My boyfriend and I have been dating for a year and a half, and we've been trying to have sex for about six months now. We have tried about eight times, but it was extremely painful and each time I bled slightly. A few days ago, I was sitting on top of him and I felt my hymen give away, at leat I think that's what it was. I bled A LOT. It looked like someone had poured blood all over his sheets and all over him, and I dripped all the way to the bathtub where I washed off. I waited a few days, and we tried again, with the same results, although there wasn't nearly so much blood this time. I'm in massive amounts of pain every time I pee and wipe and even if I sit down the wrong way. Advice? Concerns? Please help!
