CBT is a BDSM activity that either makes men cringe with fear or lights up their faces with delight. This book is a guide to this form of play with excellent info about the following topics: basic male anatomy, negotiation and safewords, play benefits and risks involved, safe sex play and cleaning CBT toys, and also descriptions of various CBT toys. While CBT is not specifically my idea of fun, the book is still very entertaining and informative.
