Female led relationships discussion

I need my Wife to keep me locked up for long stretches (months, years, yikes!). We have a device I think will handle continuous 24/365 lock ups, but when She misses feeling me inside her, she lets me out and allows me to cum. We’ve tried dildos, but our current ones are either too big for her comfort, stinky, or both. I ordered one closer in size to mine that is 100% medical silicone, but I’d like a way to attach this smaller/average sized dildo to my device without the hassle of putting on a strap-on harness. I was picturing a steel ring (for the dildo) with some kind of rubber ring attaching to the cage and another attachment point for the base ring. The easier/quicker it is to attach, the more likely she’ll be satisfied in the moment and keep me locked up. Hope that makes sense. Any advice is welcome.
