My line of thinking is a lot closer to Oz's. I wanted to offer the voice of dissent earlier, but couldn't get my thoughts clear enough, so I just let it go.
In my version of D/s, the submissive is not in control, and submission is not a "gift". If it were, then the sub would really be the top, and that just doesn't work for me.
As always, your mileage may vary.
