This reminds me of when a former surgeon general suggested that we start teaching children how to masturbate as a way of promoting "safe sex."
David Brinkley, the old dude who used to host the ABC Sunday morning show, was funny when he said, "Why would we start teaching something that has never needed to be taught before?"
In all seriousness, I'm a long way off from having kids. But, if I had a son and I thought he could handle it, I would like to dialogue with him (**a bit**) about the subject. I NEVER would want him to feel ashamed of jerking off -- I want him to know that it's normal, natural, and that every man does it... I think it would have been cool if my dad had expressed that much to me. Unfortunately, when I was in middle/high school, none of my buddies admitted to jacking off. I thought I was the only one.
