Saw my gyn to see why I'm bleeding during sex. She even checked me down there and they said nothing is wrong. Why do I still bleed during sex?

Bleeding during sex. There are a couple of possible causes for this problem. Small tears can occur in the vagina that can bleed, the cervix may be irritated and bleed or there is a build-up of tissue in the uterus that is released with cramping during sex.
