While it is more common these days for Dominant/submissive couples to have Top/bottom kinky play, the 1950's head-of-household style D/s relationship is an example of D/s without the T/b. In addition to no kink, some D/s relationships are not sexual either. Top and bottom are different than Dominant and Submissive. Therefore we can stop relating them to one another because ultimately we are making it even more difficult to learn their meanings by doing so.
