Kink: Otherwise known as BDSM (bondage and discipline/domination and submission/sadism and masochism), fetish, and/or S&M, “kink” refers to a lifestyle or practice based on consent and mutually defined activities that, according to TASHRA, involves “eroticization of power via dominance and submission, role playing/fantasy, and/or intense sensory stimulation and/or physical restriction.” Polyamory or poly: Maintaining multiple sexual and/or romantic relationships simultaneously all people involved have full knowledge of the situation and are completely consenting. While the concept of an “open” relationship may seem self-explanatory, there are many different forms of non-monogamy that can include a variety of sexual practices and philosophies.
