A therapist who is Kink Aware recognizes that BDSM, Polyamory, Swinging and other alternative sexual and lifestyle practices are part of the normal sexual spectrum and is able to distinguish healthy sexual play from non-consensual abuse. Kink Aware Therapists (KAT) have additional postgraduate training about alternative sexual expression via, books, articles, continuing education, seminars, websites, etc. KATs are aware what constitutes safe and unsafe play (acknowledging of course that different people have different standards for that). KATs are aware of the roles and role expectations of those who participate in alternative sexual expression lifestyles. Patsy Evans has been an active advocate and Kink Aware Professional for the alternative lifestyle communities for more than a decade. She is also a public speaker and activist for the sex positive culture and freedom movement.
