Is burlesque sex work?

So I went to TESfest (don't laugh.) I took several classes, all very interesting, of course. One class I took was "Dirty Sexy Money" taught by one Miss Calico. Basically it was a class about sex work, sort of the ends and out of the trade. It kind of turned into philosophical discussion about what sex work is. So I asked her if she thought burlesque is sex work. She basically said that sex work is "doing sexy things for money", so therefore, yes, burlesque would be sex work. Under that broad of definition, almost anything could be sex work. Burlesque is usually sexy, and I suppose we do make money, not a lot, but some. So I can understand that. But I wonder if that might really make some people really nervous to think about, because it seems that some performers are still nervous about burlesque's association with stripping. And to think that burlesque could be associated with protestution or other occupations that are normally associated with sex work, would really make them gag.
