Lol love some of the replies here
I actually discussed this with a regular client at the end of one of our meetings as he said although he loved a sensual meeting with kissing, cuddling etc he didn't see it as a GFE and he would rather look at it as an Illicit Affair Experience as his girlfriend was a nag lol !
I thought it was a good acronym so we had a laugh about it and I asked if I could use it on my profile .....so I took it on board and part of my profile offers an IAE (Illicit Affair Experience) tongue in cheek really
As an acronym I don't think it will really take off but I could see his reasoning
