Banana although you asked the question of another may I attempt to answer... "I think most prostitutes probably are damaged or desperate.... but i don't know how you can be so certain that all fall into this category? If so how do you explain this story..."
I guess for me I would take the starting point of the present day and say that a woman who willingly put herself in a room with a total stranger and committed to not just sex but presumably many bizarre, embarrassing or reckless/unsavory acts he may require is not someone who is necessary a happy and well balanced person. Most of us have a sense of self preservation that would over ride this kind of activity.
The thing you link to doesn't necessarily cry totally true to life and real, and even if all the people are real, do we really know they are who they say they are.
Just look at the answers...
"My parents don’t know about my work, or anything else about my sex life."
and
"...but I still had not really explored many of my desires. I was meeting people living alternative lifestyles, and, as I got to know them, the stereotypes that I had built up started to come apart. During this time I was in my mid-twenties, and I had an active sex life."
This implies that the women sees her 'work' of being the sexual reciptical of any paying man as some part of her sex life. I really wonder if prostitutes really see their work as part of their normal fun enjoyable life?
Q.
Have you ever ‘fallen in love’ with a customer?
A.
Yes.
I do find this rather hard to believe. This sounds very Pretty Woman.
David I don't keep digging until I understand why a woman becomes a prostitute. There may be many reasons. I've heard of women who introduce their kids into this so-called profession. But I do wonder how any man can want to have sex with a woman knowing she is only doing it because he is paying. Maybe we need to explore what makes men tick that in any universe that is acceptable.
