It is each individual lady's decision on what her rates should be. Who is anyone else to tell her what she should charge. I personally don't know your rates but let's assume some girl comes in here and says that a hundred for an hour is too high should we all listen including yourself. No. Absolutely not.
It actually comes across as petty for you to start such a thread. Charge what you want. If a girl is charging 200$.... 300... 500.... hell 1000$ for an hour and getting it. More power to her.
