I'm right in that boat with you Honey! I've also come to the conclusion that my husband fits the arousal=desire pattern. He's fine once I get things started, but damn! It's frustrating to always have to be the one to do that.
I'm still hopeful, he is still going to counseling, and he's doing better about talking with me. But just last night he made it very clear to me (indirectly) by mentioning that he had told his C that there are certain things he will NEVER talk about...the topic was his sexuality. There is something buried that he will not let out.
We are growing closer with our EC because we are learning to communicate better...but the sexual frustrations are still there. All I can do is work on myself, pray, be an awesome mom (like you), and love him.
