I had unprotected anal sex (twice) with a friend 2 days ago. I learned the next day that he has been HIV positive for over 17 years, had an active disease at one point, has been on anti-retroviral regiment (currently on Ziagen, didanosine and lexiva) for years and has had undetectable viral load since 1999 (over 10 years). Naturally, I am freaking out. I read about PEP. Can anyone recommend what the best move I can make now? Thanks for your help
