Do you miss being around other races?
Yeah, sometimes. I see a lot of white people at work (other teachers).
I saw a black guy yesterday, but I sometimes go weeks without seeing white people. Of course, there are foreigner hangouts (Starbucks, ex-pat bars) if that's your thing. Still, there are very few black people in China.
Sometimes, some Chinese people from the western provinces who visit here, will want to take a picture with me. I think I might be one of the first white people they have seen. It's a bit awkward.
As to the booty question, most Chinese girls are skinny, but there are probably more voluptuous ones than you might think. I saw a fat ass when I was out running this morning.
