Hi, I am a gay male, and I had my first protected anal sex with a condom with a man last night. I was the bottom. After sex, I felt a bit discomfort with my anus. But for some reason, I am very worried whether I got HIV. I used condoms during the whole time. And did not use the same condoms for anal and oral sex. At the end, I think the condom did not leak, but i am worried that if his penis was sliding in and out, will cum got leaked, even though the condom is on the whole time? I would like to hear your opinion about this and whether I am over worrying.
