Can't really comment on the size of female butts in DR, but have you ridden the subway lately in NYC? Good God !!!!!!!! In a row of seats that was made for 5 people, you are lucky to squeeze 3 in there.
It seems the darker the skin color, the larger the butt. I know that is a generalization, but there is some truth to it. Also, dark skinned men seem to fancy the extra large butt'd girls more than their caucasion counterparts. (I know, another generalization)
Yeah, NY is eyecandy city
