What is he watching?

George Rodosthenous' introduction to this collection on essays on 'staring at the forbidden' offers a list of 14 voyeurisms that might be in play during a theatrical performance. While some of them are marginal - seriously, 'pathological voyeurism' (having a wank while watching a show) is not something that I have encountered more than once - the range covers both sexual scopophiliae and more high-brow intentions. 

This list was developed from Clay Calvert's Voyeur Nation (2004). I was hoping it might open up ideas about why I go to the theatre.
