I am a male living in the US. 12 hrs ago I might of had an exposure. I was the receptive with a transexual. The person had a condom on prior to insertion. After about 30 seconds to 1 minute I pulled away cause I didn't feel comfortable. When I stood up I notice the condom was stuck to my anus. I ask the person if the condom was on and the person replied yes, but I'm not sure. I text this person a couple of more times if he was absolutely sure the condom was on. He replied yes. I asked if he knew his HIV status twice but nebver responded to the ?s. So I'm worried yhat I might have been expose and should I take PEP. Thoughts and risk? Thanks.
