At least for me, the Dom/Sub, Master/Slave kink culture is about: - The earning of trust - The allocation of control - The fulfillment and gratification of all parties involved. In that order. Your dom/sub relationship doesn't even have to be sexual in nature.

Sometimes, it's just nice to have someone else in control and making all the decisions, and for some, it's nice and enjoyable to be the one trusted with being in control and making all of the decisions. Even with day to day stuff.
