I think a full-on BDSM relationship is very rarely, if ever, a good thing. If they uphold mutual respect and equality at all, they do so in a very strange, inverted sort of way, and it's far, far to easy for the dominant person to get out of hand and become abusive.
I think BDSM ought to stay in the bedroom or othewise be kept as a sort of sex game. But what your contemplating is making much more than that, ie, turning your entire relationship into an extension of your sex life. By doing this you risk not giving enough emphasis or consideration to the other non-sexual things that make the relationship work, and if you do that, ie, putting all your eggs in one basket, how can you keep it going? In my view, it's a strange, new fashion that had better not last because it isn't a basis for a stable relationship in 99 cases out of 100, and perhaps the other case is Secretary a work of fiction.
What motivates you to want to be submissive? Why does he want to be dominant? Both of you need to look into the reasons why, because they could be thoroughly bad instincts that will betray you. Are you doing this because of some trauma in the past? If so, is this the best way to handle it?
