Maybe it's just the romantic in me, but I think of GFE as being just that.....something like being with a girlfriend. Kissing, (preferably DFK over just LFK), BJ (Preferably BBBJ over CBJ), and multiple positions and shots. I guess making out like two teen-agers who know mom and dad will be home in an hour may describe it well

But, like you, I may have a different definition and I hate to put a label on it. I try to provide a "BFE" to the lady I see, so that really makes the GFE just come along naturally. I show up dressed decent, freshly showered, and a fresh mouth. That alone should encourage a more "friendly" experience. GFE just may involve more than just the sex part. I think even conversation and foreplay will be part of a GFE.
Here is what I think GFE is not.....rushed, emotionless (even if faked), minimal contact, mechanical.
I'm a pleaser, so its a major turn-off if I feel that the lady is simply going through the motions. I can go through the motions with my hand. GFE should have some kind of a connection during our time together. Does this help at all??
