youdontknowme 24/7 chastity is not strictly necessary either. When the situation makes the arrangement more unpleasant than what you agreed to, it is a good idea to have an honest conversation with your keyholder
Chastity belts in general are not necessary. Every couple has it's own goals. I never said it shouldn't be pleasant when this is how it should be for a couple.
The question was what is necessary. Or with other words, what would be the minimum freedom that is needed. The question was not: "What would be the best comprim between security and a pleasant situation".
I for example can accept that I have to wear the belt when I am ill, others can see it differently. For me it would feel like he doesn't care for me when it becomes complicated, so he chooses the easiest way for him and just let me out, risking that I do things I am not allowed to do. Why should I invest so much effort and why should I give up such an important thing, just to make him happy, when he is not willing to take care of this gift when it's a bit more complicated to take care of it. I wouldn't feel valued and honoured but used and cheated. It wouldn't help me to get my health back quicker but that's just my opinion.
