HIV through HIV-specific or STD-specific laws, and that 14 states criminalize behaviors with negligible or low transmission risk — including spitting, biting, and oral sex.17 The CDC's own assessment is blunt: most of these laws do not reflect current scientific and medical evidence, states should consider updating or repealing them, and they have not increased disclosure while they may discourage testing and increase stigma.

The Sero Project, which organizes people living with HIV against criminalization, describes three routes by which prosecutions happen: HIV-specific laws where transmission is not required for a conviction; general criminal codes covering infectious disease; and sentence enhancements attached to other offenses. In its 2021 National HIV Criminalization Survey, 55.2% of respondents lived in a state with an HIV-specific criminalization law, and Sero documents at least 104 prosecutions between 2013 and 2015 alone.18 The Center for HIV Law and Policy's Sourcebook covers all fifty states plus the military, federal prisons, and U.S. territories.16

The specific mismatch with U=U

Most of these statutes turn on disclosure and consent. They do not turn on viral suppression, condom use, or whether transmission actually occurred. Which produces the situation people find hardest to believe: a person who is durably undetectable, who cannot transmit HIV, can still be prosecuted for not disclosing. Some states have amended their laws to account for viral suppression or condom use; many have not. Where you live changes what disclosure means for you legally — and that is not information most people receive at diagnosis.

What to actually do. Look up your own state's law before you decide how you handle disclosure — the Center for HIV Law and Policy's mapping resources and its Sourcebook are the most complete public references.16 If you are facing an accusation or a charge, contact an attorney with HIV criminalization experience before speaking to anyone — the Sero Project maintains resources for people in that position. Nothing on this page is legal advice. Our HIV criminalization page covers the landscape in detail.

Florida — the statute, the penalties, and where to get what you need

Florida matters here for two reasons: it carries one of the heaviest HIV burdens in the country, and it has one of the oldest and most explicit HIV-specific criminal statutes. On burden, in 2024 the South had the highest regional HIV diagnosis rate in the United States at 17.7 per 100,000 compared with 13.3 nationally, and Florida's HIV-related death rate of 2.8 per 100,000 placed it among the highest of any state.21 Those numbers are about access to care, insurance, transportation, stigma, and how long people go undiagnosed — not individual behavior.

Florida Statute 384.24 — what it actually says

Florida Statute 384.24 has two subsections. Subsection (1) makes it unlawful for a person with any of a list of sexually transmissible diseases — among them gonorrhea, genital herpes simplex, chlamydia, and syphilis — who knows they have it and has been informed it may be communicated through sexual intercourse, to have sexual intercourse with another person unless that person has been informed and has consented. Subsection (2) applies the same structure to HIV.22

The penalties are in Florida Statute 384.34. A violation of 384.24(1) — the other STIs — is a first-degree misdemeanor. A violation of 384.24(2), the HIV subsection, is a third-degree felony, and multiple violations a first-degree felony.22 That is the sentence-enhancement pattern the Center for HIV Law and Policy documents nationally, written into Florida law: the same conduct is a misdemeanor for chlamydia and a felony for HIV.

Read the statute carefully for what is not in it. Florida Statute 384.24(2) turns on knowing your status, having been informed HIV can be communicated through sexual intercourse, and whether your partner was informed and consented.22 It does not turn on your viral load, condom use, or whether transmission occurred. A person who is durably undetectable and cannot transmit HIV — a fact the CDC states plainly6 — is not exempted by the text of the statute. Florida was also one of the three original states to enact HIV-specific criminal law in 1986. If you live in Florida, know this before you decide your disclosure approach, and talk to an attorney rather than the internet if anything is already in motion. Our Florida HIV criminalization page goes into the detail.

Getting PrEP, PEP, and doxy-PEP in Florida

The Florida Department of Health's standing guidance for anyone who thinks they have been exposed to HIV is to contact a hospital emergency room, urgent care clinic, or county health department for PEP evaluation. PEP is time-sensitive — start as soon as possible, and it is not useful after 72 hours. Doxy-PEP is available county by county rather than uniformly: the CDC's national prevention services directory lists Doxy PEP among the clinical services at the Florida Department of Health in Pinellas County's Mid-County Health Department in Largo.21 If your county does not offer it, Ryan White clinics, federally qualified health centers, and LGBTQ+ health centers are the next places to ask.

Florida's sexually open communities

Florida has long-established sexually open and queer communities — Wilton Manors and Fort Lauderdale, South Beach and greater Miami, Key West, the Tampa Bay corridor — with bathhouses, leather and kink events, and circuit and pride weekends. Those communities also built the HIV service organizations around them, many running their own testing, PrEP navigation, and STI screening. That is the practical Florida picture: strong community infrastructure in the metros, thinner coverage in rural counties, and a felony statute that applies statewide regardless. Use our find care page to locate services, and see HIV in rural Florida if you are outside the metro corridors.

What to do next

If you take one thing from this page: the tools now exist to have the sex life you actually want — not a permitted version, not a reduced version. The work is mostly logistical.

