I gotta agree with vanperb, I've had a couple girls I regular back in the day, mostly older girls from HK who came here to make a quick buck, support family back home, pay off debt and move on.
One of them said they were willing to stay if I wanted to pursue something serious, but realistically the cost of living here with her skill set (or lack of) wasn't great and I didn't want her to be a mamasan trying to cost of living or taxing myself heavily financially to support her.
The younger Asian girls here mostly stay short term to earn funds for school or whatever and to be independent. Once they've achieved their goal or met someone they usually disappear, plus considering they're young there are far better opportunities doing civilian jobs without over wearing their bodies.
From all the years I've been on this forum, the ones that stay in the industry too long become jaded, are shells of their former selves, or try to move on to be mamasans but continue to see regulars because their girls can't do what the guys expect.
Generally, any girl you meet in this hobby has an expiration date. Like even the legends that a lot of the guys rave about will eventually leave as they've achieved their goals and don't need the wear and tear anymore.
