Answer: You say you "can't stand sex, feel nothing, enjoy nothing, have had years of disappointment, a marriage that is falling apart" and then ask me to tell you that "its not psychological?" What else could it be? You've done the right thing by first seeing your physician, but I wonder if you've been completely honest with your doctor. If you truly "enjoy nothing" (called anhedonia), that is one of the criteria for depression. Other areas include: difficulty falling or staying asleep, any unusual weight gain or weight loss, mood fluctuations, problems with concentration, and thoughts of suicide or wishing you were dead. "Forcing" yourself to have sex is not the answer. You need some professional help and I strongly urge you to contact a qualified therapist who can thoroughly evaluate and treat your situation. He or she may suggest you see a psychiatrist for medication. A quickie fix is not the answer for you---by your own admission you've already tried that. See a licensed professional. I wish you well.
