a GFE gal will kiss, and more or less behave like a girl friend.  The sex will be nice not not raunchy.

PSE, on the other hand, will be more like what you would see on a porn video, and you can do stuff like cum on her face.  Also, for the most part, PSE denotes that anal sex is offered.

Being relatively new to this hobby, what is the difference between a GFE experience and a PSE experience?  What more comes with a PSE experience?

from the way I understand it, a GFE will clean you off nicely when all is said and done and a PSE will leave you to clean up your own mess.

With PSE the mess is supposed to be on or in them (cim, cof, etc.). Greek is usually offered as well, not always, but often. Thats seems to be the difference, although some GFE providers do some or all of these. Correct me if I am wrong(Someone will I am sure).

GFE is supposed to include BBBJ.  Also true of PSE, of course, so it's not a difference.  But, if there's not BBBJ it ain't GFE.  GFE also should include DATY.

You may have a hybrid where there's plenty of kissing, the sex is great and it always ends with cumming in her mouth or kitty.

While it is true that sex in porn flicks is largely uncovered, this is not what is meant by "Porn Star Experience." At least, this is not how the majority of providers who advertise PSE sessions are intending the term to be heard...

If you see, for example, GFE $300, PSE $400, the extra $100 is for greek, unusual fetishes and/or or role play. A PSE session usually includes all GFE activities (kissing, daty, bbbj) PLUS greek and POSSIBLY cof, cim, or squirting. Also, PSE denotes a different mood than GFE...while GFE sessions may include wine-sipping, cuddling and chatting, PSE sessions are typically characterized by balls-to-the-walls sex, multiple positions, rampant dirty talk.

This is what I have seen to be characteristic of the escort industry. No first-hand knowledge of the porn industry, or of porn stars who also escort.

To make it really easy for you: the most common meaning, when you see it in an ad or on a site: PSE = greek. Simple.

You're much better off reading the juicy details of reviews.  Everyone has their own definition of these terms. Don't take pse/gfe in a ladies ad at face value.
