I'm sorry I disagree,I feel totally flattened and humilated
by such sex and would rather go without it.You've obviously never had a man sleep with you because he felt it was his obligation even though he was not attracted to you at all physically.I don't care how much he loves your other traits there's no way of masking the lack of physical attraction over the long haul and ther's no way that you're not eventually going to feel horrible about it and there's no way the guy over time isn't going to expect you to express gratitude for his sacrifice.

I think the better way is to acknowledge that age is causing changes that are making the physical attraction diminish and then to decide both on your own and as a couple what options are ok with you in order to deal with it.
