Lot of great reasons in this thread. Beautiful soft skin and petite bodies. Tiny pussies and assholes with tasty brown nipples. Most of the Asian girls I have encountered in the states are bright, beautiful and extremely clean. Outside the states the results vary by education and country. In general they are up for anything in bed and are down for experimenting. Asian girls seem always ready to please their man and have an uncommon appreciation for sex. Did I mention they're incredibly loyal?
I'll add that it's rare to see a 200lb Asian girl. Try to say that about white or black girls. Now if you're into the BBW, I would not be traveling to Asia anytime soon.
