Stone Bridge Horse

Oh wow, don't mean to be a spoiler but I would never use any agencies, especially http://www.chinagayescort.com
 
It is essentially just answering the phone, hook you up with an independent escort that you can already directly contact, and charge you a mark up for their "services" that can sometimes double what you should be paying.
 
This is how they work, at least in Hong Kong - most of the guys you see on the pages are Mainland Chinese men. They can only stay in Hong Kong on a visa for usually no more than 2 weeks at a time. They are therefore highly mobile and would like to take as many clients as possible during their stay.
 
Most of them advertise independently in here: http://www.gayhk.com , which is fill with banner ads that will lead you to their pages where they show their photos and contact info. They are also very active on any number of online dating apps like Grindr, etc., I will teach you how to find them there below.
 
So essentially the "agencies" are adding no value at all. The worst part though is that the photos and info are misleading, as many of the escorts being shown on the pages are actually not there or no longer working or simply just other people's photos. It gives the impression that they have many choices, but in reality only a handful are actually in town (because of the mobile nature of their stays). So when you call they will try to talk you into hiring the ones that are actually there and the ones that are more cooperative with them.
 
The only benefit they provide is probably translation, as this site is obviously catering to non-Chinese speakers. No locals or other regional Chinese would ever use this one. But I know many experienced travellers have been able to negotiate using online translation and texting.
 
You can find out how much this site will ask, and compare that to the going rate of an incall as low as HK$800 to maybe up to HK$1,200-1,500 if you contact them directly. A note though - I won't pay anything more than HK$1,000, as their fee is often negotiable, depending on busy they are.
 
I would also be very careful with photos - many of their photos are so outdated that some could be more than a decade old. Whether it's through a middleman or direct, insist on asking for recent non-photoshopped photos. Or ask them to just take one on the spot and send it over the phone. Don't believe in anything you see online.
 
While there are definitely good quality guys with the looks, body and attitudes, my take is that at least 2/3 of them are there to make a quick buck and they won't mind cheating by using doctored or old photos, sometimes even fake ones to lure you in.
 
Also NEVER give them the room number to go meet you directly, because if the photos are fake you would have a hard time getting rid of them. Meet them in the lobby or at the entrance. They don't know how you look. If they look totally different, just run. If they insist on going up to the room it is also a sign that they're likely to be dubious.
 
That's the situation with hiring Mainland Chinese escorts active in Hong Kong. I suspect the same with their listings within China. Note also the going rate is also similar, like around as low as RMB600 to anything between RMB1,000-1,500. Again, IMO, nothing in China worth more than RMB1K, or USD200.
 
Not that they're bad looking. From my experiences the services are very rarely as professional as those in US and Europe. The attitude is more about the hustle than anything. You can tip if they are really good, but you can never ask them to charge less if the services are lousy.
 
Back to Hong Kong. So how to find escorts on Grindr, etc.? Most of them are active in the city center, mainly in the area between Tsim Sha Tsui and Jordan subway (MTR) station in Kowloon. If you're traveling its likely that you will be passing through this area.
 
Actually you will be able to see not just Mainland Chinese, but also escorts from Thailand, other Asian countries and an increasing number of Western ones. However, for the Western ones you can just go to the usual sites like rent.men to find them.
 
There are also many local Hong Kong Chinese working as "masseurs". Unlike the Mainland Chinese and other nationals they are more shy and won't advertise publicly. Some do on rent.men, Grindr, etc but most are working in "spas" or "massage parlours".
 
The locals usually go there to get a rub down followed by happy ending. Those places are also advertised on http://www.gayhk.com
 
I hope it's useful. But really, stay away from http://www.chinagayescort.com
