real newbie.  I see some ads saying real gfe experience, others that say NO gfe.  What is the distinction?

What is a GFE is a highly debated topic.  Basically the GFE is holding, kissing, cuddling, some see the need for DFK, BBBJ, and greek to make it a GFE.  I would be careful if a add is saying extra $$$ for a GFE.  To me what a GFE is is all in they eye of the hobbiest.

The attitude a provider has also determines if she is a
GFE or not.If she treats you like a "business" transaction,
then your chances of having a GFE are pretty slim.
If she treats you like you are the only man on earth,and all
she wants to do is please you,then your chances are looking up.
Sometimes the length of her "do not" or "don't" list can be
a deciding factor.If all she will allow is CFS and nothing else
then look elsewhere for your GFE. If everything goes except
for maybe "greek,"(which is very common by the way)then get
ready for a possible GFE.I think it all boils down to YMMV.
One mans trash is another mans treasure. A GFE to you,could be a (6)or(7) on the performance scale to somebody else.
