This is interesting. My wife and I usually play long term, and I've had the CBX devices, I've made metal parts for them, I've worn The Fort, and more recently I've been using a stainless steel Chinese device; each device has been more unbreakable and secure than the previous.
Several times over the last two or three years, I've had dreams in which Mrs Edge orders (or has me order), and subsequently locks me into a full stainless steel belt, sometimes a Latowski-ish, other times more like a CS-100, but always a full style belt, going around my waist. In the dreams she tells me that this will be a permanent arrangement. I know (in the dream) that I won't be able to "cheat" the belt by having a ruined orgasm in it, the way I can while wearing the cages.
I usually wake up from these dreams feeling *very* anxious (it's the word I've used to describe it to her). I'm not having a panic attack, but the anxiety that I feel is probably a factor of feeling a loss of control.
Interestingly, in our waking lives, we both find the idea of permanent chastity and denial very hot, so I'm not sure why I get anxious and nervous in the dreams. I have them every few months, and have not seen any pattern to when or why.
