Ok, so I know what I did was really stupid, but I'm really freaking out. I met this prostitute and went back to her place. Neither one of us had any condoms. Long story short is we had really rough unprotected anal sex 4 times. I ejaculated in her anus all 4 times. The third time it seems that there could have been some bleeding from her anus. The 4th time, when I pulled out there was definitely blood all over my penis. I washed it off and she did have hand sanitizer in the bathroom which I applied generously to my penis. Is there any chance that would help? 2 other details about the encounter stuck out to me. 1st she had several weird looking lesions type things on her back. 2nd, as I was getting dressed and getting ready to leave I noticed a couple of needles and what appeared to be some kind of narcotic with them. I asked her what it was for and she said just something her and her roommates occasionally do. I'm assuming there could be some needle sharing going on there but not sure. So guess the big question is, how likely am I to have gotten HIV from this encounter? This was about a month ago, is there anything to do at this point besides wait the full 3 months to get tested?
