Punishments in Discipline
The goal of discipline is to teach the submissive how they should behave as well as the consequences that may arise as a result of breaking the rules of behavior; by undergoing punishment if they break the rules, they learn self-restraint and become better subs. The punishment is generally related to the mistake, and is generally proportionate to the severity and frequency of the mistake. For example, a punishment for speaking out of turn for the first time may be a simple restraint (such as being silenced using a gag). Similarly, the punishment for a submissive getting an erection when that is against the rules can be a chastity cage.
The submissive may also be given the option of choosing his/her own punishment from among options. For example, for a minor mistake done repeatedly, the punishment could be an option to be either caned a few times (physical punishment) or be paraded nude in public with a pet animal leash where such is legal (mental punishment). Or a punishment for a severe rule breaking could involve a choice of whip or cane as well as for body part (such as back or buttocks), on which to receive 50 hard strokes.
