Routine can be your friend.
No doubt, at some point in your life you have been told that getting into a routine is helpful. If your anything like me, for the first few years you ignored it completely. Then you begin to realiese it may actually be useful. Routines are actually useful basically because it enforces repetitive behaviour. Now that in itself isn’t bad, but consider this: If that routine is used (With both partners consent) to reinforce the sexual hierachy, ie who is in charge, it can be used to re affirm the messege, that He or She is in control.
For example, a recent friend of mine and I were talking about daily routines. He was saying that they have a routine, whereby every morning whilst he is locked up his Mistress uses a strapon on him, not for his or Her pleaure, but to let him know that She is in charge. So when he goes to work every morning, freshly anally fucked he knows his place is beneath her, whilst he is locked up, with his Mistress having the only key. Over time, the messege becomes more and more obvious and reinforces their positions in the relationships
