Not Sure About This Setup

I'm in an open relationship and have been for a while now. My partner and I decided it was okay to date others as long as we kept each other informed and there were no secrets. Recently, I've started seeing someone new who's really into roleplay and bondage. We did some CNC stuff last night that got pretty intense, but afterwards, I felt guilty because my primary knows nothing about this side of me or the kinks involved. Should I be worried? Is it normal to have such different experiences with different people even if everyone consents?
