Quick Answer
Safer oral sex: use condoms on penises, dental dams on vulvas, and flavored barriers for better taste. HIV risk is low but not zero; gonorrhea, chlamydia, syphilis, herpes, and HPV all transmit orally. Throat swabs are the only way to detect oral STIs.
- Condoms during fellatio: cut transmission risk dramatically; flavored versions increase compliance.
- Dental dams: latex or polyurethane squares covering the vulva or anus during cunnilingus or rimming.
- Avoid oral sex with visible sores, ulcers, or bleeding gums.
- Regular throat swabs: standard panels miss oral infections — request them if oral sex is part of your sexual activity.
Context Most Pages Skip
Oral sex is often treated as 'safer' than penetrative sex, but it transmits several STIs efficiently — especially gonorrhea, herpes, and syphilis. The risk difference is real (HIV risk is low) but narrower than many assume.
Practical barriers
Cut a condom lengthwise to create a dental dam. Use flavored lube. Avoid barriers with shared toys between partners. The most effective barrier is the one you'll actually use, so find what works for you.
