Introductions discussion

Hi there. I’ve experimented with enforced chastity for quite a while now. My collection includes a CB6000s and, more lately, a Holy Trainer short model. The recurring issue has always been locating a keyholder or girlfriend who is keen on keeping me locked up long-term. Previous keyholders were casual; they’d put me in the cage for brief periods, but since we didn’t cohabit, I missed out on that constant teasing which adds to the fun of chastity. However, I feel like I might have found her. I’ve been dating this woman for three months, and we’re essentially living together now. There were a couple of occasions where we discussed denying me orgasms. She wanted to see who could last longer without sex or ejaculation. She claimed she’d win easily, and I believe her. Furthermore, she isn’t shy about rejecting my advances when I try to initiate intimacy; if she’s not in the mood, she’ll shut me down firmly rather than giving in just because I want it. Then, a few nights ago after we had sex, she asked again how long I could manage without cumming. She followed up by asking what I’d think of being allowed only to climax on Christmas Day and her birthday? I mentioned enjoying pleasuring her while denied, which really appealed to her. It was surprising; did I finally find a woman who asks ME about chastity rather than the other way around? I believe she would make an excellent keyholder. I don’t want to overwhelm her by suggesting we lock me up if she finds it too strange, but she seems open to some play in this area. What do you all think and what’s the best approach for bringing up chastity with her?
