I can break it down to a far simpler psychometric algorithm for any wg I would like to meet - it goes thus :
You've agreed to see me & have taken my money for (insert time here) hrs.
Now pretend that you want me to fuck you.
I would agree with that if the girls weren't human, they aren't machines or robots and are bound to be affected by all sorts of factors. I have just over one year's experience, in that time I have seen dozens of different girls, and seen some multiple times. I have seen girls who have had bad reviews on here and had a great time, I have seen the same girl and had a completley different expereience with her than a previous time.
I think nearly all of them pass the test (just in some cases) of pretending to want to fuck me. But the one's I go back to are the ones who give an hour of enthusiatic fun.
I love the excitment of not knowing and finding little gems, that make up for the mediocre.
