Thank You, SirW.
My signature is 'Everything has a price.' A true BDSM relationship carries an emotional price as well; caring, trust, and responsibility, on both sides. If that price isn't paid by both sides, the relationship, while sexually/physically satisfying, isn't emotionally satisfying. And emotional satisfaction is what we, as human beings, are drawn to each other for. When two dogs mate, there's no emotional satisfaction; it's all physical gratification. We humans have been gifted by The One with emotions, and the intellect to use them, so why waste that gift in a relationship where emotional fulfilment isn't a part?
