Singapore and Sex run hot and cold for the sex industry, there is always action there, the problem is where is it and how much is there. I have gone to Singapore when the place is absolutely over run with Sexy women from all over the world and the prices Considering that it is Singapore are fairly reasonable and then you might go 6 moths later when the police and immigration are activity clamping down and the Sexy Asian women from places like Thailand Vietnam Philippines and exotics from places like Chile and Costa Rica Colombia are gone and all that is on offer is very old and worn out Chinese women who speak just enough English to ask for stupid money if you want to hire them as escorts.
In Singapore you can always go to the houses but be prepared to spend a lot of money for a quality experience. Geylang area between Geylang Streets 8 through 22 there are numerous houses to chose from set up with little car ports as it caters to the richer segment of Singapore Society. If you are taking the train get off at Green Line at EW9 Aljunied. http://g.co/maps/jwwzs

Singapore Street walkers are everywhere in this Geylang area and there are lots of little restaurants and outdoor cafes where you can sit and drink the Sweet coffee, Sweet Tea or Beer and watch the ladies in action. It is a little weird sometimes there will be all sorts of people standing around mostly Indian men and when they see you engaging with a lady they want to listen in to the details I believe mostly so they can see what the prevailing rate is.
The other area where you can go for women of negotiable virtue is the Orchard Road area. Be prepared when you go there to spend a lot of money as Orchard Road is a very expensive area of Singapore with lots of high end shops malls restaurants and other entertainments. This is the area that a lot of tourists are directed at by the touts as they will get the same percentages but the rates are higher so they make more money.
