Introductions discussion

Hello, I’m a married man who identifies as submissive, with my wife being quite traditional. I really enjoy role play but feel that maintaining it in real life would be tough given work and family commitments. My goal is to have her discipline me when needed and take charge of my sexual side. We currently engage in some denial activities where she gets release while I remain denied for brief stretches, all on the honor system. I want to experience being locked up so that she has full authority, yet this prospect also fills me with apprehension. For myself, I believe it’s my craving to be submissive and the thrill of humiliation that fuel my interest, though there seems to be another layer involved that I can’t quite identify. Any insights into the psychological side of what draws me in would be greatly appreciated. Thank you
