I had oral sex, a woman is performing blowjob on me.
I am (HIV negative) male & received oral sex from a woman (status unknown). For about 2 minutes maximum she is doing blowjob. While she is doing, she has bitten my penis head, there was tiny blood on my penis because of teeth bite ( blood is not gushing out) 5 % or less of teaspoon quantity blood I have seen. I have no cuts or anything of the sort on my penis before, and, by noticing the blood in seconds, I pulled back and washed the head of the penis. I haven't seen blood from her mouth membrane. I have been too worried are there any chances of HIV transmission, if she is HIV positives and if she has some mouth ulcers?
I’m much concerned, about HIV risk, so I going to get a prescription drug Post-exposure PEP, What’s your viewpoint on this?
