I think the web sites are shit and its very hard to fine anyone who is not nuts. Plus you just do not know what you are getting into.
But as a concept of this having a hooker on tap where by you enter into some form of arrangement will work for some people
However in London I suspect the entry level is around £1500 a month and some soapy city boys pay 5k amonth.
For that you get to see a mid twenties Fit as fuck EE/other once a week, however she could will have another 2 or 3 guys paying the same.
You will get the I love you bade texts on the Days you don,t see her if you are into that,
So a smart girl can bag 5k a week having three blokes in her life that she is comfortable with and would not have to worry about much.
From the the punters point of view you get to fuck the same girl every week and its cost you £1,500 a month that may work for some.
I have been there done it got the Tee shirt as they say. Its bollocks for the Most part and ends up doing your head in.
But I am sure its possible for some to find a comprise that works for both parties. People can do as they wish with there money its not for me to judge anyone.
