Has anyone in a relationship left chastity behind?

We have been living this way for two and a half years now. My wife initially thought I was crazy, but she grew to enjoy it over time. A little more than a year in, she started appreciating the arrangement a lot better than having me unlocked.

At the same time, while I see it as mostly a balanced trade-off, I usually prefer staying locked up by her preference. Usually. However, a couple of weeks ago I asked to be released. It wasn’t just a playful “please keep teasing me” request; I genuinely wanted out for about a week.

My wife missed having her wonderful husband back, and I wanted that fresh infatuation with my wife again. So here I am, locked up once more.

So my question is: do any couples completely walk away from this lifestyle once they are well established in it? I know many relationships have short periods of being unlocked, but does anyone decide to stop the practice entirely? It seems like once both partners get hooked on chastity, going back feels really difficult.
