For the life of me, I don't understand why any of you lovely ladies are concerned about chicks who charge $50 a pop. That's not your market. They aren't taking your business. They aren't ruining the curve. It's comparing apples to oranges.
It's essentially like me being insecure in my own situation because someone is out there who is only charging $300/hr. it doesn't matter because the situations aren't comparable.
Guys are seeing YOU and paying YOUR rate because you're the girl who turns them on. They are picking you. Why worry about someone who you clearly don't consider to be in the same league?
Set your price. Make yourself worthy of it. Men will pay you whatever they perceive to be your true worth. It's up to YOU to set that standard high.
