erections returning after being unlocked

So my wife and I are somewhat new to this dynamic, and she’s gradually warming up and enjoying the benefits However, she is concerned that it might “condition” me in negative ways. She feels I shouldn’t wear a cage constantly because of potential functional issues. A bit about myself: I have a very healthy libido. Like most men, I go through cycles, but performance has never been an issue. Recently, twice while locked up and highly aroused, focused on pleasing her rather than my own pleasure, she had me unlock to give what she wanted—and suddenly I struggled to get hard. I expected to need to quickly remove the ring, but that wasn’t necessary. The second time really worried both of us (as this hadn’t happened before). She suggested I had been “forcefully turning off” my response for so long that it was conditioning me not to react. Luckily, we lay together for an hour and suddenly I was ready again, leaving us both satisfied, but the experience stuck with me. Neither of us wants extremely long periods of total denial or lockup; we prefer regular access, which she enjoys especially as a way to maintain control and deepen our already healthy intimacy. I would DEFINITELY like to continue this arrangement, though we are both mindful of possible negative physical effects. Has anyone else experienced something similar? Part of me feels I was so focused on her pleasure (and I truly was) that mentally disengaged from my own body. Honestly, I had fallen into not caring about my pleasure; when she said “no, just rub me” during one of the things I love doing for her while locked up, I complied instantly without regret. However, I am concerned she has a valid point. The other perspective is that after straining and being restrained, my cock was somewhat “tired,” and initial freedom offered a chance to rest, as sometimes I feel significant pressure at the base under my balls… what do you all think? Any relevant experiences?
