Please say something that really might be helpful here. Beating someone over the head with the LD stick or putting them in the corner with the LD dunce hat isn't going to help anyone. How about instead figuring out ways to create honesty, goodwill, a loving environment and then seeing what can grow there. How about if that doesn't work despite best efforts looking into medical causes of low desire and working on physical wellness? How about if that doesn't work seeing a therapist alone or as a couple to see if there are psychological barriers.
Morozov,
I am sorry to hear of your marital issues. Read through some peoples old posts. You will get tons of ideas and probably read a little about what not to do. Start with an earnest discussion with your W. Read Sex Starved Marriage, Divorce Busting, Passionate Marriage and other books - see what rings true to you. Work on yourself. Nurture yourself.
