All righty Jimbo, I'll take a swing.
1) What's an escort?
Anyone who will
spend time with you for money is an escort. What happens when you're together is completely up in the air, and to some extent locale-specific. As an example, many agencies out west have a "door fee" that gets the girl to your door. At which point you then negotiate with the lady fees for services. If you can't agree on a pay schedule, she leaves and you lose the "door fee." Yep, if they tried that shit down here in God's Country, we'd raise 10 kinds of hell, but it's flipping SOP in some places.
2) What is No-GFE?
Again, this means all kinds of things to different people, but in general it means expect everything to be translated and kissing is hit-or-miss. Some girls take it to the extreme, and won't have any type of fluid exchange (sometimes abbreviated as NO-EX or NOEX).
NO-EX is basically Lot Lizard service - expect a nut, but nothing else - no convo, no nothing!
Some girls also use the terms GFE-Safe of GFE-Lite which means kissing and usually DATY are on the table, but the French and FS are always translated. There are a lot of great providers that fall into this category - exceptional providers who really do provide a girlfriend experience, just with a CBJ. And as a warning, some girls advertise as GFE when they are really GFE-Lite. This is (in my experience) much more common up north and out west, where any type of uncovered service is the exception, not the norm and GFE means kissing and conversation is available.
3) What does YMMV really mean?
YMMV has 2 definitions. When a guy says it, he means he got certain services but
YOU MAY NOT. An example of this is a provider that gives better service or a wider menu once she's seen you a few times and gets more comfortable with you. I have a review on the books where I received untranslated French from a girl even though she advertises as GFE-Safe. Why did I get it and you didn't (or vice versa)? Who the hell knows?
However, if a girl advertises as YMMV or her reviews are hit-or-miss, it usually means that she only gives good service with someone that she "clicks with" Maybe she's better with guys she finds attractive or maybe it's younger guys - whatever.
However, it's always a cop-out that means, "My attitude, menu and/or service level may vary from date to date." In other words, don't expect anything other than a nut. YMMV and NO-GFE go hand-in-hand. You may get GFE 1x out of 10, but brother, you better not expect it...
Stanky's bottom-line: I won't see a YMMV girl, because who wants to gamble with the kind of money it takes to hobby? And I personally hobby for the GFE (emphasis on GF). If all I want is a nut, "Well, have you heard about this thing called the internet?"
My (probably too damn long) two cents...
