A Peculiar Shift After Release

For those who have followed or replied to my earlier updates, we are relatively new to this practice but committing for three months. I believe I am more keen on it than my wife is at the moment, though she has found things increasingly engaging now that a month has passed since our start. It took us a while to adjust to the CB6KS replica, but with help from various members here regarding ring size and spacer length, I have settled on what seems like the perfect fit—thanks everyone. My main reason for posting is a peculiar pattern I’ve noticed: when I avoid orgasm (whether through teasing/denial or simply because we can’t have sex due to the kids being home), I really enjoy wearing the device. But once an orgasm occurs, I feel somewhat indifferent and reluctant to put it back on until my hormones rise again; after that peak passes, I am eager for it. What causes this shift?
