I've been married to my husband for almost 25 years, 4 kids. I love the man dearly, and we have both stayed in shape so there's no problem with physical attraction. I just don't want it that much anymore! I've had blood test, exams, etc and I'm perfectly normal. But even though I don't want it he does, so I do it for him. Once we're in the middle of it I enjoy it well enough, but it never occurs to me to initiate it. I actually put a code phrase in my Outlook calendar to remind me to show some interest and get him going. I make sure it's done twice a week, minimum. I wish I knew why I no longer have an interest in sex but I'm not going to lose this guy over something like that, so I force myself to show an interest. I hate that I feel this way but he doesn't know that I do therefore I'm going to keep this going; I don't want to lose him because I do love him. He is good to me, kind, works hard, is affectionate and I am the same way toward him. The difference between us is that sex is still important to him but not to me.
