Chastity and orgasm denial discussion

I’m like most of the relationships I have read about here and abroad, in which I was interested in it first and tried to get the wife interested. She kind of likes playing the game, sometimes more than others. She never truly gets into it. I would love to see her really take control. She’s younger than me and I think sometimes timid. I did a little research and found an interesting book on the kindle: A KeyHolder’s Handbook: A Woman’s Guide To Male Chastity by Georgia Ivey Green It had really great reviews and a few places recommended it. I bought it for her and sent it to her device today. I haven’t read it but she seems interested in it. I’d really like her to just lock me up permanently except maybe a few ruined releases every blue moon. There is also a follow up book I might get for her after she reads this one and another on FLR, by the same author all with good reviews on Amazon, which is actually a tough thing for these kind of books. I was surprised to see 27 positive reviews on this book, that’s practically unheard of for this kind of book. But I’m curious is there anything else I could get for her to read? I’ve tried for awhile to get her interested from my perspective, but I don’t think she’ll ever understand it from my perspective. In this particular book it’s from a Female who is dominant, but also understands and explains the male psychology of it all and builds up the woman to be confident and take control. I’m hoping this helps but also looking for similar kinds of books to provide her. I figure helping provide information from someone like who she could be would be the best way for her to learn, or at least decide if that’s what she really wants. I don’t know if on one hand she may not really want that, which I could deal with, or if it’s the other she’s afraid of going to far and causing a problem. So I’m hoping some explanation of the male psychology behind it can help her understand that there really is no “too far” for me. I peaked at the first couple chapters and it even had some suggestions about finding and communicating limits and such. Anyway, any additional advice would be much appreciated. I’ve kind of tried self chastity for awhile and that does help me some, but in general I just can’t trust myself. It never fails I will have a weak moment at some point given enough time (usually less than a week)
