Hmm...I've often wondered what my fascination with asians is myself :P
For me, it is one particular type of asian. I dig Koreans. My current girlfriend is Korean, as was the one before.
The body part I am attracted to most? Well, I love the straight dark hair, but #1 would have to be the eyes. There's just something about my girlfriend's eyes that drives me insane.
A nice ass, and a good pair of knockers doesn't hurt either

(both of which she has! woohoo!)
I wouldn't go extremely out of my way to find an asian girlfriend/wife. I've gone on dates and had girlfriends of other races, so I'm not an exclusive-type.
To be honest, I wasn't looking for asian girlfriends in either case, it just turned out that way. Needless to say, having two Korean girlfriends in a row caused a ton of joking among my guy friends about me having some weird fetish or something.
Some people just have the fever though!
