xTube.com is a tube site with a little bit of a difference: it has a lot of amateur material and because of this, people see it as being more of a community than a place to just get off. I mean, of course, if you just wanna wank and flee you're free to do so, but you'll sure as hell be encouraged to sign up and leave a comment!
There are currently just shy of 20,000 scenes if you search 'Asian' on the site and specify you're a guy looking for gay material. Be warned ahead of time: a number of these are of guys jerking themselves off and filming it for you to enjoy. Now naturally, you might be hella into that, but others may want to see more fucking, in which case, I suggest you refine your search a little.
So yeah, while xTube.com isn't the most standard of tube sites, I think it has you covered when it comes to gay Asian porn videos - ESPECIALLY amateur ones. Head on over and see for yourself: it's not at all bad.
