Women are ever so concerned about their own weight and appearances , do you think they want to feel bigger or on par with their boyfriend and people to notice it when they go out anywhere? I think a lot of guys view what women like or don't like in men, from how we judge women, when the fact is , women might date someone for all sorts of strange reasons that they don't even understand themselves. Besides which, I think a handsome face trumps any kind of male physique, you could have the body of arnold,or some hairless lean muscular slight effeminate pretty boy,but if you have a face like a bulldog chewing a wasp ,the handsome guy with a skinny fat, average joe body would get more notice.
But even then I wouldn't put a weeks wages on mr handsome , as women change their minds like the wind. And she could settle for a fat man because he makes her laugh or their star signs align or some stupid shyt.
