I used to think that "outie" belly buttons were really tiny little penises, and "innie" belly buttons were miniature vaginas. I thought that the real equipment was only used for the bathroom and it was really the belly buttons that were involved in sex. So, since I have an innie, I was always afraid to hug my friends with outie belly buttons, even if they were girls, 'cause I didn't want to get pregnant.
