I desire the cage, yet I hesitate

Roughly a year and a half back, I picked up an MM Jailbird. I had some weight to shed, so I used the cage as part of my diet plan, with my wife rewarding me when I hit milestones. It worked really well and we both enjoyed it—I dropped 55lbs and feel healthier and more comfortable now than ever… Once I reached my goal, she took the cage off, life got busy, and that was that. Lately though, I miss having it on. I do like being able to masturbate whenever I want… However, before I hit myself off, I prefer being locked up with plenty of denial, whereas after I don’t need quite as much restriction. She doesn’t seem super keen on the idea herself, but she does enjoy holding onto the key. Last time around, I used my weight loss progress as a justification for keeping it on, but this time I’m not so sure what to say (if I genuinely want it back)…what is everyone’s take? Should I just let it go or chase it down?
