I was giving this whole issue of the GFE experience some thought while hanging out at a local strip club yesterday (gotta do something while waiting for my quarterly business trip to Vancouver and visiting your fine mp's!).
Anyway, whether we are visiting an SP at a strip club, an mp, or an escort, we are basically asking for some level of service. I part with X dollars, she provides a service. Point is, whether I just bought a dance at the sc or a couple of hours of companionship with specific services included, the lady can chose to provide them mechanically or can provide them while pretending that we are friends.
Arguably, a lady who talks to me, makes me feel more comfortable, who plays the game that she is enjoying the experience, who makes the most of our few minutes or an hour, is more important in my book than whether the BJ is BB or not. Heck, I had a GFE with a lap dancer yesterday... it certainly wasn't FS, but she did provide a value added service that enhansed the pleasure. Probably somewhere in the definition of GFE is providing services at the high end of what we paid for, rather than the bare minimum. Remember, a lot of sex is in our brain -- Playing the part of my GF while providing X service is worth more to me than simply having an SP perform a service.
The thrill is in the chase, not in the purchase of services.
