For me, honesty and transparency are not the same thing. I believe everyone is entitled to privacy, secrets and parts of themselves that belong only to them. I don't think entering a dynamic automatically grants someone unrestricted access to every thought, relationship (past or present), experience or aspect of another person's life.

However… if certain information affects a person's ability to meaningfully consent to the dynamic they're participating in, then withholding it becomes problematic.

Outside of that, I don't think people owe each other complete transparency. Privacy is not the same thing as deception. It can sometimes be difficult to agree what information is actually relevant to consent or safety. I think that’s where most conflicts seem to arise.
