Two days ago I had unprotected oral sex with a hooker. I found her ad online...She performed oral on me for no more than 5 minutes, then put a rubber on......I have never done that and am now deathly afraid of what I might have......partly because I use a trimming razor and i had a couple of small cuts at the base of my penis oozing some blood...not an excessive amount but you could tell it was there.....I've heard that HIV risk from oral is negligible, but I never checked her mouth for sores etc and i was bleeding somewhat like i said....Im so drained thinking about this crap.....should i get tested for anything...but even if I do, i was told the tests wouldnt show anything because it's too early...i was wondering if i should get on truvada soon seeing as the 72 hour window is coming.....any advice would be appreciated
