In some cases, it is a matter of perspective I think. I say this because about 3 years ago I had a 3-sum with a girl from work and a black guy we both knew (was a strange situation, but that's another story). I was surprised (astounded, actually) that I was pretty much the same size as him (I'm 6.5" x 5.5" around), maybe a little bigger than he was. But the girl kept raving about how "HUGE" he was. So I thought I must be huge too (at least to her), but it wasn't the case, according to her mine was just "OK". I thought it to be weird because I saw with my own eyes that we were about the same size. So in my personal experience I know that there are average sized black men, don't know about Asian men though.
