I think you are confusing sex and power exchange. As enjoyable as the sexual aspects of a relationship are.. the two are not always synonymous with each other. Sure, some people choose to only engage in power exchange in the bedroom (and there's nothing wrong with that, we are all different and have different needs).. but many, the Old Guard included, make that power exchange a way of life (or a lifestyle). Such people are not having sex 24/7.. however, their power exchange does apply 24/7. It's who they are, rather than something they do.
