Need help with ideas

My wife is needing some ideas on what things to do for dominance in public and in the bedroom. She already locks me up in public but wants ideas on certain words or cues to use in public to make me obey certain ways but not obvious, she also needs ideas on how to decide when and where to put the cage on or off or punishments/rewards to use for disobedience/obedience.

We are unsure of what words or cues to say in public to be secretive but her still be 100% in control of what I do/say.

We thought about using a point system to decide how often the cage is on or off like below so many points cage is on all the time, low points cage is off during sex but no orgasm, mid points cage is off during sex and only orgasm if she decides, and high points cage free all the time. Anyone have any ideas on what to use to count points like tasks or something?
