There is nothing wrong with ethical sex work (people who CHOOSE to do this, set their prices and receive the entirety of the money and choose their own clients).
It is very different now, than it used to be and a lot of people are making the choice to do this work because they love sex and they see it as providing a service for those who need it.
I know several people in the industry who love it and wouldn't stop because it's fulfilling for them.
The judgement on mumsnet is ridiculous and some people here make it sound as though all sex workers are drug-addicted, underaged, trafficked women which simply isn't the case.
The good thing about this new wave of ethical sex work, is the more people who use their service, hopefully the other seedy side of things will get less and less.
The problem with male sex workers is a lot of them are just horny dudes who want to get paid. They don't understand or have any intention of treating it as a professional service for the female client, do you need to be very careful who you choose.
I think that its a wonderful idea, a bit of self exploration, sex with someone handsome and maybe learning what YOU like now :)
