Can';t imagine this one even being a point of debate or discussion - sex workers are just people like anyone else. They're in an unusual line of work, but not one that is more or less immoral than, say, a business man.
This kind of place is most definitely not representative, and is probably one of the worst places to derive a sense of this kind of thing. It's not for nothing that the guys who are here are here.
etc...
tbh, I find most SP's aren't any more beautiful than what you might see on a regular day in the metro or wherever. While looks are important to me, it's very much about the energy.
