LOL.
Not all black women have curvy bigbooty bodies. Not all latina women have that body...
White women have been curvy since forever but it wasn't fashionable so if they had a big ass they would diet it away or hide it.
Now its the in thing so those who have big asses can freely show them off.
Those who don't have but want them can buy them I guess.
Im not curvy at all when I'm at what I like to call my default weight. I look like a toothpick with double D's.
But should I reach a certain weight my thighs and hips fill out and I'm more curvaceous. Hubby will be slapping my ass randomly, even in his sleep he will reach out and give it a squeeze.
If I go overboard I think I look like a whale. And boobs keep growing larger with any weight I gain. So I try to keep my weight down. Coz I end up with ginormous boobs so I end up having trouble looking for large bras and these evil store owners see that its hard to find a large cup size but with a small band size so they hike up the price. Not to mention having to support their weight, my back and shoulders.
The point is its fashionable now so more people regardless of race will let their ass pop.
Some are willing to carry extra weight to get a plumper ass. Or workout more and improve their ass.
Yes the biggest natural asses seem to be on black women... But not all white/other have flat asses.
