when i was a kid i keep hearing the hymen described as the thin tissue barrier that goes across the vaginal opening

so i was freaked out when i heard about mensuration because omg if the hymen wasn't broken yet it would all back up and I'D DIE

so i asked a teacher and she was like 'yes it is solid but the blood makes it through"

so i was convinced i had a magical portal of some sort in my vagina that let blood though but wouldn't let anything in unless it was my husbands dick
