A query regarding extended denial cycles

My fiancé generally denies me in cycles of two to four weeks. The cage is removed several times a week for PIV or other random reasons, but I am never allowed to orgasm. She has always required PIV for that emotional connection. When we met, she was extremely vanilla; now she constantly tries new things and broadens her horizons, though at a fairly slow pace. We just started using a strap-on for me to pleasure her with. Because the positions are similar to those in normal sex and our usual PIV intercourse, she has expressed that she is satisfied by using the strap on. Her satisfaction was so great that she brought up leaving me locked up for longer periods without an orgasm, while also not taking the cage off for any reason. She wants to keep the lock on continuously for weeks. I have always mentioned my fantasy of having one orgasm a year on our anniversary, but I’ve never even come close to making it past a month before starting to beg for release. On June 1st, she told me we are going to start with a minimum of three months at a time. But she plainly stated that if she can go three months without giving in and letting me orgasm, then more likely than not, she will transition straight into once-a-year denial. My interest in chastity started as a fetish, but since being with my current fiancé, it is no longer just about the fetish. It is about the emotional connection and the effect it has on our relationship. The first week of lockup is usually pretty easy for me, but by weeks 2, 3, & 4 I am so horny that I’m begging for release. So my question is this… (sorry for the long background) As time goes on will I become more or less horny? When you read fetish writings they make it seem as if every week adds to your horny desires. After two weeks I am so horny that I can’t imagine being denied for three months. She does tease me daily and keep me constantly on edge. Does the horniness ever subside and just become the norm, or does it continuously grow with each passing week?
