Chastity and orgasm denial discussion

I recently purchased a CB6K and expect it to arrive next week. My wife is thrilled to start exploring the idea of locking me up. Currently, she sees this as something we can do occasionally for enjoyment rather than over long stretches, though that could shift if she grows fond of having control. One thing I’m wondering about is how chastity impacts your ability to achieve an erection once you’re released. She definitely wants me locked so I can’t cum without her permission, but she insists that when the time comes, my cock should be able to get hard again. I’ve read stories suggesting some men struggle with erections after being unlocked for a while. Any thoughts or personal experiences would be great. Cheers.
