Paradoxically, what we all have in common is that we are each unique! Therefore, we deserve to be treated as unique.

Too often 'cookie cutter' protocols are used to treat submissive/slaves. This is OK in the training and consideration phase but once a slave the Master should know enough about his/her slave to know what is the slave needs and what limits need to be pushed. Yet, the slave doesn't know either; so there is exploration and pushing of limits is the rule. This is where safe words play a role--at least in the early stages.

Open communication and honest feedback is keep to maintaining any relationship...including a D/s and M/s ones. You are a doormat if that is what you want/need. Ironically, a Master not treating like a doormat when it is what you want/need is abuse.

So, the answer to your post is complicated by the uniqueness of the Master/Dom and the slave/sub. Perfect matching is impossible but the continuous effort is to match control with needs.
