Dominance refers to the act of dominating the other person in sex and outside it
Sometimes, those who are dominating will have different types of arrangement with their sexual partner on how the partner should behave in bed, and even out of it. This can be anything, from clothing style to food habits.
Submission
Where there's dominance, there's submission as well. The submissive partner will follow their dominant's actions by ensuring that regulations from their arrangement are not broken. The dominant (dom) and the submissive (sub) are focused on communication.
