Sleeping with a boy could get you pregnant - as in, sleeping in the same bed with one. This led to 9 year old me being terrified when my parents expected me to share a hotel bed with my younger brother!

Until I was about 12, I thought a condom was like a pencil eraser the man put up his pee hole to keep the sperm from coming out. Thus the term "Rubber"

I thought you could tell if a women was pregnant 1-right after the deed and 2- just by looking at ones woo woo.

That if you had sex once you get pregnant instantly -_- I blame thy mother.
