Last Friday I met this girl at the club, and we ended up going back to the apartment, at this point I was kinda drunk but I still remember. We start having sex, and it goes on for like 10/15 minutes? Then all of a sudden my penis went flaccid and I couldn't get it back up. So I performed some oral sex on her, and after abit I had a brief 5 minute penetration. I don't remember ejaculating AT ALL during sex, and I didn't ejaculate after either. In fear that she was pregnant I found her Facebook and contacted her, she says she took plan B on Saturday morning (around 10 hours after intercourse), although I don't believer her that much, maybe I'm overreacting and being way too paranoid .. She wasn't on the pill either. She also said we met about 3 days after her period ended, and also to add, the last time I ejaculated prior to that was about 4/5 days before, so precum shouldn't have any traces of sperm in it.Am I in hot water?Thanks!
