Men lust after women with big ass centuries ago because, for them, these women are highly attractive and sexy, and that belief also came from the olden days where women with big fat ass are more apt for reproduction. Men in the old days would rather have women who have huge booty to ensure they will have plenty of offsprings. But then in the years that follow, like how it was in the 80s where women would rather have a shapely waist instead of having big ass for fear of being ridiculed and being called a fat ass, or thunderbutt, but gone are those days. And, thanks to JLo, who even insured her big booty for millions of dollars. Now, women would exercise, put some padding there, or have an ass enhancement to be more attractive to the opposite sex. Some just want to have more confidence when dressing up as they feel sexier having a bigger, fuller, and rounder butt.
