I used to think that you "weed" and "pooed" out of the vagina... girls only had one hole (not even a urethra) and boys had 2 holes b/c they can't poop from their penis
A childhood belief about weeing and pooing

others believed things like this
- I actually asked my mother if mixing girls' poop and boys' poop would cause an explosion.— kraine
- I used to believe that girls pee was in their poop, because they have no penis.— s
- I thought that the difference between girls and boys was that girls have teeth.
Anon - When I was little, I thought that since boys stood up to pee, they could stand up to poop.— Lacey
- I used to believe that little boys grew up to be girls and little girls grew up to be boys. — Darin
- when I was a kid, I used to believe that only girls could be my friends and all other boys were my brothers.
