Hairdog, I wanted to say a bit more on this topic, because it's really easy to guffaw at the absurdity of your W's position, but maybe analyzing it a bit more might yield better results.
Also, I wanted to set your mind at ease in case you now think you're married to a nutcase... I think your W's position is not at all uncommon. In fact, W has said very similar things on a regular basis - not in so many words, but obliquely, as in "Can't we 'connect' in some way other than sex?" Now you need to know that we DO connect in a GREAT many ways other than sex, and she DOES acknowledge that as well, so her question really is more like "Can't we have sex less often?" For instance, on the "Famous Friday Night", when we were at the hotel and I indicated I'd like to ML before dinner, and maybe again after the show, she was once again asking if there wasn't SOMETHING other than sex that we could do. If I'd had the balls, I would have reminded her that the entire point of going downtown, spending a night in a hotel, etc., was so we could have some time to focus on each other, with no cares or worries or anything else intruding. And what better, more loving, more romantic way to do that than to ML? In fact, what is the whole point of romance anyway?
So I'm thinking maybe your W, like mine, is basically saying "Why does it always have to be about sex?" To which you and I would, of course, answer "What else should it be about?" Maybe the answer to that question would be interesting!
