Everyone has his/her own definition of that term.  And I don't necessarily limit myself to seeing only "low volume" providers.

I do expect that the provider is excited and ready for the session.  If the provider is acting or just going through the motions, that's the last time I'll ever see her.

If I just wanted to see a hot girl who I could get off with, there are plenty of choices.  The reason I personally use TER and conduct my own due diligence is because I wanna make sure that she and I connect.  Girls who I have seen and connected with are the ones that I keep seeing again and again.  The ones that seemed to be going through the motions...well, that's just not for me.

Call me weird.  I actually like to know that the girl is enjoying the sex as well as the money.
