Chastity and orgasm denial discussion

Three weeks back, my KH let me have an orgasm after I’d been locked for thirty-seven days. Those thirty-seven days felt straightforward. It was the first time I did a long lock-up; usually, it’s just around ten days. I’m in the device again now and finding this round quite tough, pun intended. There’s constant arousal mixed with frustration. I enjoy it yet find the sensation somewhat strange at times. Not sure when my next release is coming up. I read that when things get hard, that’s where the real enjoyment starts. Is that accurate?
