I knew about the basics of sex from a young age, but didn't know about birth control until later. When I was about nine or ten, I heard about how very religious people believed in having lots of children. I thought it was because every time they felt themselves getting horny, they took it as a calling from God that they should be trying to reproduce right that very moment.
