a few thoughts
Why is it different if a a person who works in the sex industry be any different to a hair dresser, beutician,doctor phyiso ect. They all work with peoples bodies and provide some sort of service.Perhaps a doctor's wife will not trust the doctor if he gets close to his patient and has to check his client in a fairly intimate way Virginal swabs , boob checks ect.
So if you are sex worker and a client comes in, surley he is requiring a service. He would be paying for a block of time. Once he leaves surley he goes back to his wife and continues to be happy few marriages are perfect .I am sure that the service provided is mainly physical. Much better than going out to pubs and clubs and having a full blown affair.I would imagine a sex worker would have a better understaning of the male mind in more ways the one. I think when the sex worker does find a true love she will most certainly know how to keep him happy and if he is to stray to say to another working lady i am sure she would have the right accumen to understand why.
I have also heard that there is nobody more loyal than a working lady that has retired............
