An associate of mine has a strange obsession with non-Black women's asses. He will always hype up a "pawg" as if she was a marvel of nature, and then when she is revealed, it is evident that her figure on a Black woman would be totally unremarkable. It is tiresome when guys try to play up some non-Black or non-Latina woman's ass like it is amazing and it is barely average. Or they will swear up and down a White woman has this amazing ass on par with a Black woman, and it turns out to be a fitness model or crossfit athlete who has a shapely ass but not a phat one. Most typically it will be a White woman who has clearly undergone surgery. A few naturals are out there, but it's not nearly as frequent as what some guys will pretend.
Asian women with those natural asses are far less frequent than the White women, but they exist. I have seen one on a Korean woman that I know was 100% natural and she never wore heels. It wasn't the world's finest booty, but it would have caught my eye on a sister, so it definitely stood out on her. The rest of the asses on par with Black/Latina booty I have seen on Asian women have been from surgery. The only consistently remarkable physical trait I have noticed in Asian women is that some of them have very wide hips.
