It is a job though. Newsflash - people do jobs for money. Prostitutes are paid to sexually pleasure men within whatever boundaries/services advertised that she is willing to provide. Some
clients are sexy, genuine chemistry and amiable, even charming guys (bonus
clients are arrogant, lacking in personality and not personally attractive to the lady. So long as the customer is clean (or gets clean on arrival) and not pushing boundaries of the lady, with a good prostitute you will not be able to tell if she dislikes you. If the chemistry is not there or she thinks you are ever-so-slightly an asshole she will put on a good performance so you probably won't tell or have any reason to complain.
It's a job, essentially a customer service job with added elements of perhaps "touchy areas" with other mainstream customer service jobs don't have.
Obviously it is mainly about the $$$$ and what the money can be used for (ie funding education, buying property, maintaining expensive lifestyle, flexible hours etc etc etc). If a woman just enjoyed fucking random strangers semi-indiscriminately (I say semi because obviously there are cases like poor hygiene or boundary-pushing where the lady will refuse to continue or start the booking) then she would simply go to a swingers club or put up a personal ad.
You are paying for a service/ transaction in which a woman (or sometimes a trans or gay man) offers a set selection of services for a set amount of time in exchange for a set amount of money given to your chosen lady for providing you with such services (ie - for having sex with you). No emotions, love or even attraction (well for the pro$$ie!) are required in the transaction. It's essentially simple, clean-cut , empty sex.
It's as simple as that. Therefore I have no problem with the "Pro$$ie" nickname. But I do have a problem with service providers just doing their jobs being described as "greedy". It is lucrative to be a pro$$ie because of the fact very few women are inclined to take up the profession and also because men have high sex drives (as do women but not in the same way) and a lot have appetites for variety (which not many women have) and sometimes prefer much younger ladies than they could ever hope to have sex with in everyday life (so remuneration is required). It takes an intimate physical and sometimes mental toll on the ladies and restricts real-life relationships and prostitution is a job with a 'shelf-life' so to speak so therefore is well-paid. That's not greedy. No-one else is called greedy just for doing their jobs.
Methinks some people perhaps resent paying the money just as much as they sometimes claim prostitutes resent giving the service.
