To an extent, perhaps. But if a guy lived in a paradise with perfectly proportioned, curved, and fit women I don't think he'd start pining for Sally McFatass.
The example of men wanting thin women because of the rate of obese people in first-world countries isn't a good one. First of all, the average (happy, V?) guy is never going to prefer someone obese. Secondly, rising rate or not, obese women do not constitute the majority of women, not even close. So it isn't thin women are 'scarce'.
Tan was also mentioned, and that's always been interesting to me. In the western world, tan = hot. But in the eastern world (perhaps only far eastern, not sure) pale is far preferable. Is that due to scaracity? Or mainly cultural. Because its not like there are a lot of tan women in Japan, or a lot of pasty ones in the Mediterranean.
But how could this have been scarce? I think it has to do with wealth. This kind of physique for a woman suggests reproductive health, but also the ability to afford it. Wealthy women (and men) could afford to stay indoors and eat all day, as opposed to the less wealthy who generally worked harder, ate less, and spent more time in the outdoors (and therefore got tan and much thinner). There were probably a lot more peasants for every rich person, too.
Yeah, according to a Chinese friend of mine (which may or may not be a valid source. But she is actually from China) says the "rich people stay indoors so pale is hot" mentality is still the case over there. So there's definite truth to what you're saying. But I still dunno if that relates to scarcity or not.
I think there's definitely the whole "want what you can't have" on an individual level, but I dunno if it actually applies to entire societies.
I'm a bisexual girl. I love my bishes.
I find hairy muscular men repulsive. I find facial hair to be completely disgusting . Body hair is just plain revolting . You can keep the ugly cavemen. I don't know why any female would want a man that looks like and ape. too close to bestiality for my tastes.
I'd much rather date a girl than a roided up ape anyday.
