I have talked with t about my "interests" that are along the same lines as yours. There wasn't really much to talk about, though; once I told her "this is one thing about myself that I am SURE of; it is part of who I am, I am just wired this way." I told her, to give her context for a dream I had had. JS is right, the sub is not surrendering their power. At least, not in a healthy D/s relationship.
And she basically responded well if you don't have a problem with it, then there's nothing for us to talk about. If it ain't broke, don't fix it. Every now and then it comes up randomly and she doesn't seem to have a problem with it.
