This is like asking which kind of execution you would rather have, because either answer would involve something that would feel like an amputation.

Being submissive does not necessarily involve a total surrender of control. Far from it. Submissives often like to be in control, and liking submission, they can also enjoy and understand the submission of a partner, who also provides the dominant element when the switch is the submissive. Being in control, even while in the submissive role, is a part of the personality that you can't give up, if you are that way inclined, any more than you would want to give up experiencing the physical sensations of the submissive role.

So is the person I am describing a switch? Or just a masochistic dominant? We might expect the opposite of a masochistic dominant to be a sadistic submissive, but that sounds like an improbable combination. As combining two negatives makes a positive, perhaps the opposite of a switch is really either a sadistic dominant or a masochistic submissive.

So what erotic_nibbles seems to me to be asking is whether a masochistic dominant would rather stop being masochistic, or stop being dominant, but interpreting the question that way doesn't make it any easier to answer.

The nature of a masochistic inclination is very different from the nature of a dominant personality. Masochism involves your own physical sensations, while dominance is how you interact psychologically with other people.

Self-bondage is indicative of masochism. A dominant will always want to remain in control, while a submissive will be tempted to surrender control. My advice would be, if you are naturally submissive, don't do self-bondage!
