The term GFE in lpin is a crock of shit.
Its code for I am going to charge you more money. Some ladies won't kiss clients for various reasons some will only do it with selected clients if the right person is in front of them at the moment and they are in the right mood.
That is fine your the one selling the services. Charge what you want do certain things with client A but not B or C.
Its cool. But most clients booking the so called GFE party will expect to be able to kiss you.
So rather then coming up with your own creative definition of GFE and not allowing certain activities that most clients will assume is part of the so called GFE party.
Just be strait up yes I will kiss or no I don't yes I allow daty or something not really GFE but more of a speciality party like a trip to Greece. Just be straight up if you want kissing yes I will do it but that is in my priemum package it will cost you a little more than just standard sex. Or no sorry I don't do that with my clients. At this point you two will either agree on something understanding of the rules of the moment or contract talks will end and you go your separate ways. Freeing you both up to find another dance partner.
