I understand both sides of the argument on what GFE could be. I mean if you go strickly on the words themselves, there is a debate to interpretation. And yes going trough acronymes do not guarentee pleasure or a good experience.
That said, using the universal code for GFE being BBBJ, Kissing and Daty just make it so much easier to read ads or inquire without wasting anybody's time. Personally i can adapt to different style of sessions. I can enjoy a more "PSE aproach" as in lets bang, fake moan, dirty talk etc, but i can also enjoy a sensual more warm session. I try to gauge a bit how the provider behave and see where it go. Im adaptive on that side. BUT the BASE acronymes are ...well the base, for me. I have no interest in a CBJ and a session without AT LEAST some light kissing would feel weird. Its what make me hard and THEN i pull my pants down lol. I need a bit of foreplay. Even a PSE session i want that. if you ever looked at a Brazzer skit and scene, most of them start by kissing as well, PSE or not lol.
So basically i like to make sure an indy or agency is "GFE" before wasting my and her time contacting them. PSE on the other hand is much more open to interpretation. But for the years i been doing this in Montreal GFE always related to the 3 base services while someone that would not be GFE would list themselves as "providing full service" or in french "le service complet". Some also use "safe gfe" maybe because they offer as some of you point out, a more girlfriend attitude but without the acronyme. I think everyone that see "Safe-GFE" knows what it mean as well so im fine with it to differenciate.
I know some providers will probably read this and say "im sure i could make you leave very happy even with a CBJ". Yes its possible. But considering the frequency i meet and the options in Montreal, i rather go for what i enjoy the most directly. If i was booking once a week, i would surely squeeze some non-gfe encounters in there sometimes
