Ok I was having sex with my friend this afternoon and it was getting pretty intense and all of a sudden I look down when I had her doggy and I see my penis just covered in blood and its all over the place. I really thought my dick was cut or something and turns out it was her that was bleeding. She wasn't on her cycle at the time it had actually been about a week and a half since her last cycle. I want to know if this has happened to anypne before and what it could possibly be. She wouldn't tell me and she was quite embarassed. WTF??