  1. Know your viral load and how long it has been suppressed. Under 200 copies/mL is the threshold,6 and durable means at least six months past your first undetectable result.7 If you do not know the number, that is the first phone call.
  2. Bring PrEP into the conversation with partners who want it. Four formulations exist, from a daily generic pill to a twice-yearly injection.89 It is their choice, not a referendum on you.
  3. Ask about doxy-PEP if you meet the criteria — a man who has sex with men or a transgender woman with a bacterial STI in the past year. If you do not meet them, ask anyway; shared decision-making is part of the guidance. Get screened every 3 to 6 months if you have multiple partners, with site-specific testing including throat and rectum plus syphilis serology, and catch up on mpox, hepatitis A, hepatitis B, and HPV vaccination.10
  4. Ask about anal cancer screening. Age 35 for men who have sex with men and transgender women living with HIV; age 45 for other people living with HIV.19
  5. Look up your state's HIV criminalization law. Thirty-two states criminalize people living with HIV, and most statutes ignore viral suppression entirely.1622
  6. Write one disclosure sentence you can say out loud, and practice it once. The first time should not be improvised.
  7. Find a clinician who does not flinch. Ryan White clinics, community health centers, and LGBTQ+ health centers tend to handle sex, kink, and drug use without moralizing — and NCSF's Kink Aware Professionals directory exists for the harder searches.20

The bottom line. Four large studies covering more than 100,000 condomless sex acts found zero HIV transmissions from partners with a suppressed viral load.1234 PrEP gives partners who want their own protection four ways to have it.8 Doxycycline after sex cut syphilis and chlamydia by more than 70% in randomized trials.10 The remaining obstacles are mostly not medical — they are laws written in the 1980s, a research gap for cisgender women, and the leftover feeling that you are supposed to apologize for wanting sex. You are not.

  12. CDC — How HIV Spreads. States that oral sex carries little to no risk of HIV transmission, that HIV is not transmitted through saliva, and identifies factors that can increase the small chance (ejaculation in the mouth, oral ulcers, bleeding gums, genital sores, other STIs). The CDC's STI Risk and Oral Sex page documents STI transmission through oral sex, the finding that one in five gay men in a syphilis study reported only oral sex, and barrier options including condoms, dental dams, and cut-open condoms.

Published February 2025, map set updated November 12, 2025: 32 states criminalize people living with HIV and 28 states have harsh criminal penalty enhancements based on knowledge of HIV status; North Dakota and Maryland became the fourth and fifth states to fully repeal HIV-specific exposure offenses without changing the count of 32, because both retain communicable-disease health-code provisions. State-by-state detail, including sentence enhancements, confidentiality exceptions, sex offender registration, and punitive STI provisions across all 50 states, the military, federal prisons, and U.S. territories, is in CHLP's HIV Criminalization in the United States: A Sourcebook, 3rd edition, updated January 2024.
  17. CDC — HIV Criminalization and Ending the HIV Epidemic. Reports that 34 states criminalize actions by people with HIV through HIV-specific or STD-specific laws and that 14 states criminalize behaviors with negligible or low transmission risk including spitting, biting, and oral sex; states that most HIV criminalization laws do not reflect current scientific and medical evidence, that states should consider updating or repealing them, and that these laws have not increased disclosure while they may discourage testing, increase stigma, and exacerbate disparities.
  18. Sero Project — National HIV Criminalization Survey Report, 2021 (PDF). Describes the three legal routes by which people living with HIV are prosecuted — HIV-specific laws not requiring transmission, general criminal codes covering broader infectious diseases, and sentence enhancements — and reports that 55.2% of respondents lived in a state with an HIV-specific criminalization law. Sero's HIV criminalization research page documents at least 104 U.S. prosecutions between 2013 and 2015. Global figures — 156 countries criminalizing HIV non-disclosure, exposure, or transmission or with prosecutions in the past decade in 2024, including 86 with HIV-specific criminal laws and 45 with broader communicable-disease laws — are from UNAIDS, HIV and Human Rights: Criminalization fact sheet (PDF).

Community consent guidance including the reminder to negotiate protection against pregnancy and sexually transmitted diseases and the statement that a person too intoxicated or otherwise unable to understand the consequences of sex or kink cannot legally consent. NCSF's Kink Booklet sets out the Explicit Prior Permission framework — agreement to specific acts and their intensity before starting, agreement on what roleplay resistance may be ignored, a safeword or safe signal, soundness of mind, and no risk of serious injury — and its resources page hosts the Kink Aware Professionals directory.
  21. CDC — HIV Diagnoses, Deaths, and Prevalence (2024 data). In 2024 there were 38,793 HIV diagnoses in the United States and 7 territories and freely associated states; the national diagnosis rate was 13.3 per 100,000 and the South's was 17.7; Florida's HIV-related death rate of 2.8 per 100,000 was among the highest of any state. Florida-specific service guidance is on the Florida Department of Health PrEP & PEP page, which directs people seeking PEP to a hospital emergency room, urgent care clinic, or county health department; doxy-PEP among county health department clinical services is listed in the CDC National Prevention Information Network entry for the Florida Department of Health in Pinellas County, Mid-County Health Department.
  22. Florida Statutes § 384.24 — Unlawful acts. Subsection (1) covers chancroid, gonorrhea, granuloma inguinale, lymphogranuloma venereum, genital herpes simplex, chlamydia, nongonococcal urethritis, pelvic inflammatory disease/acute salpingitis, and syphilis; subsection (2) applies the same disclosure-and-consent structure to human immunodeficiency virus infection. Penalties are in Florida Statutes § 384.34: a violation of § 384.24(1) is a first-degree misdemeanor, a violation of § 384.24(2) is a third-degree felony, and multiple violations of § 384.24(2) constitute a first-degree felony. Neither section conditions liability on viral load, condom use, or actual transmission.
