this may sound stupid but it's my experience
i got a blowjob by this girl at SPA last summer while i was E'd out of my mind. i came like a motherfucker and the next day when i was having an abuse sessions at my apartment i noticed blood in my semen. i called my doctor, explained the situation the previous night, and he said that it was most likely caused by a forceful ejaculation and to give it 4 or 5 days to see if it goes away.it went away in like 3 or 4 days and never happened again.
i don't knwo your situation as far as how recently you have had sex, but it's just an idea. it happened to me and i was fine in a few days.
darknight!!!long time no type my friend!!!
yeah, i pull no punches. i usually just say what pops in my head. most people think i'm insane , but i find the honesty refreshing,hahaha
