D

Dominance is one half of the DS (dominance and submission) in BDSM and is all about a consensual power exchange. With this particular kink, the dominant partner derives sexual pleasure from taking control. The submissive partner allows their dominant partner to, well, dominate them à la 50 Shades of Grey. Important note: Though the books and movies did help make BDSM kinks more mainstream, they're not totally accurate. Despite what the movie would have you believe, there's no research that suggests dominants enjoy D/S activities, such as spanking their partner, due to childhood trauma. And nope, you do not have to sign any sort of contract—all you need is enthusiastic consent from all parties involved.
