This is a book about relationships. Adventuresome relationships. Relationships that are not exactly like vanilla relationships. BDSM relationships differ in two specific ways from your typical vanilla relationship: first, they usually involve a power-imbalanced structure (one person is clearly in charge and the other person is clearly following); second, the kind of sex that adventuresome folks practice is, well, not vanilla.
I wrote this book to help you better to understand the power dynamics that get involved with what are called power-imbalanced relationships (usually referred to as Dominant/submissive or D/s relationships).
This is the second book in this author's BDSM Mastery series, but I started on this one because I have the basics down. However, after how much I loved this book, I'll probably go back and read the first, because I just loved this author's writing style. So often reading alt-nonfiction books I am slogging through poor prose and copious typos, diatribes of pedanticism, and downright problematic ideas without qualifiers. Not this one. This is the M/s book I've been looking for. I wish I would've read it before I had to learn so many of these ethical lessons the hard way; Rubel's ethical advice is pointed and practical. I'm not just talking relationships...this book says a lot about BDSM communities that you usually only learn if you're heavily in the scene for years. I especially love the breakdown of roles that other books only skim the surface of; this book deep dives into the language of labels, including the adjectives that get thrown around such as "sensual"...words that sound basic enough, but you realize aren't discussed as much as they should be. If you're an introspective person who prefers precise discourse and strives for expertise in subjects that interest you, read this book.
