When I was 8 or so, an older friend told me that masturbation meant "playing with yourself". I took her literally. This resulted in two things:
One day at day camp, I heard the word "masturbation" on television, and proudly proclaimed to the teacher in charge "I know what that word means!"
Shortly afterwards, my mother gave me a book about "the facts of life" and it said that masturbation usually resulted in an orgasm (which I somehow got into my head was a bad thing) and was terrified that when I played alone in my room I was going to give myself an orgasm.
