Chastity device discussions and reviews discussion

I am hesitating about buying a chastity device to stop myself from frequent jerk off, but I cannot have anyone nearby who can keep the key for me. I have no self control at all about masturbation so I can’t just lock up my bird with the keys readily available. Do you recommend I buy a chastity device to manage my masturbation habit? Would it work? How do you store the key for a certain period of time when no one else can keep the key for you??
