I am 18 and first had sex about 3 yrs ago with a boy and bled the first thre times I had sex. I didn't have sex for about 6 months and then started dating my current girlriend. The first few times we had sex I was fine but then ater 3 or 4 months of us dating I bled a litle every time we had sex... (sory for the details ahead) One night we were having sex and it got kind of rough and when I looked down there was blood everywhere... down my legs, on her hand, just everywhere. Why did this happen??
