I`ve perceived that I have met both.
There is something that I can read in a true cold pro. She tells me what she thinks I want to hear. Is she really happy to see me? No, not really....she only wishes I had ten times more money. I can detect a thinly veiled contempt for me. The kicker is the clock control and the cash register control. I can twist her body anyway I want on the clock but the counter must be ticking. She has two orgasms; one when I pay and one when I leave. She wants that much money to fly to NYC with me?!?!...ha, no way!
The amateur is more sensitive. She can be a mixture of guarded, careful sincerity. I can tell that she appreciates my company, (I think it shows that I`m happy to offset the living expenses of an honest, health minded, attractive, good natured, sensual woman that is 20 years younger than me and does not have a high paying job). These are girls I never want to damage, they deserve friendship & kindness.
Then there`s the screwed up pro and semi-pro that does anything to feed a bunch of problems. I don`t need to go into that.
