Before I book, I have to like the provider's body and what I can tell of her face through the blurring. When I arrive, I have to like both.
The second is personality, which shows itself within a minute of the first meeting. We must get along well, converse easily, seem to enjoy each other's company.
Third is obviously performance. I need a very good blowjob, although if it's someone I'm going to see regularly, I can be hopeful I can teach her to do what I like. I don't like fake noises. I want someone who will let me know when I'm doing something right, and suggest what I should do.
For me to become a regular, there has to be some spark, something different about her that just draws me in. That's only happened twice. The first time I kept seeing a provider again and again until she retired. It happened just three months ago with another, and I've been seeing her for four hours every three weeks (too long a drive to just spend an hour or two). I knew within the first half hour with her that I'd be seeing her as often as I could.
I'm delighted to find someone who makes me want to be a regular, as I will want to explore a lot with her.
