GFE = Girl Friend Experience
I never had a Girlfriend who wouldn't kiss (DFK) me passionately. However, there are a couple of xGF's that wouldn't let me round 3rd base.
The illusion of passion (IOP) is therefore critical for a GFE. The illusion that you are enjoying being with your client and that the donation doesn't have anything to do with it. The GFE provider "provides" the illusion that convinces her client she really has the hots for him. (Even though we both really know it's a business transaction.)
For most guys it's near impossible to feel the IOP without quality kissing (DFK & LFK).
Hence, good acting skills help.
Great GFE ladies are hard to find. PSE (Porn Star Experience) providers are dime a dozen. Dannie is one of the very rare ones that can do both to near perfection.
