Chastity and orgasm denial discussion

Hi everyone. I read here often but don’t post much. Lately, my wife and I have been engaging in more chastity play, though we’ve kept a specific rule: I stay unlocked while sleeping (mostly to avoid waking her up) and working (so I can hit the gym later). After running this routine for several days, I’ve seen the skin on the lower portion of my glans start to dry out. It gets flaky at first, then peels off before healing back up nicely. Usually there’s no pain or much irritation, but it has caught my attention. We’re using a Curve device because it fits me better than other options in that category given my size. I can’t think of any structural reason why the device itself would cause this issue. Has anyone else dealt with similar dryness? Do you have thoughts on what’s causing it and how to manage it? It isn’t urgent right now, but if we switch to a unit I’m more comfortable sleeping and working in long-term, it could become a bigger deal. Thanks!
