A traditionally marginalized subset of couples engage in consensual nonmonogamy (CNM: open marriage, polyamory, swinging, etc.) or alternative sexualities, such as kink or bondage/discipline, dominance/submission, and sadism/masochism. Nonmonogamous and sexually diverse individuals often experience discrimination or stigma in various domains of professional services, including mental healthcare. These cases require knowledge, skills, and awareness to provide culturally sensitive care, which is often called “kink aware therapy” or “poly‐friendly therapy” within alternative sexuality communities. This article explores one application of a kink‐focused and CNM‐focused therapeutic framework for working with a couple who is exploring nontraditional sexualities. This case incorporates evidence‐based clinical practice and identifies the limitations and significant gaps in the empirical research literature.
