Hello, I'm a 19 almost twenty year old girl, and I've been sexually active for a year now. Two days ago when I had sex it was very hard to get in, more than usual, and and the pain was also more. After there was blood and it hurt to the touch. bleed for half the day. The fallowing night we attempted sex again, I made sure I was wet enough, but more pain a lot more and blood immediately. It took me several minutes till I could move off the bed, it felt like I was being raped by knifes. why is this happening??
