IMHO I absolutely think submission is a gift, just as I think domination is a gift.

I've heard it said that submission is not a gift that we give to our Masters, like some people try to tell us, because a gift can be taken back when it is no longer wanted.

Well, that very statement supports my argument that submission is a gift. Submission can be taken away. A submissive is capable of breaking things off with his or her dominant and/or taking away the gift of submission.
