Once I finally understood that the penis had to be hard before entering a woman's vagina, I just figured that a grown man ALWAYS had an erect penis. That's what happened when a boy went through puberty--he got his "permanent" erection.
Ouch.
A childhood belief about rude bits

- i used to believe that a penis was the same as a vagina except really long— *stupid*
