Punishments in BDSM often get talked about, but it’s something that’s often a little misunderstood, especially from newcomers.
Experienced subs or Dominants might talk about being punished, or punishing their subs.
If you watch BDSM clips, or read descriptions, there are some common tropes which come up.
Often that the sub is being punished. This can be for something like being untidy, not cleaning up properly. It could be for something seemingly minor, say, not using capital protocol. Forgetting “Good night” or “Good morning” messages, whatever.
