basically the other night i had sex with a friend (female), and during us having sex, i was going a bit hard on her, all of a sudden she said to me " you've split me!" then she just rushed to the toilet, i knocked on the bathroom door to see what was wrong, she opened it and her vagina was bleeding, she was pissed off at me, and she asked me if i could leave, but now i feel bad i mean i've been trying to call her, she not picking up, and she's a friend so i'm worried about her, and i feel real bad, what do i do now.
oh and btw she isn't a virgin
