a massage will vary from location to location... what you get for your money, how good it is, etc.  there is a MP review section here that should help you figure out the lingo...
an escort service is similar in the iffiness of it all, but a *bit* more can be assumed.  
they will also cost more.

do your research here, learn the lingo and fit that in with what you are Expecting from your encounter.
Then decide where to spend your money.
my only hint/tip for you is that when it comes to MP, Theraputic Massage = Actually a massage  

TER is an excellent tool. learn how to use it and you wont ever be disappointed.

have fun and play safe,
Nicole

All Vips have this option.
