As my mother told me when I was a very little, that girls don't have a penis... I took that literally, thinking that they just lacked the penis but had a single pair of balls there instead.
I used to think they peed standing up out of "pee holes" in there balls. gross eh?
It wasn't till I was about 8 and saw a kid running round naked on the beach when I asked my mother... "mommy, why doesn't she have a pair balls"
