Lots of good comments. A few things to add.
At the high volume places the girls make $30K - $50K per month. Some work 6 months a year and others 12 months a year. You would be shocked at how many millionaires are working at the AMPs - I know a lot. Most of these girls have more money than the fuckers walking in the door and laugh at how poor the clients are. The exceptions are the girls with drug and spending problems but less of these than you might think.
As stated before, most of the Asian girls want to take care of their family and kids - no different than us. Quite a few have kids but fewer are married. Almost all of them have learned that they can't depend upon a man to support them. If they want, they have to be willing to go get it. Outside of work most are completely normal but are very focused on making money - if they weren't then they would have quit already. Very few of you guys can replace the $300K - 500K a year these girls make tax free and thus don't really have a chance. Most of the girls own multiple houses with usually one in Korea, China, etc. and one in the US if they have green card/US citizenship.
Some of the girls have a definitive plan to make X amount of money or work Y amount of time and then quit. Others become addicted to making money and their happiness is tied to the amount of money in their overseas and US checking accounts.
I've been told 30-40% of the guys are able to fuck OK (i.e. the girls would say your cock works), ~10% of the guys are able to kiss in a way that doesn't turn off the girl, and only about 5% can lick a pussy OK. As said before 99% of the sex is acting on their part. Working girls know that their longevity is based on 1) Being pretty 2) Looking young 3) Service and 4) Talking in that order. I've seen guys list the age of a girl as 27 when I know she is 44
If you are going to date an AMP girl you had better be wealthy enough they feel secure about not working and willing to spend a lot of money on therapy (for her and you).
