UK punting is an incredibly self-satisfied and unrepresentative site. Working girls can have their reputation amongst their clientele trashed by dissatisfied men with no comeback at all.
The wider debate on prostitution should not be drawn into consideration of this particular site.
Yes, many working girls are doing it because they see no other choice or at the very least they see no other choice that pays anything like the same amount.
In the provinces middle managers earn perhaps £35k per annum. At £150 per hour a working girl can earn that in 6 weeks at (37.5 hours per week) and it's tax free.
I abhor the practice of people traffickng and the enforced prostitution that goes with it so a fully licensed and legal sex industry would make the girls safer, would allow police to concentrate resources on those being trafficked and would remove the stigma from both sex workers and clients. It is not known as the oldest profession for no reason. Since it cannot be wiped out however much "right thinking" people believe it should be, let us at least bring it in from the cold.
Finally I cannot be the only man whose post-menopausal wife has lost both the ability and any interest in sex. My choices were to similarly abstain, or to coerce my wife, both of which I regard as unacceptable or to consort with independent British "escorts" or acquire a mistress. I prefer the escort solution as it has the lower impact on my domestic life. I don't use my real name with working girls and the cost is far lower than maintaining a mistress and the money comes out of my own private pension income and is easily affordable. So there are people out there who have had long monogamous marriages, highly successful careers and who are pillars of the community but still see prostitutes.
My argument against the accusation of infidelity is that one has to have something to which to be faithful. You cannot betray what you don't have.
