If you're looking for a how-to book of tying up your partner, techniques for using tools, what parts of the body are safe to strike, etc., you'll have to look elsewhere in other books that cover these subjects. If, on the other hand, you want to know why on Earth would anybody want to do this in the first place, you've hit the jackpot in "Radical Ecstasy."
If you think BDSM is all about cruelty, Dossie and Janet will convince you otherwise. They are incredibly articulate about psychological processes that are nearly impossible to describe. Come along with players on their journeys to the darkest, scariest parts of their minds and watch them emerge cleansed, whole, free, and (most importantly of all) LOVED by their play partners. Their role-plays may well be more effective than hypnosis or years of therapy on a shrink's couch. The authors feel their words do not do the experiences justice, but truly they are too modest.
I had the good fortune to meet Dossie and Janet at a Polyamory convention, having already read their classic "The Ethical Slut" which is far-and-away the best and most practical book about the dynamics of Polyamory. They are cool ladies who would be mistaken for ordinary vanilla if you didn't know otherwise. "Radical Ecstasy" is every bit as revelatory as "The Ethical Slut," opening up a whole new world for me.
At one point in reading it, I collapsed in cathartic laughter that made tears stream down my face, when I suddenly realized that I had always been fascinated with bondage games, even as early as age 8. My obsession with "Perils of Pauline" scenes became a source of enormous ridicule from my schoolmates, so embarrasing I never dared breathe a word of it to anyone for more than 30 years. At long last, Dossie and Janet proved that there was nothing wrong with me after all! I was merely trying to act out a logical resolution to the school-bully problem. My first-ever night at a BDSM club saw me tied to a St. Andrew's Cross while wearing the most demure, innocent, Victorian-vintage lace dress imaginable. Eventually, I might finally get to act out a resistance/takedown/rescue scene where I get chased all over the dungeon . . .
THANK YOU, Dossie and Janet, for sharing your amazing love with the world.
