I say this with kindness, how should we know if you should trust the other person? PEP, however, is not supposed to be used just for random sex but when the other person is known to have HIV. A better question for the other person is does he test and when and what were the results. But a one time unprotected anal sex exposure is LESS THAN ONE PERCENT risk. I'd not have sought pep for your exposure. We can't tell you if the guy wore a condom or not. Up to you to you to stay sober enough to be responsible, you know? So, your choice. PEP is hard to take and I'd not take it. You can ask the guy about his most recent testing and get a 4th generation test at 28 days to confirm you don't have hiv. good luck
