I think it has it's own term...
Greek, Anal, Backdoor...
I do not believe they really fall under gfe nor pse unless other
activities are involved...
GFE Girl Friend Experience. Affection oriented escort.
But... typically means a lady who offers Daty, Dfk And BBBJ when
the guys break it down in reviews or services offered...

I could consider myself a gfe provider, love to snuggle, lay in bed naked, chat be affectionate and sensual and yes I love greek and offer it (most girlfriends don't lol from what I hear) but being I do not offer the 3 services listed above, I would instantly be called out for false advertising in reviews for not being gfe... The definition has been left open to kinda run in your own direction with. Every body has their own term but when it comes down to it, most consider gfe as listed above and pse to involve cim along with pussy to mouth, ass to pussy, ass to mouth dirty talk and everything else we all love to watch in our dirty nasty pornos
