Well my ex-wife's lack of libido was a large reason for our divorce. One of the few things we ever argued about. She never would even try to understand the physical intimacy is a huge part of a healthy relationship.

I wasn't ready go give up on sex forever either. I hate to sound vulgar but does he masturbate at all? If he won't go in for individual therapy how about suggesting marriage counseling? Though be warned my insistence on marriage counseling seems to have been the straw that broke the camel's back in my marriage and her asking for a divorce. Of course now I wish we would have split up sooner.
