I think that G at the standard ($2) places might be VERY low probability.

Then there are some upscale ($3 to $6) AMPs that do more screening and some, by personal choice, allow G.

Then there are the indy K-girls. They do what they want for the amount they set.

If you do a VIP search for NYC, anal, Asian you'll get a couple of hits. There are more whose Profiles say "No" to anal but whose reviews read otherwise.

In the meantime, there are also NYC or touring Asians who aren't K but from other countries who also do G. First two that come to mind are Tattooed Asian Kim and -- oops -- a VN girl who is now LV based, visits NY but who is banned from TER so I can't name her.
