Hello, dear doctor. I want to say that I'm really bad now. That's the way it is. I'm a gay man. I met a man on a dating app a few days ago. We met. I was a little drunk at that time, so I only remember roughly. He was naked and began to touch the other's penis. Then he touched my anus with his fingers and wanted to enter. I refused, but his fingers seemed to squeeze in a little bit. Then he hugged me from behind and rubbed his penis outside my anus for about dozens of seconds without ejaculating. That's all. Later, he saw that I was drunk and didn't cooperate with him, so he left. When I got home the next day, I didn't feel uncomfortable, but after I remembered this, my anus began to feel an indescribable discomfort. I sent him a message, hoping that he would be tested for HIV. He refused and told me that we had done nothing. His attitude worried me, so 55 hours after the incident, I couldn't stand the torment in my heart and went to the hospital for Biktarvy for PEP.
