This happened 3 months ago. I met this guy thru grindr. We were naked on the bed. We were doing the penis frottage. I know he was very horny since he has a lot of precum. He put his precum on the head and tip of my penis as lubricant after. After which I decided to wear my loose underwear since I felt afraid that I might get an HIV from his precum since he put it on the head of my penis. He then force to sit on my lap while he was naked and I was wearing a lose brief. I belief he force to remove my undies by moving his butt. After that I realize that the half of my penis was already out in my undies, given the scenario:
What if the head of my penis entered into his anus what is my possibility of getting HIV?
I am not really sure if it entered, but what if since the head of my penis was not already inside my brief.
Sorry to my English
