I had sex, maybe 15 minutes ago, and its not my first time, ive been having sex for a while, but i started bleeding, i thought nothing of it, we stopped, i put my pants on, and went home. i came home to go to the rest room, and there is a 3 inch, piece of skin, pink like the rest of me, and its hanging out of my vagina. what do i do? i feel some discomfort inside, but the sting thing doesnt hurt.
