Are you a girl or boy? Are you attractive or not?
Those are very important factors. If you're a girl, as long as you're willing to offer sex, the LAO WAI will happily take you, and wouldn't mind your poor English. There is not much communication needed anyways. It's the cheapest way for LAO WAI to get some sex. Though the sex is not as good, but what the heck, it costs almost nothing, right?
But you also can't be too ugly?! ....
Good Luck !
