Safer Sex for LGBTQ+ People: STIs, Barriers, PrEP & PEP

• HIV risk varies hugely by practice — receptive anal sex carries the highest per-act risk, oral sex the lowest. Effective treatment (U=U) and PrEP can reduce risk to near zero.
• Most STIs are silent. Gonorrhoea and chlamydia at the throat and rectum are usually symptom-free, so site-specific screening (not just a urine test) matters.
• Barriers are practice-specific: external/internal condoms for penetration, dental dams (or a cut-open condom) for oral-vulva and oral-anal sex, condoms on shared toys, gloves for manual sex.
• PrEP prevents HIV before exposure and is free for key populations through NACO; PEP is a 28-day course that must start within 72 hours (ideally 2 hours) of a possible exposure.
• The myth that women who have sex with women can't get STIs is wrong and has caused real under-screening. HPV, herpes, BV and more do transmit between vulvas.
• Affirming STI testing exists in India through NACO clinics and queer-led organisations like Humsafar Trust and Naz Foundation, alongside private labs.

Targeting safer sex starts with knowing the transmission routes for the sex you actually have. Risk depends on the practice, your partner's HIV/STI status, barrier use and your own risk factors — not on your identity label.

HIV risk varies enormously by act. Per CDC and WHO estimates, receptive anal sex (being the receiving partner) carries the highest per-act risk of common practices — roughly 138 transmissions per 10,000 exposures with an untreated HIV-positive partner — because the rectal lining is thin, easily torn and rich in the immune cells HIV targets. Insertive anal sex is lower (around 11 per 10,000), receptive vaginal sex around 8, insertive vaginal around 4. Oral sex risk is much lower (well under 1 per 10,000) and manual sex without blood contact is very low. Crucially, all of these drop to near zero when the HIV-positive partner is on treatment with an undetectable viral load (U=U) or when the HIV-negative partner is on PrEP. For the full picture see our guide to real per-act transmission risks.

Syphilis spreads through contact with sores (chancres or mucous patches), which can sit in the genital, anal or oral area and aren't always visible. Condoms only help where they cover the sore. It is highly curable with benzathine penicillin, but untreated late syphilis is serious — and rates are rising in India, including in queer communities.

Gonorrhoea and chlamydia infect whatever mucous membrane they contact — genitals, rectum or throat. Throat and rectal infections are very often silent, so they are detected by screening, not symptoms. Untreated, they can cause pelvic inflammatory disease, epididymitis and fertility problems. Both are treatable, though gonorrhoea's growing antibiotic resistance is a real concern.

Herpes (HSV) passes through skin-to-skin contact with the affected area, even with no visible sore, because the virus sheds silently. Oral sex can transmit HSV-1 from a mouth to a partner's genitals — yes, you can get herpes even without a visible outbreak. It's lifelong but well managed with antivirals.

HPV spreads through skin-to-skin genital contact, with or without penetration, and condoms reduce but don't eliminate it. Some strains cause genital warts, others cause cervical, anal, throat and other cancers. Vaccination is the key prevention tool; in India, Cervavac (approved 2022) and Gardasil are both available. Vaccination is routinely recommended through age 26 and may help through 45 based on risk.

Hepatitis B transmits through blood and sexual fluids, especially in condomless anal sex, and is vaccine-preventable. Hepatitis C is mainly blood-borne (shared needles) with lower sexual transmission, has no vaccine, but is now curable with direct-acting antivirals. Trichomoniasis and Mycoplasma genitalium are less-discussed but real, the latter complicated by antibiotic resistance.

Finally, bacterial vaginosis and yeast infections aren't classic STIs, but vaginal flora can shift between partners — recurrent BV is more common in women who have sex with women in some studies.

No single barrier covers every practice, so it helps to match the method to the act.

External condoms (worn on a penis, dildo or other phallic object) block HIV, syphilis, gonorrhoea, chlamydia and hepatitis B over the area they cover, and reduce — but can't fully prevent — HSV and HPV. Choose latex, or polyurethane/polyisoprene for latex allergy. Avoid lambskin: its pores stop sperm but not viruses, so it prevents pregnancy only, never STIs. Use a new one for every act and partner, add water- or silicone-based lube to prevent breakage, and never double up — two condoms create friction and tear. Our guide on how effective condoms really are covers correct use and failure rates, and storing them right matters in India's heat. Indian brands include Manforce, Skore, KamaSutra, Durex, Moods and the free government Nirodh supply; fit matters more than people think.

