Just to be blunt here, if its a basic menu with all covered services then you should expect a basic price of 300. Atleast for me id never go more than that, but it seems other people will so what i would do hardly matters.
If its fetishes and Atleast bbj then id be open to dropping more, but it would have to cater very specifically to my fetishes and wants. Lets be honest with ourselves here, the provider is selling something, the client is buying something. In any other situation, if the client doesn't get what he wants then he simply doesn't buy and goes elsewhere, which causes competition for the provider to cater to that persons wants and needs better. But in this world if the client doesn't get what he wants then he just pays a premium for it anyways and just deals with the fact he is getting ripped off and will happily be open to getting ripped off even harder in the future. Its kinda crazy.
Women can be strict with their body, they have every right in the world to do so. But I can also be strict with my money. I found a good asian GFE regular that does pretty much everything and anything i want for 2 hours for just 300. She is great. If i can find a regular like that then im sure anyone can, but it seems mongers with throwaway money really just dont care and will pay 500+ an hour for just a hj.
