Let me suggest one more book (I know, consult with the W first). It's called The Five Love Languages by Gary Chapman.
It talks about the different way people express and need love. You obviously need to be touched to feel loved but your W may not feel that way. Not that she isn't interested in sex but that it isn't important to her.
She needs to find that it IS important to you. Not only physically, but emotionally.
BUT (here's the tricky part), she may need to feel loved by you first. Maybe she speaks a different language??
For instance, my W doesn't need sex or touching to feel loved. She enjoys it but she doesn't NEED it. She needs affirmation - she needs to be told she's beautiful, confident, heard that I'm proud of her. THAT makes her feel loved.
When she feels that and understands that I need to feel love a different way, she can accommodate that.
Make sense? Almost like a "I'll scratch your back if you scratch mine" kinda thing.
By the way, you're not alone in that boat, dude
