Before this forum, Ivana wrote this on Misterpoll which seems relevant.
"My advice for you: If there are any unbelted periods for you like "free days" or time at school or anything else: Offer to your parents to give it away voluntarily! They would be so touched and be proud of you! Reduce to cleaning breaks only, don't try to cheat and try to forget your belt. The more consequent you wear it, the more you get used to it and the more you will see that your need for getting out will decrease. Believe me, it works!"
I don't doubt her experience, though I don't know if it is the same for everyone.
Amira I feel like being a servant of my body functions
Amira I don't want to do it like a robot would do it once I get the opportunity.
Yes, and I can relate to this too. Although it is locked, my belt gives me mastery over my body and its desires.
However, whatever you decide, be happy!
