In continuation with the above question , there was no sex involved, only foreplay as in kissing on cheeks/licking and licking the nipples.
A help would be great.
There is no risk involved in what your friend did.
Just as a precaution, should he go for a test anyway ?
If there is no risk, there is no reason to test.
One last question.
Hypothetically is it possible if a HIV positive person with a cut in his mouth lick the nipples of a female and a droplet with the HIV virus falls on it, A few minutes later another guy whom the prostitue sleeps with licks that part of her body again and takes it inside his mouth and gets infected?. this will be my final question.
Not playing the "what if" game. It was and always will be no risk no matter what you want to invent as a situation.
