The B and M aspects of BDSM are as widely varied as the participants themselves. However there is one element common across the entire spectrum, and that is the Dominant/submissive relationship. Wikipedia describes it as “complementary, but unequal roles”. I think this is a perfectly elegant description of BDSM play, but the underlying foundation of the D/s relationship is actually very equal. In fact I would argue that it is more balanced than most traditional relationships.
