you might want to read an essay by laura antoniou entitled, "unsafe at any speed or safe, sane and consensual, my fanny". i know that it is in her newest collection, "the catalyst", but don't know if you can find it elsewhere.

her rant in essence is that bdsm has been watered down by the ssc credo. she believes that part of the thrill of bdsm is the fear and the danger and knowing that you have set all kinds of limits takes all of that away.
