Am I in the diminishing returns phase?

My KH girlfriend is worried because she sensed I’m not as aroused now compared to the first two weeks of lock up, and she’s right. She wants me to go at least 30 days between releases, but with how life is going this month, it might end up around 40 before my first release. Before chastity, the longest I ever went without cumming was 8 days. During my first 14 days in chastity, I was hornier than ever. I was leaking constantly, experiencing constant blue balls and had a full feeling in my prostate. However, it’s now been close to 30 days and I feel almost as if I had an orgasm. No more leaking, the blue balls are gone, I’m out of the chastity head space. It feels like a post-orgasm crash. I didn’t have a wet dream and I didn’t cheat. My cheap Rikers device fits well and is very comfortable, no pinching or burning, my body has gotten used to it. My girlfriend removes the cage every 3 to 4 days for cleaning and I might get a teasing session once a week. Otherwise, the device stays on 24/7. No PIV teasing for this first phase; she wants to be sure I can handle being inside her without cumming. We’ll test that theory on my release day when it doesn’t matter if I cum. There are a couple of threads that mention this situation, but I wanted to get a fresh perspective on what is going on. Do we have to adjust my release date, maybe go less than 30 days, or if we extend it longer do you think I will become aroused again? Any advice would be great as this is uncharted waters for me and my girlfriend. Thanks.
