*tapping the microphone* Is this thing on? *cringing at the feedback*
Well, Mr. Radio-talk-show-host, why ask that question about just D/s? What does a "normal" couple get out of their relationship? How does their "regular" relationship better their lives?

Just the existence of a not-quite-mainstream power dynamic doesn't make us any different that any other relationship.

i suspect there are as many answers to this as there are couples in the world.

For me, though, the D/s dynamic simply calms a part of my soul that is not quiet without it. i don't know why, and i don't really care why. i just know it works.
