When I was about 10 years old, I knew that a penis had to go in a vagina to make a baby, but all I could imagine a man could do when his penis was inside was to urinate. I was so sure that the words "God shed his grace on me" meant that he peed inside of a woman. Doesn't seem very logical now, but it made sense to me at the time.
