Outside of the poor grammar, terrible spelling and unorganized sentence structuring this book feels completely out of order, which lead me yelling at the book out of fear for inexperienced BDSM members reading this book as their first guide and impression. Discussing safety and limits should always be an introduction on the subject, not forethought for later chapters nor jammed into the middle of chapters.
This book assumes its audience and those practicing are hetero-BDSM curious individuals looking for sexual adventure as such it lacks diversity for alternative practices of BDSM outside of the D/S lifestyles and non-sexual BDSM activities or how BDSM and its dynamic itself can be a completely non-sexual experience.
In conclusion, this self-published book is a work of love for the author, but as a proclaimed "expert" on the matter, he's only presented an unorganized overview on the subject. While I'm for self-published authors and supporting them, I would recommend getting this book through his website instead of buying it.
