Not having read all of the thread, but enough for me to realise there is a massive amount of outrage & misconception of the sex industry on this thread.
Several of you are obviously coming from the over thought, not real clue feminist angle & speaking as someone who DOES have pretty close experience of this industry - not me personally, but through my work I have known many girls & several guys well enough not to prejudge, go off in my own little, I'm a self righteous, all knowing, always right feminist fart
& but to actually ASK those involved how it really is & from that I can say for a large part, especially with the properly organised "Brothels" & high end Prostitutes, I have never met one who is there because they felt out of control or forced by those evil things we call Men
These women were VERY empowered & could no doubt give several of you a run for your money in REAL life - they do it because they love sex & as such its a bloody good living -
Also one of my oldest & dearest friends used regularly nip off to Amsterdam to work she again was a bit of a nympho, often dishing out in her word "the charity shag" to guys we knew who didn't have a lot of luck with women - trust me she is no wilting, controlled abused poor little woman, she just knows what she wants, loves sex & therefore it was for her the natural choice of work - she could earn enough in a few weeks to set her up for months too - NONE of these women were doing it for any other reason, than because THEY chose to.
I also have another friend who back in the day was a very beautiful high class hooker, she used to earn thousands for one weekend & was regularly flown around the world at clients expense, yet often her role was not full on sex, something she found quite odd & was disappointed with - she always had some great stories to tell though 
also the industry is VERY strictly regulated - & as such the gils are regularly tested for STDs - so probably actually LESS of a risk than picking up some stranger in a bar
Of course there are the streetwalker junkies & the poor 3rd world women who find themselves working unwillingly in substandard brothels under nasty violent & controlling pimps, but that is a whole different ball game & as such you just cannot judge a whole industry on what you see on TV or in the papers & a section of it - MANY women are in it because it suits them & they want to be there?.
I personally don't see any problem with single guys using these services, if they can afford it & thats what they choose to do - married either IF their wives/partners KNOW what they are doing & happily approve
What is wrong here is the deception & subterfuge involved in partaking, thats not something that paints a picture of a "Good man" & having been in a relationship in the past with a guy that did exactly this, yet on the surface was an all round good guy - yet was actually a very sad individual where nothing I knew him to be was actually the truth.
