Some guys go for blondes, some for redheads, some like big boobs, some small. For others, a pouty mouth and sultry eyes are all it takes to rev the engine. For others -- myself included -- it is the beauty of the Asian look that send the rocket roaring to life. It is no different, I suppose, than those who go gaga for hard rock, but wouldn't listen to jazz for all the tea in, ahem, China.
As to a fetish? Well, is it a fetish to salivate for blondes, or redheads? Don't think so.
I just know that since I was a young guy, Asian girls have been my fancy, and to quote the late, great John Candy, in, I believe, SPLASH, "when something works for me, I stick with it."
Not to mention, in the hobby world, as CDL said, what looks, what service, what beauty, all for an avg $250 here in LA! How the hell can you beat it when a gorgeous young thing lets you splooge on her lips and smiles while you're doing it!
