want some science? great.
most men are ass men. rather, waist to ass men. when men say women have a nice ass, they mean that she has a small waist size relative to her butt. a 0.7 waist size relative to the butt it what most superstar models have. the reason men find a big butt so attractive, is that a butt indicates how wide the hips are (hips and waist are different things fyi). we've been programmed for thousands of years to propagate our genes as effectively as possible, and a large part of this is choosing a mate who wont die when they have your baby. a .7 waist to hip ration eusures the maximum child survival rate, which is why men prefer asses.
now, no joke, im off to write my bio final.
