when I was little I heard the term "He was inside me" somehow in conjuntion with "got me pregnant"
and till I was about 9 I believed that to get a woman pregnant you have to get inside of her completely
I figured it out after my teacher showed us her pregnant stomach and we met he 6'5 husband (she was 5'4 or so)
