Chastity and orgasm denial discussion

Hey everyone, I’m sorry I haven’t introduced myself yet. I’ve been pondering if and when to share my story here. Now is the time. So I was intrigued by the idea of chastity ever since I first heard of it about 7 years ago. I experimented a bit with my then girlfriend, but it soon turned out she didn’t really have a serious dominant streak and we dropped it. Now I’m engaged to my girlfriend who I met in 2015, we’re happy and deeply in love, we’re a power couple, we have founded a company together that is growing fast and most of all: whenever we play a little bit with chastity or with her dominance in general, she is just amazing! She can read my mind, she is frighteningly clever, I can’t keep any secret from her and when she wants to ruin my orgasm I would never even once have to warn her that I’m about to come. She just knows my body better than I do. Here’s the hook: we can’t really play a lot. At this point, it’s been 15 months since I attached straps to our bed for her to tie me up and use my tongue when she wants. She hasn’t done that even one single time since then. The reason is not so much her reluctance as an attitude by itself, but rather the fact that we work together. She’s explained to me that if I was locked up in the office she would actually change her behavior towards me in front of all our employees. She wouldn’t be able to help it, because it’s not a game to her, she actually feels she owns me when she holds my key, and she can’t hide that she sees me as her property then. But obviously she would have to. And she needs me as her equal partner at work. So, coming home after work, putting on the cage and removing it in the morning is not really an option as probably many of you will understand. I’m looking for at least a handful of periods of playtime a year that last more than one, ideally two weeks, during which I’m absolutely helpless when she holds my key and starts treating me as her property. So far, the longest we have ever gone was 3 days. Now, this thread is called „reluctant girlfriend“ for a reason: she has started justifying this problem instead of longing for a solution together with me. She says things like: the cage I have (a beautiful jailbird) is too medieval and unpractical anyway. And that goes for all of these cages, they just don’t appeal to her as a designer of slim and feminine shapes. Plus, she wouldn’t want to cuddle with me while I’m wearing it, she says it bothers her to feel the cage. And she says she finds it very stressful to be my keyholder. She doesn’t want her authority challenged at all, but obviously, if we have just the weekend as a session, my fetish makes me subtly test her limits: what would she do if I misbehave? Would she add chastity time? Or punish me some other creative way? Tie me up uncomfortably and leave me there to suffer? She could also say that she refuses to play with me if I challenge her, that would serve as an effective threat as well. But instead she complains about the fetish altogether, makes me feel like I’m a bit annoying (I haven’t even mentioned this problem with her in quite a long while now) and she seems unable or sometimes just reluctant to pursue this any more. I’m telling you all of this in the hopes of getting advice, maybe based on some experience of your own - if you’re going to criticize my behavior in all of this, just know that I’m already aware of most of these things, I think. So please try and make it constructive criticism. Thank you very much!
