I've been meaning to start this thread for a while, and Tarrus' recent question (what does GFE mean exactly?), along with the responses it drew, gave me the final push. I'm starting a new thread as I think it is more useful for TAG'ers if the subject accurately reflects the content. For reference, here's the original thread: http://forum.tokyoadultguide.com/escort-service-reviews/5844-review-yuko-am.html The question made me think of a line from a Lewis Carroll story, where Humpty Dumpty says something like "when I use a word, it means exactly what I mean it to mean, no more and no less". It also makes me think of the American judge who said that he couldn't precisely define pornography, but he knows it when he sees it. As meiji points out, there is no standard definition, so it means different things to different people. But there must be some overlap in our definitions, or else we wouldn't be able to communicate using the term, so maybe we can tease out the overlap. I think Tarrus hinted at the answer (at least, for me) when he said "it has always been better with the girlfriend". Why? I think it's because she is personally invested in the act, it is a shared experience, she wants to be there, and she is enjoying it. Of course, for any given couple, several of these assertions could prove to be wrong, but I think this captures the general case. Of course, p4p providers are, by definition, different than the girlfriend we are describing here, although I think the line could blur if you were to accumulate enough history with the same provider. However, let's set that aside for now. In a previous review, I said that a particular girl provides the quintessential GFE. What I meant is that it feels like she really likes me, and like she really enjoys what we are doing together. I've also said that it doesn't matter if this is an act, because it is indistinguishable (for me) from the real thing. To me, that defines GFE.
