I bought a Penthouse and a Playboy, put them on his lap and told him to go through it and I'd be back in a 1/2 hour. When I returned I informed him that what he just saw was an unrealistic image of what a woman is. I kept it real and honest and covered EVERYTHING sexually related. I also covered the feelings (emotional) portion, birth control, RAPE and what it does to a lady.
May be the right way, may have been wrong. But I wanted him to feel that if something come up, he would feel comfortable talking to me (I also told him he could call his uncle) about this instead of relying on the word of a buddy that "thinks" he knows it all.

Good luck with your venture, it is definately awkward but thats part of being daddy I guess!:thumbsup:
