Meh- yea dance instructors have more leeway, so do doctors, nurses, massage therapists- it never caused me any angst- I got used to my first pro touching my face, hips, rib cage etc. maybe because I do the same to people in my line of work, it's not an issue. Having said that, I can see why some may be uncomfortable- allowing another person access to your body could be intimidating and crossing a boundary, except, in some lines of work, it's obvious and shouldn't require a second thought..
