While my experience is limited (though I haven't reviewed most of it), it seems while many providers describe themselves as "GFE",  it doesn't seem to mean anything much of the time. Isn't the offer of GFE predicted on not only the allowance for specific acts (such as DFK), but also a warmer, more inviting atmosphere that is friendly and comfortable?  One might say it is meant to be like an 'experience with a girlfriend'.
I'm wondering what providers and hobbyists alike specifically consider GFE to mean, and how it differs from non-GFE.

Our mind is constantly labeling, judging, analyzing, evaluating, and comparing each person we come into contact with, including all life forms and things that exist.  Such is our mind’s conditioning. It is nothing but mind created false ego. In every profession, including providing, those who are exceptionally good at what they do may be completely or largely free of ego while performing their work. They may not know it, but their work has become a spiritual practice. Most of them are present while they do their work and fall back into relative unconsciousness in their private life. Those who perform their work admirably, are fully responding to whatever the moment requires of them. They are one with what they do, one with the Now, one with the people or the task they serve. The influence such people have upon others goes far beyond the function they perform. Theybring about a lessening of the ego in everyone who comes into contact with them. Even people with heavy egos sometimes begin to relax, let down their guard, and stop playing their roles when they interact with them. This, btw, applies to all professions.

It's basically a blanket term for a lady who's willing to kiss and act affectionately. Each lady is going to be at least a little bit different in her approach (as would any real-life girlfriend). You'll just have to shop around and figure out who meets fulfills what *you* are looking for.

Cocktail-party is on to it, I think. To me if you are with someone who offers GFE than for that hour it is like you are with someone who is your girlfriend. Now, some girlfriends do CIM and some don't; some rim and some don't, etc. And you might or might not choose to keep them as your girlfriend based on those factors as well as  others.

It ain't GFE if she hasn't tossed your clothes out the window and kicked you out the door. Neither my ex-girlfriends nor my wife (now ex) had ever given me a blowjob.

Im versatile to Gfe and Pse but I prefer Gfe because it's more intimate and relaxing. I think it's fine to ask if a provider offers Gfe but you can usually tell how genuine their answer is based on reviews. What I do differently is try to make a connection with the man I'm with and let things flow naturally from there. Men want a feminine touch and to feel appreciated and attracted to. Gfe to me is flirting, eye contact, DFK, holding each other and essentially making love to the other person. Making the man feel appreciated and that you are enjoying his company as well. It's not something that can be forced or it will feel awkward for both parties.
