No one likes to think about an SM scene going wrong, but the truth of the matter is that it happens. An important part of responsible SM play is being prepared for emergencies, and I know of no individual more qualified to provide education about such things than Jay Wiseman. Jay has been an SM practitioner for many years and is a veteran EMT. The advice in this book is practical and written in a clear and concise manner. I have given away copies of this book (and other books of Jay's), and will continue to do so. Other books he has authored show how to please a partner sexually, or to do lovely and hot erotic bondage, or to build your own toys, but this book--this book can save a life.
