Sex is a trade, it's the oldest job in the book, in history, it's also a tool that women have used for centuries to get what they want eversince 'chivalry' came into being. It's legally two adults who do whatever they want to do behind closed doors. Not everyone is a loser on either side of the trade. A self-hating SP who drinks on the job or takes quite large amounts of drugs is a "loser". A client who has no standards, isn't it really hobbying either, but has everything from a mental, psychological and physical perspective to be perceived as a loser, is a loser because the label just fits.
Some SPs actually make it. An example is the ex-SP who is now the proud owner of the Strom Spa on Nuns Island (that is the rumour I heard from an SP). Or Nathalie McLennan (although, it is possible that she is actually the owner of the Strom, I don't know). Ofcourse, after an SP is done with the business, she dissapears, we don't know what's she done with her life.
In the end it all comes down to intelligence. If you do the job like she does, but you put some money on the side, and then start your own business eventually with those savings. Than that kind of woman is hardly a loser.
As for men, usually, we're losers for other reasons, not because we can't get laid (although that's not the case for me, I can get laid perfectly fine)
