Helpful Score: 3
Contains lots of useful information about the technical details of S/M. My only complaint is that it gets a bit "one true way"-ish in places, dictating that submissives (in particular) "should" behave a certain way, when surely the flavor of a scene or the details of how it's played out ought to be up the individual players to decide (once safety concerns are taken care of).
No pictures, in case you were wondering.
