What If my submissive breaks the rules often?

Often if a Submissive continually breaks the rules of the power exchange agreement then that is a red flag that something is wrong or not being communicated fully 

1 They may be burnt out, and need a break, 

they may need less tasks, or different tasks all together, Checking in ever so often with each other to make sure all is well is always a good idea. Some may be too stubborn to admit that something may be to difficult or more than they can handle, leading to burnout or depression

When discussing such matters, always approach with patience, and support. 

2 They may be seeking attention, Masochists can be known to push buttons to get the punishment reaction because it's about the rush and the thrill of the punishment they seek as well as the control. This is a form of manipulation known as Topping from the bottom. If the behavior is unwanted and discussed yet continues on. Then it's time to assess whether you deem the relationship healthy or not. 

This is true for bottoms or tops, Doms or Submissives. If you have communicated that a behavior or action is unwanted and if said behavior or action continues on. It is up to you and YOU alone to decide whether you want to continue or move on. That is apart of practicing Safe Sane and Consensual BDSM
