@hue-man,
I am not a male, but as someone who is attracted to women, I figure my opinion is valid.
I tend towards bigger women, with fuller figures. I really like a stocky build that implies inherent strength. Hair color is usually brown or red, and eye color is usually dark. At the same time, I have a somewhat contradictory preference. I enjoy A cups, but only on smaller women, which means I have two ideals. The small petit woman, and the voluptuous woman.
I think our ideas of beauty are a case of nurture rather than nature. Yes, some of it is based on evolutionary ideals, but not all. We do not always seek out the healthiest specimen. There was a study, actually, on people with fetishes. I remember specifically one woman, with a fetish for beards, who was shown three men, one in ideal condition, two in poor health, and asked to choose. She chose the one who looked like a meth addict over the healthy, muscled man because the thin one had a beard. Later, without his beard, she didn't recognize him and rejected him. You can say fetishes are a special case, but I don't believe they are. Everyone has 'preferences' and most times those preferences work as the woman's beard fetish did. We can, through conditioning usually outside our control or awareness, override the evolutionary guidelines for a choice partner.
