None of the things you're critiquing are intrinsic to sex work and your argument is that it is intrinsically degrading. You made the point that work isn't intrinsically degrading, since you don't consider working in prestigious fields like medicine or law to be, nor do you consider working in physically demanding and less traditionally prestigious fields like garbage collection. I pointed out that sex isn't degrading either, since it isn't, sex is just something people do with each other.

So, since the only things intrinsic to sex work are that you're performing sex as a form of labour it raises the question; Where does the intrinsic degradation lie? In the labour or the sex?
