Having now attained the grand old age of 70 (though I don't look at day over 65 lol), and given that most of the SP's I see are from HPL and are usually not much more than 20 years old, I would have to say that most of the time the girl looks disappointed or at least a bit surprised when I enter the room for the first time.
On the plus side I'm a charming old guy, with a good sense of humour, and am clean and respectful. In some cases that has been enough to overcome the the sp's initial reaction, and we actually have an enjoyable time, with quite often an invitation from the lady involved at the end of the session that she hopes to see me again & soon. Good PR and marketing on her part I know, but at this point I feel I can sense an honest personality "clicK' when it happens. Also, I'm pretty good at daty, often much to the sp's surprise.
Lastly, I don't push for lfk/dfk unless the girl actually moves towards me for it. It grosses me out a bit when I see some handsome but aging movie star on the big screen kissing a much younger woman, and I ain't no movie star, so I don't want to force that on a girl who might be similarly repulsed. That said, if she really wants to kiss me who am I to say no?
Obviously if there was no "click" I don't repeat. First sessions are always 30 minutes to see how it goes. Repeats usually 45 minutes when I am confident that she will likely enjoy the session as well.
Anyways, for those with whom I do click on at least some level, when I see them again they are usually all smiles and hugs when they see it's me at the door.
Fwiw,
