I just read an excellent review about a young hottie's first-ever experience as a provider.
One thing that piqued my curiosity was the the OP's assessment that she "may be overly eager to see the money (she must've asked me three times)."
I can only infer that the financial transaction took place at the end of the session.
I understand the provider is totally new, and very uncertain of herself; but since I started playing, I've always left the donation, in an unsealed white envelope, on a dresser, TV, or some other conspicuous place, right after the greeting kiss/hug. Never considered doing it any other way.
(Well, "always" except for that one time I totally forgot, and embarrassed myself with a lady I've seen several times, and whom I adore!)
So, my question: What are the ladies' normal expectations -- to get the donation at the outset, or at the end, of a session? Does it matter, and why? Am I the exception?
