I I beleive it's very wrong. It's very wrong to determine the value of a woman by how big her boobs or ass are or how hot she is, or a man by the size of his peines but you should rather judge them by their personality. Of course it's ok to have preferences but treating people badly for something they can't change and are born with is as bad as racism or sexism. Actually one of my feminist friends made me aware of this and it goes for both genders.
By personality I mean if they have Good qualities, are loyal, kind, loving, care about you or they're greedy, use u as a sex object, cheating, disrespectful, liars
