What is the most alluring attraction to an upscale provider?

I definitely enjoy a good conversation. I am just new to all this and have been taking my time. I am not trying to rush into anything.

It is hard to say who is upscale. I have played in the hobby for many years and you cannot call upscale based on 200 or 400. Most of the top providers I have met were in the 200 range and were top in looks, menu, passion, and just fun to be with.
Each client and provider is different so each of us are looking for something different.
For my it is looks, body type, enjoys meeting new people and laughs and has fun while doing the sex.
