I had gay sex with a guy last night after we left a club and I went back to his apartment. I was really drunk but I remember giving and reciving oral sex and then giving him protected penetrative sex for a really short time. I was really drunk, and it might just be my mind playing tricks on me but I'm paranoid the condom might of broken. He said he hadn't had sex with a guy before, even though he was also really drunk. Am I at risk of HIV? Do I need to take the PEP drug, bearing in mind that I'm still within the 72hr time frame?