Internal condoms (inserted into the vagina or anus) can go in before sex, don't need an erection and suit people who prefer not to use external condoms. Indian availability is limited but growing.

Dental dams are latex squares used as a barrier for oral sex on a vulva or anus, blocking HSV, HPV, gonorrhoea and syphilis. They're hard to find in Indian retail, so queer communities use long-standing workarounds: cut an external condom lengthwise into a flat sheet, or use non-microwavable cling film. Our guide on dental dams and flavoured condoms for oral sex explains the technique; organisations like Naz Foundation and Humsafar Trust sometimes distribute dams.

Gloves and finger cots protect during manual sex, especially with cuts, hangnails or when moving between partners. Short clean nails and hand-washing help regardless. Condoms on shared sex toys (changed between partners) stop infection passing between people sharing toys.

Lube choice affects safety. Water-based lube works with everything; silicone-based works with condoms but degrades silicone toys; oil-based (including coconut oil and petroleum jelly) degrades latex condoms and must be avoided with them. Skip lubes with glycerin, warming/cooling additives or numbing agents, which can irritate or mask injury. Our evidence-based guide to choosing lube goes deeper. Some couples move to 'fluid bonding' — dropping barriers after mutual testing within a committed arrangement — which depends entirely on trust, communication and consistent practice.

Biomedical prevention has reshaped HIV risk over the last decade and now sits alongside — sometimes instead of — barriers.

PrEP (pre-exposure prophylaxis) is medication taken before exposure to stop HIV taking hold. The standard regimen is daily tenofovir/emtricitabine (Truvada or generics), with tenofovir alafenamide (Descovy) as an alternative; injectable cabotegravir exists globally but has limited Indian availability. Taken consistently, oral PrEP is about 99% effective against sexual HIV transmission. NACO has integrated PrEP into the national programme since 2017 and provides it free to key populations (MSM, transgender people, sex workers, people who inject drugs) through Targeted Intervention programmes and ART centres. Privately, Indian generics typically cost ₹600–1,500 a month. Before starting, you need an HIV test (you must be negative), kidney and hepatitis B checks, then follow-up every three months. For a deeper India walk-through, see PrEP for HIV prevention. 'On-demand' or 2-1-1 dosing is an option for some men who have sex with men, but daily PrEP remains the best-supported regimen.

PEP (post-exposure prophylaxis) is a 28-day, three-drug course taken after a possible exposure — condom breakage with a partner of unknown or positive status, sexual assault, a needlestick. It must start as soon as possible, ideally within 2 hours and certainly within 72 hours; after that it is generally not recommended. Access PEP through hospital emergency departments and NACO ART centres. Finishing the full course matters, with HIV testing at 4–6 weeks, 3 months and 6 months afterwards.

U=U (Undetectable = Untransmittable) is the principle, backed by the PARTNER and Opposites Attract studies and endorsed by WHO and CDC, that a person on consistent HIV treatment with a sustained undetectable viral load cannot pass HIV on sexually. It has transformed serodiscordant relationships and reduced stigma — and people with HIV today have near-normal life expectancy. For broader context, see HIV prevention, testing and treatment for women in India.

Screening is the heart of safer sex because so many infections are silent. Catching them early protects your fertility, lowers HIV susceptibility and stops onward transmission.

General screening guidance for sexually active LGBTQ+ people:

• HIV: at least yearly; every 3–6 months with multiple partners or higher risk; quarterly on PrEP; after any specific exposure.
• Syphilis: at least yearly; every 3–6 months if higher risk.
• Gonorrhoea and chlamydia: at least yearly; every 3–6 months if higher risk — and test at every site of contact. Throat swabs catch oral infections, rectal swabs catch infections from receptive anal sex. A urine test alone misses most of these.
• Hepatitis B: screen and vaccinate if not immune. Hepatitis C: at least one-time screening.
• HPV/cervical screening: anyone with a cervix needs age-appropriate cervical screening — the myth that lesbian and queer women can skip their Pap smear is wrong and dangerous. Trans masculine people with a retained cervix follow the same guidance. Anal Pap smears are recommended for some higher-risk groups, such as HIV-positive MSM and trans women.

Toys play a meaningful role in many queer sexual lives, and a little hygiene goes a long way.

Material matters. Non-porous, body-safe materials — medical-grade silicone, glass, stainless steel, ceramic — can be cleaned thoroughly and sometimes sterilised. Porous materials (jelly, PVC, TPE, rubber) trap bacteria even after washing, so they're a poorer choice for ongoing use.

