Wow. Alright, please inform my ex-fiance that he is an evil person who treated me like a hooker because he was never able to get me off. Loving, commited relationship, and not one orgasm. But that's not why I left him, but it certainly added to the list. Sex doesn't equal love, love doesn't equal sex. Well, not good sex anyway.
As to the second point, if a man wants to go to a hooker, with them both understanding that she is not vested in a personal orgasm, the point is his pleasure. She provides the human element to the sexual encounter, he provides the incentive. In this case the incentive is cash. In many modern sexual encounters there is still an incentive, it's simply a different one. Perhaps it's the hope of a relationship, of marriage, of long lasting love. In others it's pure shared physical enjoyment. There is always a give and take, always a price to be paid, in sex.
Perhaps the cost is falling in love... perhaps it's being left... perhaps it's wanting the sex again but not having the opportunity. But in a consenting, adult, paiding-for-sex relationship the cost is obvious. We can argue about what price she pays for her cash, but the point in all of this is that it is still her choice to pay that price. As it was mine in having sex with a man when I knew the price to be paid was my heart. I fell and it was a one way street... My heart, my price. Is non-marital sex evil? I sure paid a price, I felt dirty, I felt used... Because I made bad choices about who I slept with. Again, my body, my choice, my price. It's no one elses business, and that includes if the transaction had included money. That it didn't simple proves that any sexual encounter can be positive or negative.
Besides which it all lead me to understanding what fidelity means, what good sex really is, and what I wanted from a partner. You generalize about love and sex, you wan poetic about love and sex, you glamorize love and sex...
But you still have no proof that one ounce of any argument that you have attempted to make proves in anyway that any of the evils you see in prostitution are anything less then part of the human condition. As many others have said, if you want to talk about slavery, child sex trade, human trafficking, then lets talk about that. Sex between adults is convoluted in the best of circumstances, and attempting to moralize another to your standards is insane.
