Abby82 I still need to talk to them .
Honestly, I don't understand why you, as an adult woman, accept nonsensical decisions of your parents. You are in a position not to discuss rules, but to set limits. As long as you find it okay or even good to wear a chastity belt, it is no problem to follow your parents rools.
Once you make the decision and make it unmistakably clear to your parents that you do not accept the tigh band anymore while your mother does not have to wear them, what might happen? Do you have to be afraid that they will use violence? I hope not. They can insist on their nonsensical point of view, but it doesn't take five minutes to break open a normal padlock or cut a chain. Your life, your decision - it really is that simple when you take responsibility for yourself!
