Since the thread was about what a collar signified for a submissive, I didn't include my thoughts on it from the Dominants perspective, though I did elude to them I think.
So since it was brought up, I will clarify. I did say that a collar signifies that the sub is in a committed relationship, one that I would desire. Just so there isn't a misunderstanding, yes, I would be also committed to that relationship as the sub and I defined it.
