As far as some people are concerned, BDSM relationships with a dominant and submissive position are unequal. The dominant and submissive parties in a BDSM relationship may seem to be unequal, and the dominating partner appears to have complete authority. The dominant and submit in a good BDSM relationship should exchange power in an equitable and mutually agreed upon manner. It is essential that the submissive partner in a relationship freely and consensually submits to the more dominant partner. Any time they want to take back control of their circumstance or relationship, submissives have the option of doing so at any given moment. At no moment should the submissive feel belittled, uncomfortable, or dangerous. Ultimately, the power exchange in the partnership becomes equal as a result of their mutual submission to the dominant.
