I get that. I knew more about sex at that age than most did growing up. My mom had me watch videos of women giving birth, left around all sorts of human body books, etc.. I got in trouble many times for using the information the wrong way I know for a fact that somebody in my daughter's class came home asking what "sex" meant, but so far my daughter hasn't. I'm waiting for her to, though. Honestly, she thinks a woman can have a baby w/out a man. She does not get the concept that you need two people to make a baby. So I don't think she knows about sex yet... or if she's heard of it, she doesn't "get" what it's all about.
