Until I was in 8th grade health, I didn't know that girls had 3 holes down there. I always thought that the penis went into the pee hole. I always imagined my pee hole being pulled and stretched open for the guy, or, during sex, it would open like a mouth and sorta eat the penis. I also thought that your poop babies out. I was shocked that I didn't know what I had down there.
