Ive actually seen dominants that thought love was a weakness and even submitted to such on occassion.
Though I have since been shown by my Owner that love is hardly a weakness, in fact it can be one's greatest strength.
What I was saying is that I believe both the dominant and submisive can make sacrifices to and for each other in different ways at times and catagorically universal sacrifices at other times to and for each other depending upon their relationship dynamic.
I was't posing a question of power exchange at all, merely nor sugesting that a dominant is submitting by careing for their property's welfare so much as owning up to the inheirent responsibilities of wise dominion.
