Introductions discussion

Hello, Just a quick intro: my wife and I have been trying out chastity devices for about a year now. It started as my fantasy, and while she participates willingly, it feels like she’s mostly doing it for me. Everything is fine with no complaints, but since I love it so much, I hope she can find more enjoyment in the experience too. That said, I’ve been searching for reading material about this lifestyle that would suit her, as that was my entry point into it. The issue is that even though she speaks French fluently, she isn’t very keen on reading (she’s Japanese). So I looked for books covering FLR, femdom, and male chastity in Japanese but didn’t turn up much. It puzzled me because Japan has a fairly vibrant BDSM/femdom community with plenty of magazines on the topic. However, they’re all geared towards men. Has anyone here read books originally written in Japanese? Or could someone recommend movies that cover this subject without being male-focused porn? I’m particularly interested in content that highlights what women gain from these relationships rather than just viewing things through a man’s eyes. Thanks.
