In My Not So Humble Opinion:
To answer your second question first - I have never nor will I ever willing book a TS provider due to a complete lack of interest. I also admit being highly suspicious of any reviewer who rates the appearance of a TS higher than a woman. "To each his own", but just not me.
Turn Ons:
Like any man I'm attracted by certain physical characteristics. Generally speaking, I like natural looking T&A curves (man made or not), clear skin, and if faces are shown - bright eyes and sincere smile;
A woman who has a Board presence that's witty, wise, and relatively grammatically correct. Common interests are welcome - though I'm looking for a date more than a SO. Still, chemistry makes for a better time by all.;
A woman who can 'go with the flow'.... allow me to lead but also use/instruct me to get herself some measure of sexual satisfaction (My ego is boosted most by that glow a woman gets, the kind not readily faked).
Basically, I'm the Johnny Carson joke about "Sex is 90% mental, but boy does that other 10% feel really good" kind of man.
Turn-offs:
Providers who moan like Sally/Meg Ryan when you tough her leg;
Heavy make-up that obscures any natural beauty;
Providers who have a good online presence because their handlers/assistants write their posts for them. In these cases, I often think that I had rather seen the assistant;
Lie about age (do not claim to be 24 in your ads and websites for 10 years, some of us have been around a while);
Being called Daddy by someone my daughter's age. Sure I like a young coed who might be "my daughter's roommate who keeps me company until my daughter comes back from studying at the library (hope we don't get caught)" kind of fantasy, but being called Daddy makes it a bit too incestuous sounding;
Perfect Date: There's not just one. What I consider "perfect" with one woman doesn't necessarily apply to anyone else.
You got a whole nickel's worth of my mind today folks,
