Jack Morin was a San Francisco sex therapist and author of The Erotic Mind. Through therapy and an anonymous Sexual Excitement Survey, he explored peak erotic experiences, fantasy, ambivalence, obstacles, and the personal themes that shape arousal. His work offers a non-moralising vocabulary for erotic imagination while requiring clear separation between fantasy, action, evidence, and consent.

Sandra Bem was a psychologist and feminist scholar who developed gender schema theory and the Bem Sex-Role Inventory. Her work examined how people learn to organise information and identity through gendered categories, and it challenged the assumption that healthy people must fit a strictly masculine or feminine pattern. Her legacy is useful when read critically, especially around measurement and identity.

Douglas Braun-Harvey is a sex therapist, educator, supervisor, and treatment-model developer who brings sexual health into mental-health and addiction services. His work reframes out-of-control sexual behaviour through consent, responsibility, health, relationship context, and practical change rather than relying only on the contested language of sex addiction.

Irmgard Bartenieff was a dancer, physical therapist, movement educator, and scholar who extended Rudolf Laban’s work through anatomically informed principles of connectivity and function. Her Bartenieff Fundamentals explore breath, support, developmental movement, weight shift, and whole-body organisation. Her work supports adaptation rather than a single ideal body.

John Bowlby was a British psychiatrist and psychoanalyst who developed attachment theory through dialogue with psychoanalysis, ethology, psychobiology, and systems thinking. His account of proximity, protection, exploration, separation, and loss shaped developmental psychology and relationship therapy. For sensuality, it offers a language for security and approach while requiring care about cultural context, developmental complexity, and the danger of turning attachment into destiny.
