I believe the sub/dom relationship has a lot of other aspects that those that are physical, and the intellectual ones are just as important. Personally, having a dom who expected me to become a mindless zombie would be awful. I believe that subs/doms shape each other, like in all relationships, and so inevitably take on qualities or beliefs that they share with each other. However, I don't believe this is a one way exchange. Experiences shape people, and therefore I doubt a dom could remain stationary or a sub should be forced to lie. Submission of motivation is submission on a level that destroys personality and therefore humanity. I believe that BDSM is as beautiful a way of displaying love as sexual acts or even poetry - therefore I can not see it being a good thing to taint said acts in any way, least of all by ruining the people who partake.
