Chastity and orgasm denial discussion

A while back I found a document on my PC confirming that over ten years have passed since I first got my wife into chastity and orgasm denial. We began with the cb3K, which neither of us cared for much due to its tight enclosure. Next we moved to metal options: she picked out the Gerecke Twister 2, then we went through two MM JailBirds that kept getting smaller. Now there is absolutely no space left for an erection, and as many people note, this creates excellent comfort. Initially, my wife had me wear a big silicone dildo in a harness above my cage so she could have penetrative sex. I recall receiving a text telling me to put it on after work and wait for her to get home! Roughly once a month I was permitted inside to cum. Over time, she stopped penetration entirely and switched fully to oral worship of her pussy, which she adores. For the past two years I haven’t gone inside her; honestly, I can say I’ve forgotten what that sensation feels like. She has no clue how long I have been denied (currently 6 weeks) and tries hard not to bring me to an orgasm, but inevitably after several months pass, a certain touch triggers it. Sometimes she uses an Njoy pure wand on me, though I find doing it myself more effective—and gives better relief. My orgasms now come with intense sensations as she has hers: I end up breathless and tingling all over, my penis goes soft, and I feel just as sensitive afterward as when I used to ejaculate normally. The ejaculation itself is the only difference. She says orgasm denial matters most to her, but I’ve never managed to get a clear reason why; she won’t elaborate further. So things have advanced steadily for ten years until my chastity has become an unquestioned yet ever-present part of our relationship. Who would have predicted that what seemed like a fun side-note to our sex life would turn into such a lasting staple?
