Laura I like this approach from another topic. If a girl wears a chastity belt it's assumed she is desired, so her "assets" must be locked.
I don't like much my "assets" are locked,but it makes sense.As I said,being unlocked because they think l'm not pretty enough to attract men or women would have been very hard for me,emotionally.
Angelina the general approach lies with the parents. it always depends on the character of the daughter and the attitude of the parents. also parents have different reasons why they want to close their daughter, that can have to do with the exterior of the daughter or also with the behavior
But in these case,it is mainly the parents' decision,they decide it for her,not convince her she had to wear one.
In your case,if your father hasn't decided it for you when he caught you self-pleasuring(so,according to your post,he did this due to your behavior),do you think he could have convinced you to wear one?
