I bet they comment on your small Asian dick, too.
I'm not Asian, but have discussed the subject of race/dick size with many mpa's and sp's. (I'm white and very average btw)
Their generalization is that most Asian guys are "growers not showers" and that while they may appear small when flaccid, they usually grow to average size or better when erect.
For what it's worth. And in truth most of these ladies couldn't care less about your dick size, unless it's too big and hurts.
