Chastity and orgasm denial discussion

I would appreciate any advice that anyone can give me about helping my wife understand the benefits of chastity for her. Here’s a little background info: When she was on a trip about two years ago, I purchased a CB6K to try out. Nothing came of it, and it just sat in the closet for about a year. One day while we were cleaning out the house, she came across the device and asked what it was. She seemed pretty weirded out by it, so we both just dropped it. About 6 months after that, I gave her Lucy Fairbourne’s Guide for Keyholders. She read maybe 25-50% but was not really all that interested in what the book had to say, so again we dropped it. Most recently, we talked about it again, and she agreed (reluctantly) to try it. She seemed so uncomfortable with the idea, however, that I called it off. Based on her personality (all fantasies aside), I really believe that she would enjoy it if she just gave it a chance. Does anyone have any advice on how to overcome the “weird” hurdle and convince her to have an open mind about it? Any advice is appreciated.
