P.M.
I've been married 33 years to a wonderful man whom I love dearly, but we went a stretch of several years during which his childhood religious training about sex had him convinced it was unnecessary. God, those years were hell for me, because I still found him attractive, and because I promised to be exclusively faithful to him when we married, and because my sexual needs did not stop. I thought a few times that I'd have to move out just to stay sane.
For the last few years, we have reconnected, and my husband has become a freer and more generous lover. He admits it has improved everything about our marriage, and is surprised to find that he can still enjoy sex with a saggy 60-some year old woman. And being married has changed from an ordeal for me to a happy partnership again.
Please don't ignore your husband's needs. They can be as acute as a starving person's need for food. You will not be able enjoy sex with your present attitude, sweetheart. And your marriage will suffer for it. I suggest you talking to your doctor and a counselor about this very big problem. It's not just his problem, it is yours, too.
