This author's approach to SM is spectacular in it's cluelessness, hamhandedness, rigidity and misogny. How in the world can you write an entire book on SM and not mention a safe word even once? My advice for femsubs is very simple. The more a potential maledom partner tells you that he admires this book, the faster you should run away from him.There are a whole bunch of knowledgeable, ethical, clueful writers on SM out there including Pat Califa, Dossie Easton, John Warren, Catherine Lizst, Guy Baldwin, Joseph Bean, Lady Green, Philip Miller and Molly Devon, Jay Wiseman, Christina Abernathy and Race Bannon. While I have my favorites among them all are much better than the self-proclaimed "Sir" John.
