Safer sex basics, plainly explained

Safer sex is risk reduction, not risk elimination. Nothing — including abstinence — eliminates all risk; the question is which tradeoffs you and your partners actually want. Knowing the real options makes both choices and conversations easier.

Barriers

• External (penile) condoms reduce most STI transmission and pregnancy risk substantially when used consistently. Latex is the default; polyurethane and polyisoprene exist for latex allergies. Lambskin condoms do NOT protect against STIs.
• Internal ("female") condoms line the vagina or anus; they can be inserted ahead of time and are a good option for receptive partners.
• Dental dams are thin latex or polyurethane squares used for oral sex on a vulva or anus. A cut-open condom or a piece of plastic wrap works in a pinch.
• Gloves (nitrile or latex) for hand sex reduce transmission risk from cuts and hangnails and also feel great with lube.

Testing

Testing is the only way to know your STI status; many infections are silent. A reasonable cadence:

• Every 3–6 months if you have new or multiple partners.
• Annually if you're in a closed or low-activity arrangement.
• After any unprotected encounter with a new partner.
• Whenever you have symptoms.

A full panel typically covers HIV, syphilis, gonorrhoea, chlamydia, and hepatitis B/C. Herpes (HSV) is usually not on a default panel — request it specifically if you want it, and know that a positive result requires careful interpretation since many people carry it asymptomatically.

PrEP and PEP

PrEP (pre-exposure prophylaxis) is a daily medication that reduces HIV transmission risk by around 99% when taken as prescribed. It's recommended for anyone whose sexual life involves regular potential exposure. Ask a clinician.

PEP (post-exposure prophylaxis) is a 28-day course started within 72 hours of a possible exposure. It's emergency care — sooner is much better. Most emergency rooms can prescribe it.

Vaccines worth knowing about

• HPV vaccine — recommended through age 45 in many countries; protects against the strains that cause most cervical, anal, and oral cancers.
• Hepatitis A and B vaccines — both relevant to sexually active adults.
• Mpox vaccine — available in many regions for higher-risk populations.

Talking about it

The conversation gets easier with a script. Try: "I get tested every X months and my last test was clean. When were you last tested?" Normalise, don't dramatize. If someone reacts badly to the question itself, you've learned something important.
