HIV Prevention and Testing > Am I Infected?

can some experts help me here

(1/4) > >>


I am gay and at the weekend I slept with another guy. We played around and had protected sex (condom and lots of lube so no worries there), but we finished off by masturbating next to each other. He came first and came over my chest, which left a pool of semen in one place. Without thinking, then I dipped my penis head into the cum a couple of times and finished myself off after that.

I know a lot of places say mutual masturbation is none or little risk, but if a guy can get HIV from his penis being covered in anal or cervical fluids during intercourse (and i guess fluid touching opening of urethra), then surely getting fresh cum over the penis is a risk too?

Should I be testing out to 3/6 months after this exposure?  I know from looking at other threads that you guys can be great with some science to validate what you say. I would really appreciate someone explaining the risk in this case.

I know most of you US guys will be sleepnig, so will log off now and check back later.


You don't need to be worried about HIV infection. Mutual masturbation is not a risk. HIV slowly becomes inactive when exposed to the air. That's why infection occurs inside the body (i.e. unprotected anal and vaginal intercourse). The risks you're trying to stretch for are purely theoretical, and don't happen.

Just use condoms for intercourse and you'll remain HIV negative.

Take care,

John is right, there is no risk of HIV transmission from mutual masturbation. Also you had protected anal sex so no worries there. Well done!

It's a wise idea for sexually active people to have a full STD screen at least twice a year. A full STD screen includes an HIV antibody test. If it's been a while since your last STD checkup or if you've not had one before, then you might want to consider making an appointment with your doctor or local clinic.

Please note that I'm not recommending you test as a result of the encounter you describe in your post. Read our Welcome Thread thread. It contains links to our transmission lessons.

Keep using condoms and lube and you'll be fine.



Andy Velez:
Just chiming in to concur with what has already been said. Masturbation in the manner you have described is a very, very common sexual activity. If it engendered any risk we would have known that long before today.

Often we get questions related to masturbation and concerns about whether a bruise, nick, irritation, pimple, etc. on the penis orin the public area constitutes a risk. The bottom line is there has never been a documented case of transmission through mutual masturbation. You aren't going to make history by becoming the first.

Also, although there isn't any need for testing in relation to the incident you're concerned about, for future reference it's 13 weeks and not 6 months that is used as a reliable testing point as recommended by the CDC. Six months is only suggested if the person is an IV drug user or has a severely depleted immune system because of cancer treatment or other such major health problem.

Happily yours is not an HIV situation and no testing is necessary. 

Hello sorry for coming back to this one
In the last few days there has been a lot of stuff around about how much easier it is to become infected if you are uncircumcised, basically that the foreskin is a great place to pick up infection as it is a mucous membrane.
If you rub infectious fluids into such mucous membrane (i guess like any topical cream) then surely the virus would be absored and exposed to those receptor cells abudent under the foreskin? SOrry if i am misunderstanding some basic science here, but I can't see how using cum to masturbate is no risk, when even a brief unprotected insertion constitutes a risk?
I know that HIv becomes less viable exposed to air, but if the cum contacts your penis within seconds, surely it is still infectious?

Can someone help me out here?
