interesting thought, as any dominant takes on the responsibility of a submissive, not only are you a friend, a lover, or anything else that the dominant wants you to be, but you also take on the aspects of an artist's rendition in it's developemental beginnings, there fore the don is probably bring you to your potential masterpiece by having you learn to be that which he has not been able to obtain, every sub is a work of perfection for the gift they give to a dominant, and the dominant refines that even further in the rules they lay down for the submissive. every dom is an artist as we mold our submissives to our version of perfection. so of course our works of art are a higher standard than what we can hope to obtain. again i hope that makes some sense.
but yes, every submissive should explain how they feel to thier dom. i agree with Mr. tomcat in this. otherwise how is the dominant going to know if there is something that is out of 'whack' before more 'whacks' result
