Old thread, but maybe someone like me will read it late.  I believe in Nevada, counties control the brothels. If they do not want them, they do not have to allow them to operate. There was a good book by a reporter who lived in one of the legal houses and got the trust of the girls. I wish I could remember the name, but a librarian could find it, or even someone who uses the library enough to search. Maybe on Amazon.  I did not notice any lack of providers in Las Vegas where prostitution is illegal. I guess they just chat and watch TV with their clients.  My experience in South America showed that many of the bars and such, as well as providers are under the control of the police. If they feel like making trouble for someone they will, as will the providers themselves, for no good reason. Mix in all the drug money and poverty and the business becomes sordid, unfortunately. In London, I visited eight years after WWII and street walking was legal. The women were very well dressed, very polite and very good looking. They could and did make the first offer. A few years later this became illegal, driving the sex business underground where it became much more trouble for society since it was much harder for LE to know what was going on.  The providers, alas,   were a little too expensive for me and anyway I was still under the influence of a Catholic upbringing that said I would go straight to hell if I dared to have sex outside of marriage. Great advise to give a 19 year old who couldn't marry anyone if he had to. The right hand man got all the business. Later on GOD actually protected me for many years as I NEVER used a condom anywhere in the world and NEVER got any disease.  I am also glad that I more or less quit this behavior shortly before AIDS and other diseases surfaced in the current awful epedemic.