Clean between uses: rinse with warm water, wash with mild unscented soap, rinse and dry. Non-electronic silicone toys can be boiled for 3–5 minutes or run through a dishwasher (top rack, no detergent). For toys with electronics, wipe around the components without submerging them.

Sharing toys: put a condom over the toy and change it between partners, clean thoroughly, or keep separate toys per person. Without this, toys can pass BV-related bacteria, herpes, HPV, gonorrhoea and chlamydia between people.

Anal toys must have a flared base to prevent migration into the rectum, which can need emergency removal. Use generous water- or silicone-based lube, and clean thoroughly before using a toy elsewhere — moving anal bacteria to the vagina or urethra can cause infections. For more, see our practical guide to whether anal sex is safe.

Lube and storage: water-based lube suits all materials; silicone lube degrades silicone toys (a common surprise); oil-based degrades some materials. Store toys clean, dry and ideally separated. Replace any toy that cracks, tears or degrades. In India, toys are increasingly available through online retailers (Amazon India, IMBesharam, MyMuse, Thatspersonal) with discreet packaging — choosing established body-safe silicone brands is worth the small extra cost.

Honest conversation is a safer-sex skill that gets easier with practice. It's also where safer sex and consent meet.

Talk about STI status before sex, ideally. Simple openers work: 'When were you last tested, and for what?' or 'I was tested on [date]; here are my results — how about you?' If you live with HSV, HIV or another infection, honest disclosure is both ethical and, for HIV in some Indian contexts, legally relevant.

Talk about barriers before things start: which acts you want to use condoms or dams for, and whether your partner is on the same page. Preferences can differ and that's fine to negotiate — but pressuring someone to drop a barrier is sexual coercion, not consent. Quietly removing a condom without agreement is stealthing, a recognised consent violation.

Talk about PrEP and PEP: 'I'm on PrEP', 'Are you?', 'Where would we get PEP if a condom fails?' In serodiscordant couples, conversations about treatment, viral load and U=U are central — many such partnerships are safe and thriving with these tools.

Consent stays the foundation. It must be informed, freely given, specific to each act, and ongoing — withdrawable at any moment. Discussing STI status and barriers is part of informed consent. For non-monogamous or polyamorous setups, explicit safer-sex agreements (testing schedules, barrier rules, what happens if an STI shows up) keep everyone protected.

If a partner refuses safer sex you're comfortable with, walking away is a valid, healthy response. And if a consent violation or assault has happened, seek care regardless of whether you report: PEP if HIV exposure is possible, STI testing, and emotional support. If you need help with next steps, our guide on what to do after being touched without consent points to support, including queer-affirming counsellors.

Knowing the landscape makes it far easier to get affirming care.

NACO runs the National AIDS Control Programme: HIV testing through ICTCs, treatment through ART centres, free PrEP and PEP for key populations, free Nirodh condoms, and Targeted Intervention (TI) programmes for MSM, transgender people, sex workers and people who inject drugs. Affirmation varies — TI programmes designed for these communities tend to be more welcoming than general clinics. Community referrals help you find the good ones.

Queer health organisations provide services and referrals: Humsafar Trust (Mumbai, helpline 022-26673800), Naz Foundation (Delhi), Mitr Trust (Delhi, trans-focused), Sahodaran (Chennai), Solidarity Foundation (Bengaluru) and Garima Greh shelters. Most maintain networks of affirming providers in their regions. For the mental-health side of all this, see LGBTQ mental health in India.

Private STI testing runs through Dr Lal PathLabs, SRL, Metropolis, Thyrocare and Apollo (panels typically ₹2,000–5,000, usually needing a prescription). Public-sector testing through Suraksha Clinics is minimal or free.

Barrier access: dental dams remain a gap — use online retailers, queer organisations, or the cut-condom and cling-film workarounds above. Emergency contraception (where pregnancy is a concern) is widely available over the counter as the i-pill and similar LNG products; a copper IUD within five days is the most effective option.

Mental-health and crisis support: QACP-trained queer-affirming therapists, iCall (9152987821) and the Vandrevala Foundation (1860-2662-345). Legal context: the post-Navtej Singh Johar (2018) landscape decriminalised consensual same-sex relations, with the Transgender Persons (Protection of Rights) Act 2019 adding protections. Affirming legal help is available through organisations like the Lawyers Collective. Building a relationship with an affirming provider, once you find one, pays off over years of better care.
