What is it? New to this and curious

For me, I offer cim, cof, and porn star energy in a gfe, but no greek or rimming. PSE is usually as Julia stated...more high energy over the top, and not as many water breaks lol.

meaningless unless you read the reviews as LR mentioned. Do not get hung up on any terms in the hobby, as there are many, one of my favs is VIP escort.  Nothing replaces good old research.   So get VIP membership, learn how to use the TER review search  feature and you'll do fine.

I guess that is part of the PSE, but again, as others have mentioned, read reviews and read her rules and website.
Not all providers allow you to film the session and it usually costs a few hundred extra.
Again, read reviews, read her site, ask her, etc.

Many guys actually believe that any woman advertising or pse allows the above...far from the case.

There is no answer and no definition of what one is versus the other.

Instead of trying to define GFE vs. PSE as a list of acronyms that you can check off or a formula such as PSE = GFE + anal, just read a girl's reviews and get an idea of what she offers.

With GFE you beg for greek.

With PSE, she begs for it.
