I am a 21 yo male guy, I've met with a men whose HIV I do not know. Previous to the encounter I had an episode of diarrhea with following anal burning (probably some bloodless hemorrhoid) . During our sexual intercourse I received oral sex (w/o ejaculation) rimming and anal fingering. Now he fingered me with the same hand he used to finger himself, then we had sex (I was active and used a condom, who did not break) (It was dark but there seemed not be any blood whatsoever from both of us, as soon as I went home I checked my *** to see if there was blood but it was fine).
My questions are
1) Assuming the worse, which basically is that he is HIV+, was his fingering firstly his *** and then mine a risky activity?
2) Do I need PEP (As I write I'm still in a 4hours windows of the potential exposure)?
3) I am a blood donor, do I have to report this as unprotected potentially infected sex intercourse?
