First date: Feel the guy out, by the end we've learned what he likes

Second date: Jump on him and do exactly what we know he wants...

overall I'm a believer in the law of diminishing returns.

the second date is better, and the third really rocks.

Then, it is hoped that a sort of plateau is reached, but there will always be some up and down.

Good providers learn new ways to keep guys happy and experiment from time to time, then go back to the classics from time to time.

Think along the lines of a performer who holds up to the test of time over decades by reinventing themselves, and staying current with trends.

We have money to motivate us, but other than that...gets old seeing the same people over and over. I guess I am like a guy in that respect, because even though I am being paid, I do bore of certain people.

Distance makes the heart (well... you know what I mean) grow fonder.

...with the same provider in as many weeks.  Each time gets better.  First time was a fast and furious fuck fest.  Second was more of a gfe/civvie date with fun before and after dinner.  Third was like your steady gf coming over to spend the night...cuddling, massaging, slow sensuous sex...more cuddling, etc.  Fourth...we didn't leave the bedroom...more fast and furious....

I'm in the camp of repeat and repeat often when you find the right provider.

Typically the first is full of figuring out what's permissible, nerves.  Second or third is pretty darn good.  Frequent repeats seem to fall off.  More random return visits are higher grade.  I like to rotate among a small number of Favs.  It's good as prescreened...  if one doesn't work out, there's another to try.
That said, I'm sunk right now.  2 retired (one has a day job now so very little availability & UTR)(another has gone off the grid.  I saw her right before her site went down & she'd been hospitalized).  My longest Fav is no longer local...    
I should have been replacing but I just didn't...
