I particularly identify with Lucky's post. Try to make it clear to your W that it's not necessarily sex that you need, but her affection. Your baby is a new addition and you both have some adjusting to get used to.
My problem was weight gain, avoiding sex at any cost, guilt of knowing my H wanted sex more than I did, and my refusal to honestly communicate my feelings and needs. I constantly used, "I'm tired, I don't feel sexy, I don't feel like it..."
Reading SSM helped us; we read the book together. Be careful though, this problem will take work... it's not just a phase.
