What exactly is it that makes people want to enter such a relationship? Is it just the sexual pleasure they get from that? Do many of them also love their partners? How does communication work in such a relationship? (I'm not talking about BDSM-related communication, but about all the types of communication that normally appear in a relationship) If the main reason for being in such a relationship is the sexual pleasure that both parties gain from it, how can it really be maintained 24/7? (assuming the two partners aren't hypersexual, they'd presumably get tired from continually maintaining the power differential, wouldn't they?) Why aren't these people content with a more "equal" relationship?
