I have been married for 20 years to a great guy. I have a big problem, though: I have never liked sex with him. He is a great father and husband, but the sex has never been good. He is the best I have ever had, but if his penis fell off today, I would probably be doing a happy dance in my head. I have to be drunk to have sex with him now and he knows it—and it hurts him. I don’t think I want a divorce. I wonder if letting him sleep around would be the answer. I just worry that if he actually did that I would regret that decision.
