My husband went through the same thing when my first child was born. He would try to explain why but it never made sense. I finallllllly figured out what was the problem and when I talked to him he stopped being, excuse me, a freak. Anyhow his deal was he was so completely tramatized by actually seing what went on down there...to me...that he couldn't get past it in his mind. He was scared to death to be intimate with me because of what he saw, how um open it gets.....
