Female led relationships discussion

It has been a month since I emailed my wife with my carefully crafted proposal for ‘playing’ in this game. Time to update my blog at the Vault! We are considering getting a new cage and specifically choosing one she likes. Most options look very ‘masculine’, which I agree with. My wife also mentioned wanting to use serial numbered tags so she doesn’t have to worry about losing the key, while ensuring I can always take it off if necessary. It seems longer-term wearing is on the horizon! I recall reading about these a while back—any reviews or recommendations for using them? My wife surprised me by saying she wants to keep a lock available as well and has her heart set on having the key attached to her Pandora bracelet:D I could cut down a key and silver solder it onto a charm, but do you have any other ideas?
