The only male wearing such devices I know is my twin,who may have to wear it for some time for punishment(not respecting the rules with his girlfriend,bad grades,etc...).When not wearing it,except some rules(homework and chores before sex,studies first,etc;..),he's allowed to masturbate and to have sex.(stricter limites after being punished,sometimes).
Twin,so same age,and we're not punsihing each other,it is our parents who punish us.
About chatsity belt and submissiveness,I agree with you,I don't think being submissive by wearing a chastity belt means such women are bainless submissive.
Sara2001 If your brother starts to have a very serious relationship,is it possible that your parents want his grilfriend to wear a chastity belt(with them having the keys for her belt)until they marry?
