It's ignorant to not talk to your kids about it or to (not) make it seem as magical and cool as it actually is. They (teenagers) have a TV; they know what sex is... Educate them. Let them know that they wouldn't be here without it. It is a beautiful thing and it is magic and it is when you connect with somebody - and it isn't how much you're worth.
