Up until I was about eight, I thought sex was only done to make babies; I had no idea that it was pleasurable or that people did it for fun. I knew all about how the actual act of reproduction worked (with the exception of penises having to become erect first), but not why people would do it except perhaps out of boredom or a sense of duty.
