I'll tell you this much:
It takes confidence to be submissive to your spouse. Being submissive is an act of trust. Being submissive to each other is its own benefit, in that one of you doesn't have to be 'strong' all the time - something I have found to be practically impossible.
Being submissive to each other, to me, is the ultimate sign of strength in a marriage.
On top of all that, its hot.
Smart MAY be sexy. A casual confidence is DEFINITELY sexy.
