Calling the shots, being in charge, or otherwise directing the sexual experience. As a dom (dominant), there’s no one “right” way to do it: you can soft dom with lots of praise, you can tease dom with orgasm denial, etc. The thing all doms have in common is their attention to consent and the safety of their submissive: if the submissive’s job is to release, the dom’s job is to structure the sexual experience.
