another path toward chastity

I’d appreciate your thoughts. Coming from the BDSM background, my wife and I tried male chastity with varying success. The basic problem became her increasing dislike of having to maintain the D/s relationship in all matters, not just chastity. I was basically happy with being her submissive, but the D/s was becoming a challenge for her, and simply not working for both of us, so we stopped. I didn’t help matters by “topping from the bottom” and asking for tease-and-denial, release at my choosing etc. However, I get the recurring desire to experience long-term chastity (well, weeks and months) with her as my willing keyholder. I came across some writings on a blog site “medium” by a lady called “ChastityPerkins” which suggested an approach to chastity that might work for us. She wanted to stop her husband continually wanting to do kinky play and chastity, and nagging her to do so, and proposed to him that she would indeed impose his chastity, entirely on her terms. Her terms were, put simply, that she would obtain a suitable device, and after establishing it was effective, lock him in it and maintain the lock-up until she chose to release him. Any mention of release, orgasm, or sexual play by him would result in a harsh punishment (not the “funishment” often found in BDSM play). The intention was to remove almost all involvement by her in his chastity, therefore removing the D/s relationship except in the one area of chastity. Have any of you tried this approach? Or am I just missing something obvious? re. a device, I have a JailBird, and whilst I may be able to partially escape (never tried) my wife and I regard it as effective. I wouldn’t want to go down the urethral tube route used by Chastity Perkins to guarantee full effectiveness for safety and health reasons, and I very much doubt my wife would want me to.
