Female led relationships discussion

Four years ago on impulse I asked my wife to give chastity a try, and her agreement surprised me. We played for about three months. Usually she kept me locked for three or four days straight, then gave me a few days off. Being caged felt like bliss. While doing household chores, I read Around Her Finger which suggested that service-oriented behavior would improve my odds. My requests weren’t excessive. One day before heading out, after being locked for five consecutive days and sinking into sub space, I begged her to let me lick her pussy. She looked puzzled and said what I really needed was a good fuck. She pulled out the key, unlocked me, and told me to wash her cock. She mounted me and I finished quickly. After about a week of being free, I asked if she wanted to continue our dynamic. She replied that being a keyholder wasn’t for her; if I wanted it, I’d have to fly solo. My heart sank, but I felt she needed time. Now, four years later, my desire to be locked has grown stronger. The other day I asked if she would ever return to chastity and got a smirk—better than a no! She has been the dominant one in bed for us; we usually play about four times a month. We are both 54. It seems she isn’t comfortable being dominant outside the bedroom, which may have created an uneasy pressure extending beyond our private space. Although she did tease me often while I was caged by grabbing the cage or rubbing it with her knee before I left for work. I’m puzzled about how to proceed.
