Why do I see so so many black men with fat white women?

My boyfriend is black, and most of the guys I've dated are black, and I'm a size 6. That's kind of a mean stereotype that probably got started from some of the rap songs out there, and black men do appreciate a woman's natural curves which is nice since most of us are not twigs. But when I see interracial couples, there's quite a diversity between race and size, actually! Love sees on the inside.
