What is the definition of this Greek service?
I would also like to know what usually comes with a GFE experience?
Thanks

Greek is anal sex.A girlfriend experience varies from lady to lady and may involve light kissing or deep french kissing.It could involve a massage or a striptease.It could involve a BBBJ or a CIM.Basically,it's a more personal experience than just a wham,bam thank-you ma'am.Hope this answered your question.

. . . a GFE experience means girlfriend experience which typically means BBBJ, DFK, FS, some emotional intimacy, light conversation, non-rushed, etc.

What you'd expect from a woman who was your actual girlfriend, I can't imagine it any other way.

Misty nailed it perfectly.
Unfortunatly it's the most abused term in the hobby. Since it's what most guys are looking for, most providers claim to be it.
