Your kink is not a free pass for someone to treat you like shit.
A degradation kink does not mean someone gets to degrade you whenever they feel like it.
A humiliation kink does not mean someone gets to humiliate you because they had a bad day.
A pain kink does not mean someone gets to hurt you outside of what you agreed to.
This should not be complicated.
If you have negotiated degradation, fine.
If you have negotiated humiliation, fine.
If you have a dynamic where certain words, rules, tone or behavior exist outside of scenes, also fine.
Adults can do complicated things.
Not implied because you once got wet reading something filthy.
Not assumed because you call them Sir, Mistress, Daddy, Mommy, Owner, or whatever word makes your knees weak.
Not smuggled in because you like being called a good little slut in the right context.
Your dominant should not be calling you stupid, useless, pathetic, ugly, worthless, annoying, too much, not enough, or whatever else cuts into you, and then hide behind your kink when you react like a human being.
Especially not if you have told them it hurt you.
That is the part people need to pay attention to.
What they do when you say:
"That actually made me feel bad."
Do they care that they hit something real?
Or do they make you feel dramatic, weak, oversensitive, ungrateful, or bad at submission?
Because that tells you a lot.
A good dominant can enjoy hurting you in the ways you both agreed to.
They can enjoy the tears.
The shame.
The struggle.
The filthy little collapse.
But they should not enjoy damaging your self-worth.
Those are not the same thing.
The other is just cruelty.
Outside of the agreed dynamic, you are still two people.
Even if the relationship is not equal in structure.
A D/s dynamic can include control. It can include obedience. It can include degradation. It can include harshness, if that is what you both want.
But it should not slowly train you to accept being treated badly just so someone else can feel powerful.
If someone keeps hurting you, refuses to listen, refuses to adjust, and then uses your kink as the reason you should shut up and take it?
That is not a hard style.
That is someone using BDSM language to cover ordinary abuse.
And no, your kink does not make that your fault.
