I was just thinking. Of all the girls I have dated including my wife, I have yet to know one who thought their butt was too small.
They all thought it was too big and often did a lot of exercise trying to make it smaller.
Actually they were all just about the right size.
I’m guessing you didn’t date black women.
I recall reading in Nature I think it was that in societies where food is plentiful, thin = beautiful. Where it is scarce, fat = beautiful.
