I agree with everything you say, excpet I would add that it is not about weight, but just being FIT for your age. We all age and change, we just need to stay fit for our age group. Most men are OK with this, but some are more set on the attractiveness part.
What I believe is more important is that the women feel great about herself. I have seen those two lady doctors on TV they deal with sex and realtionship issues, and in the top 3 things they want everyone to do, is GET IN SHAPE. They know that one of the BIGGEST issues in relationships is that women have a BAD BODY IMAGE of themselves. I know this is the case in my marriage. My wife is so down on her own looks, that she feels LESS sexual. Heck, I think that bad body image by the women can actually lead to sexual aversion, she literally becomes uncomfortable being NAKED, which eventually has to lead to sexual aversion. Literally , the more comfortable you are with the way your body looks, the BETTER the sexual partner you likely will be. So this is why the experts stress, GETTING IN SHAPE!
And, no, you do not have to be modelesque, just be comfortable with what you look like. GET FIT!!
P.S. I think another reason they stress working out, is that exercise probably creates testosterone which drives sexual desire. There are other benefits to working out that also probably lead to better sexual/relationship feelings.
