Do some research on this board and you'll learn all about them.

Also, be sure to read the Self Help Manual that is linked on this page (Look for the red and white life preserver.)

It will also have info on screening sites as well as lots of information about the hobby and how to use TER.

Welcome and best wishes.

unless you want to see providers who don't screen or ask for references. Then it's a total crap shoot as what to expect in the way of a session. Just the way it is. BTW, the previous post asked a question about references. You should check the board before you post to see if your question has been asked before. There really isn't a newbie question that hasn't been asked.
