No, really. They need to know about that shit so they don't get STDs or babies or something. And if you have no idea how to approach the topic with your kids, Amy Lang can help you! She's in Questionland all week, giving out free advice on everything and anything you'd ever need to know about talking to your kids about sex. She probably even has answers to questions your kids might ask that you don't know the answers to (a lot has changed—have you seen that show Skins?).

Click here to start asking your questions now, so you can teach your kids how to be safe and smart about sex. And so you don't end up on an episode of MTV's Teen Mom.
