It goes by many names: bondage & discipline, dominance & submission, sadomasochism, and more. Now, the long-taboo subject of consensual SM is coming "out of the closet." Since the early '90s, this underground classic book has taught the fundamentals of safe, exciting SM to tens of thousands of people of all genders and orientations. This expanded second edition includes many revisions and updates, including a brand-new chapter on starting and running SM organizations and events.
