[Question #10954] Mutual Masturbation HIV Risk

18 months ago

Hi Doctor, Quick question. Hooked up with a guy yesterday (male here as well). He gave me a blow job, and we mutually masturbated, my penis shaft against his. He ejaculated on my body, and then maybe 15-30 seconds after ejaculating on me, he used his semen that was on me and tried to masturbate my penis with it almost as a sort of lube. The semen definitely touched my urethra opening but I wiped it away within seconds and ejaculated shortly after. I am circumcised if that matters. If he was infected with HIV, could this activity pose a risk for HIV? I’m worried that the semen was pretty fresh and sitting on my warm body which could mean it’s still infectious.

Your two previous questions on th forum covered oral sex and the risks for anal sex, even though you had not yet had such an exposure. So you know from those discussions that receiving a BJ was little or no risk, and certainly there is no risk for HIV or any other STI by skin contact with a partner's semen. The new aspect of this event compared with the others is your specific question about your partner masturbating you using his semen for lubrication. This was zero risk for HIV and all STDs. Not enough bacteria or viruses can be exposed to susceptible cells by such contact. This was a non-event in terms of HIV risk.

Let's make this your last question about your low risk exposures with other men, i.e. until you have anal sex, either top or bottom. Until that happens, you can concisider yourself at zero risk for HIV, with no requirement for PEP or even for HIV testing.

The oral sex events carry risks for gonorrhea, herpes, maybe chlamydia (but very low risk)) and perhaps HPV. But all low enough to not require testing after any single exposure. assuming you do not develop typical symptoms of those infections. We have previously discussed that it would be wise for you to keep condoms handy in the event you go ahed with anal sex in these circumstances (even if not intended for any particular occasion) and also discuss HIV status with your potential partners before having any contact.

Let me know if anyhting isn't clear.
