Hey there my little fallen luv muffin!
My personal experience, and that of those that I have talked to, is that gay interracial sites just don't perform all that well. To be honest even strictly "ebony" don't perform nearly as well as "non-ebony" sites do.
I don't mean to come across as prejudice in any way shape or form, it's simply a matter of the dollars and cents of it all.
I'm sure others that run these sites will post after me saying that I'm full of shit and have no idea wtf I'm talking about, but if I were you I wouldn't bother with the interracial gay stuff.
As far as strictly non-white gay sites go, Gay Asian performs pretty damn good, and SIGNIFICANTLY better than "ebony".
We have

Best of Luck!
