I am going to use this thread because in the forum we tend to always use the same ones, and there are many and very interesting ones.
My response is geared towards the conversation between @Jonas @Jenna and @Susan , about what will happen to the key on the wedding day.
@Jonas points out that the key has to be given to @Susan , I think it's not too important, and what is more, before the other way around, it seems a bit strange to me.
As I always say here I opine with my perspective and opinion, not from the top of an immutable truth.
First of all I consider that a husband and a boyfriend has, at least, the right to be heard about the chastity belt of his future wife. In my opinion it is very "suspicious" that a girl after wearing the belt during her bachelorhood, comes the first opportunity to get rid of it, and roundly refuses to continue wearing it. I can understand that, depending on her experiences, she would prefer not to wear it, but if her husband thinks otherwise, the refusal seems very suspicious to me. She is used to it and besides, if there are daughters and the idea is that they will use the belt when they reach the age when they have to use it, it is not very logical that in that family the wife refuses to use it. Another thing is that the conditions of use are negotiated, since it cannot be the same for a single girl as for a married one, but to refuse it flatly seems wrong to me.
But even if the girl refuses to use the belt after the wedding, it seems strange to me that the keys are given to the girl. It seems more natural to me to give them to the husband, for me anything else would be disrespectful. My parents, for example, would never give me the keys, I am not a suitable interlocutor for it, to my husband yes, even if they knew that the belt was going to be opened and he was not going to use it one more minute.
In any case, @Jenna and her nieces are newcomers, and having no tradition, there are many things they have to think about, many ideas will evolve and they have to find their own way.
