Chastity and orgasm denial discussion

As I’ve mentioned several times recently, I picked up two new devices. While waiting for the other to arrive, I’m locked in a clone of Jailbird. For my CB6000, I only had one ring available: the 2.25-inch size. It was quite loose, yet comfortable enough to wear continuously for a week or even indefinitely without issue. Right now, I have the 1.5-inch ring on this device and it’s… tough. I’m being cautious by wearing it in short sessions before switching back to the larger ring. The discomfort isn’t unrelenting; it focuses on the underside of my… scrotum…blushes…and when it hits, it lingers for a bit. It occurs both with and without erections. I think my body is just getting used to the tighter fit, but I wanted to check others’ experiences first as a precaution. The pain has dropped considerably since my initial test run, though spikes still feel like about 7/10. Will it get better? Or did I choose too small of a base ring?
