Just my own opinion here but feel free to chime in with any of yours. When a providers posts a donation expense, shouldn't that be the LAST say on the price of time? That is unless she says she is posting a "special" or "ask about specials". There are a number of post with guys haggling like a shrew Arab trader over price that drive a provider to rip her hair out I would imagine. I guess in my opinion this just doesn't need to happen.
The term "cheapie creepy" I see recently, I am guessing that crows comes to ind as the worst offenders? I generally only partake in BNG/oral/BIG boobs and have done many single and double of these. These generally tend the be the "lowest cost". I don't partake in these because of the price, I partake because that is my thing and what I never EVER receive at home :-(. I don't do FS for my own reasons that I have had many condoms break in my outside hobby dating world. I look at it as a business transaction with a person whom I can also talk to, laugh a bit with, have fun, and above all RESPECT.
The providers on here do this for an endless variety of reasons, choice, lust, nympho, fun etc, but regardless of why they do it they should NEVER be made to feel inferior or an item to be tossed aside and ridiculed for doing what you are there for. Just remember you contacted THEM or raised an SOS in the ISO thread.
