Oh dear, I am a gay man, I just had sex a while ago. and now, I am paranoid. I am on the bottom side. I was penetrated by a man with a condom. The condom was still on when he pulled it out, but he came inside me. and the worst thing is, I have blood in my anus. I'm so worried. I checked the condom, and yes, there was no hole or something. I believe the tip of his penis was covered when he came inside me. My question is, am I at risk? what is the chance of me getting HIV,,,I'm so scared..HELP!!!
