So my boyfriend and I just had sex and we were going at it pretty rough. All of a sudden he slipped out and then thrusted right into that skin between the vagina and the anus. It hurt so bad and I immediately started crying and then I lifted up and we realized there was blood EVERYWHERE. It still hurts a lot and I'm still bleeding so I grabbed a pad. Is there anything I can do for it or are there any precautions I should take?
