Question: Hi. I am not on PReP. In a very regretful moment while partying, I joined what I thought was a couple in their hotel room. The two guys began having anal sex until the top finished inside the bottom. Maybe 10 minutes later the bottom jumped over and was straddling me, I then realized he’d put my penis in his anus. As soon as I felt my penis enter his anus I pulled out. It was only maybe 10 seconds. I left immediately because I suddenly sobered and wasn’t comfortable. I learned afterwards that the guys were not a couple and were actually strangers to one another. I have no idea if either one was on prep. Before that moment, I had not done anything to put myself at risk, not even oral. I am very worried because my penis entered the guy’s anus for a few seconds, and about 10 minutes after the other guy had cum inside this anus. What is my risk of HIV exposure here?
