I came to the realization that one major reason why gaysians are the lesser sought after among other gays is because of PORN. Thats right, porn. Check out any major studio, xtube, rockettube, ect. Whatever asian porn you may find on there isn't so great. Even myself, being an asian who likes other asian, often gets deflated at the sight of gaysian porn. 
Asian girls are prized in the str8 world because of all those great pornos of young hot asian chicks getting banged by big dicked white dudes. Those implant a fantasy in the viewers and they carry that with them to their friends and that notion can spread like wildfire.
The biggest barrier for gaysian americans today is the fact that there is no studio putting out stuff like corbin fisher or 
Sean Cody but with asian guys. Us gaysians are left with imported porn, with effeminate skinny boys who are 4months overdue for a haircut, or some "str8" jock who is getting fucked by a pink vibrator and then by someone wearing swimming goggles. 
Point is, gaysians here in America have never been sexualized like their female counterparts. And that results in a low rating on the desirability scale.
