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.
