Another thought I had was that money or success or lack of it can have a similar affect on a man's libido as overweight or getting wrinkles can have on a woman's. Of course, this just reflects a certain sexism and there are plenty of men with poor body image and plenty of women with poor self image due to lack of success, for instance Choc's wife seems to feel this way.
The summer I was 20, I hung out with 2 other girls who were also attractive and HD. One of the girls was dating a kid from a very wealthy family and she would bring us with her to parties his crowd would be holding. In a weird way I think being a HDW was less of a liability in this social setting than in others because her boyfriend could never know if she was balling his brains out because she really liked him or she really liked sex or because he had a cool sports car which he kept in his underground garage.
I've read that some women subconsciously become overweight because they don't want to be desired just for their bodies or conversely because they don't want to be rejected for their personalities. Another thought I had was that maybe if a woman was overweight she would become LD because she wants to keep a certain desire balance in her marriage. She's subconsciously following the economic rule of scarcity. If she feels like her sexiness has a low inherent value, the only way to increase its value is to make it a scarce commodity.
