I used to go out with a woman who worked as a professional dominatrix and though its not prostitution as such (being as there is no actual sex involved) its often lumped into the same category and some of the offences (such as living off immoral earnings) can also be applied in the case of arrest.
She had no qualms about doing the job, she saw it as basically a form of acting and it paid very well. She had never ben troubled by the police, worked from a nice house in Chelsea, paid taxes (though she was officially a ‘relationship counsellor’) and had quite a large amount of wealthy clients (bot male and female) and some of them were fairly well known public figures.
