I want to put myself into chastity because I'm a chronic masturbator and I feel bad for wasting my cum when my wife absolutely LOVES the taste of it. I want to be able to save it for her but am unable to, on my own
Hiii and welcome to the Mansion It sounds like you and your Wife need to sit down and have a honest discussion and see where it takes you....just my 2 cents. There is a lot of good information here on the subject on informing your partner of your desire for chastity and why. Good luck and have fun.
I'm planning to order a cage, when I get paid, and to just start wearing it. She'll have 1 key and I'll hide the other, so she can unlock me or I can unlock myself at her request
Realistically, you have to talk to her about it first. You can't just present her with a cage and a lock. She'll freak out, quite rightly. You have to sit down and quietly discuss it with her - why you want to do it, what she gets out of it, how it's all about her, not you. You're going to need to sell it as an idea. Just locking yourself up and letting her find out the hard (soft?) way isn't going to work.
You think she's going to let a confessed masturbator hide his own key? That's not the way it usually works....
