Hi, I had unprotected sex with this girl twice, the first time was about 4 1/2 months ago. During intercourse i was on top of her with her legs over my shoulders, i was going deep and I was feeling something inside her.......anyway.....she said it was hurting her a little......but i kept going and began to penetrate hard until I pulled out a ejaculated on her chest. I then noticed blood on my penise, she said she wasnt on her period. The next day she had to see the doctor because she was bleeding and cramping and she was scared, so she went to the Doctor......she never told me what caused all that, can you help me?
