Chastity and orgasm denial discussion

Greetings everyone, I’ve shared that this is my introduction on my profile, but I recently opened up to my wife of over fifteen years about wanting to live in chastity and have her take the role of Keyholder. She was quite puzzled and unsure. Being extremely traditional, it wasn’t easy for me to bring it up. Fortunately, she didn’t just say no outright and has stayed open to discussion. I asked if she’d read a book to help clarify things, and she agreed. So now, Georgia Ivey Green’s guide is in her hands. We talked more about it yesterday evening. She says the reading is helpful, but uncertainty remains. She still struggles with understanding why this appeals to me so much. It doesn’t click for her that denying myself pleasure actually benefits hers over time; she can’t quite grasp how hard it is for me to avoid masturbation even when she’s right there and available. To her, it feels selfish, yet she considers herself a kind person. However, last night she pointed out something important: during our engagement period, I satisfied her well while she rarely returned the favor. It’s a long story, but our conservative background meant we waited for actual intercourse until marriage, though she let me use my fingers and mouth on her. She gave me two or three handjobs in those eleven months. Last night, she mentioned that didn’t bother her at all, so perhaps this new arrangement won’t either. I see it as a sign of progress. She also typically has a very low sex drive, which makes her worry I might suffer greatly if we proceed. I tried explaining to her that suffering is somewhat the point. She also appreciated that since sharing my thoughts and reading, she finds herself thinking about sex constantly, suggesting this could have lasting effects for both of us. So far, I’ve persuaded her to let me bring her two orgasms without expecting anything back in return. Last night, she even pulled down her clothes, said “I’m tired,” and turned over. I believe we are moving forward and will keep the thread updated as things unfold. She has given me permission to ask about her thoughts anytime, which shouldn’t trouble her, so I hope to have more news soon. Any advice is welcome.
