Some girls are relatively new and you could ask the mamasan/papasan for one that hasn’t been working long.
If you’re vacationing I recommend it as a “try it once” type of thing.
You don’t want them getting involved because they will try to take you somewhere else or get a commission for taking you and you’ll be overcharged. You don’t want them to know that you are looking for a soapy massage in Bangkok!
In the beginning, there are two types of girls you want to focus on at the soapies in Bangkok.
Getting pampered Thai style – A Typical Soapy Encounter: There is a flashing neon sign in front of a large, classy building. A papasan (male host/manager) or mamasan (female host/manager) greets you and helps as you browse around.
You take your time and choose your girl for the evening.
The obvious main difference between these two is going to be looks and –you guessed it- price.
