When I was a kid and my dad gave me the "birds and the bees" talk (I was about 8 or so) I thought that people only had sex to have a baby. When my dad told me that people also had sex for fun, I thought he was bullshitting me. I guess I didn't realize sex felt good, so I didn't get why people would do it for fun.
