141 is an excellent place to find providers. However, one thing I have learned how to do is find actual business women looking to get laid too. 9 times out of 10 they are relatively young and good looking (the international travel has something to do with it I think). In HK there are a lot of them. They generally stick to the hotel bars, but they are there. Best part is they are free! You can expect Euro chicks, American, and Asian. Nice thing is, sometimes you can go back to THEIR rooms. I realize this is a provider site, but sometimes this is a nice change/challenge. This is really the only place they will let loose (for same reason we do too). The business women from Singapore really let loose, as do the business women from the UK. Spanish women tend to be a bit more reserved and look for romance, French women can be boring. Americans are cautious, but can be quite fun after a brief warming up period. There are quite a few more from Singapore than anywhere else so you can still get your Asian craving easily enough. The Singapore women are always impeccably groomed as well (up top as well as below). The ting I have found is just tell them up front what i am looking for (one night stand, no strings just fun) and almost always they want the same thing. If you want to see them again trade private email or your Hong Kong or China mobile number if you have one.
For me the HK provider scene is a bit scary because of the frequency of travelers that pass thru even though I am covered every time. Some of these girls will do up to 10 to 15 a night. The other part that is not so safe is the Triad presence that is always around. If you go to Mong Kok you will definitely see it. You have to be on your toes at all times.
