My wife was telling me about what her colleagues at work say about discussing the "birds and the bees" with their children. This is something I would be happy to put off as long as possible. I've already decided to keep GoofGirl in a burqa. GoofBoy, by comparison, should be easy to handle. I know how to keep girls away from him. I'll give him time-tested advice. I will tell him every technique, trick, and move I've got (mostly stolen from Seinfeld episodes). If that doesn't keep the girls away - far away - I don't know what will.
At least that's how they worked for me.
