OK, maybe my first comment was a bit snarky.  It was meant to be.  Here's what I recommend:  Look through the ads, look through the reviews, use google.  Then, make phone calls.  Talk to them.  If you get a good vibe, make an appointment.  Often, you will have to vist a provider multiple times to be offered the full menu.  Massage providers are just like anyone else: if there is a personal connection, you are likely to be offered more.  YMMV.  It also helps if you are attractive and well endowed as I am.  One of the great pleasures of the hobby is never quite knowing what you'll get.  I recently found myself in my session with a well known, strictly therapeutic provider who had done absolutely nothing erotic during my first two sessions.  Frankly, I wasn't expecting much other than a very good massage when I made a third appointment.  During out third session she became very hands on almost from the beginning.  Within ten minutes, she was bent over the table, leggings down, panties to the side.  My point is enjoy the experience, enjoy the moment, enjoy the hobby.  You never know what might happen.  And, no, I will not reveal who the provider is.
