HIV Risk from past semen in rectum - please help, young and terrified

[bwolv]

About a week ago I had unprotected anal sex with another man (I topped). I never do this, and I get tested regularly so now I'm freaking out. I made sure to ask if he was STI/HIV free (he says he is, also that he is on Prep) but I'm especially scared because I noticed that when I was topping him there was previous ejaculate already in him (not mine). How much of a risk does this pose? He says he showered before we had sex -would this make a difference? I'm uncircumcised. I wasn't inside of him for more than 10 minutes and neither of us came. Please help I'm very very very terrified and I'm getting the HIV RNA early detection test in a few days but the anxiety is killing me and it's hard for me to keep going on

HIV is instantly inactivated in air and saliva which means it is effectively dead as soon as it leaves someone's body so it can't infect from touching or oral. So washing serves no purpose.
Only sex risks are unprotected penetrating vaginal or anal sex so you had a risk. You can take a duo test at 28 days for a conclusive result. Try to relax until then and avoid Googling or checking for symptoms that won't prove anything so there is no useful information other than to test.
Are you able to communicate with him to see if there are HIV results when he was last tested?

Yes his last test was in October

If it was a duo then the risk period activity is any unprotected anal or vaginal he had from 28 days prior to the test and now. Why was he on PEP?

Sorry , he wasn’t on PEP but PREP

The prep he took is to protect him from others, but it isn't 100% guaranteed to work. So he has that window period that I mentioned above that is in question. For you to be at risk requires that he became positive during that window and then that he did transmit to you afterwards which doesn't always happen. Only a test can determine your status.
