your hymen is inside yoru
vagina, not your butt hole. like the other person said, probably from tearing from your rectum in your butt. now if you had intercoure( vaginia peneration) your hymen could of broke do to a injury, you weren't born with one, or your hymen is flexible or you broke it by fingering or when you were growing it caused the hymen to break. Hymen is not a source of virginty, virginity just means you never had intercoure before.
