Books I like regarding my kink and relationship. In no particular order.
Speak Ericksonian by Richard Nongard.
Neuro-linguistic programming, and conversational/covert hypnosis. Athena and Her Subject conversationally hypnotize each other without going through formal hypnotic inductions.
What Shamu Taught Me About Life, Love, and Marriage: Lessons for People from Animals and Their Trainers by Amy Sutherland.
Mostly on how Sutherland trained her husband. However, the knowledge can be used by dom or sub to train their partners to be more dominate/submissive. For subs can’t get enough kink, a great companion to Getting her to be a Vanilla Dominatrix. Psychology and behavior modification.
