Hi, I am 16 and have been with my boyfriend for 2 years now, and we have had sex a lot but not everyday. Two days ago we had sex for a while that it became dry and raw. When we tried to have sex like a hour later it hurt really bad when he put it in, and now it burns really bad when I pee, also when I wipe there was a little blood on the paper, but the blood only showed up once. I checked in the mirror and its like red on the inside walls on my vagina.
