What all's involved?
Is it like GFE--a term that means different things to different people?
Is rimming always offered?
Is it acceptable to call yourself PSE as a way of letting clients know you offer Greek (without offering certain other activities commonly seen in porn)?

This isn't explained in the newbie manual...
Thanks!

because like GFE and other acronyms, it aint necessarily so.

One hard and fast rule for clients -

check her *reviews*

for providers I would say that if you offer the acronyms listed in the subject line, you're good to go.

BTW many ladies offer GFE (everything but the tushie) and PSE as an upgrade for an added 1 to 1.5 or so.....

Hmmm...I've been offering these acronyms for GFE prices....
I can't believe it, given my line of work, but I've just been giving it away!

PSE means different things to different people, but I don't know of any Provider who's considered GFE who charges extra for any of these items except for greek (and some don't charge extra for that). Of course, not all of them offer CIM, but the others are standard.

kissing and lots of foreplay.  I might add the Russian element or a pearl necklace and/or facial from time to time.
