People assume that authority means the absence of rules. It is the opposite. Nothing happens here without being agreed first, between adults, in plain language.
Limits come first
You will state your limits before anything begins. I will not guess them, and I will not argue with them. Someone who hides their limits to seem impressive is not brave. They are unreliable.
Withdrawing is always allowed
Consent can be withdrawn at any moment, without penalty or argument. A dynamic that cannot be ended was never a dynamic at all.
Understand this before you write to me, or do not write.
