Hello doctor,
recently I had multiple gay sex encounters - 3 anal intercourses where I was the bottom, and 2-3 quick quick orals with me as the one performing the act. Each time a condom was used, inspected and put on by me. With second man unfortunately the condom was a bit large so it kept rolling down. It didn't slip off but maybe there was some contact between his penis and the base of my rectum (not sure, but maybe).
During every intercourse I kept checking the condom, and other than the mentioned incident, everything was fine.
It has now been 20 days since the first intercourse and 1 since the last. I have been having a sore entire week, and now I seem to have developed a lump on the right side of my neck, just below the jaw. And I got scared and started poking and touching it and now it definitely feels like there is something there. It's not a hard lump, but a lump it is. And I just had diarrhea.
What is your honest thought about my risk? I know a lot of the HIV infections are because of the tender tissue inside the rectum and the friction with penis, but could it also be the same at the base of the rectum?
