Totally new to chastity with one main worry...

Erections that don’t fully develop. As someone who cares deeply about his manhood, I decided to research chastity cages before buying one. They appear totally safe and hygienic (provided the cage is open enough for proper cleaning), but most importantly, they are incredibly enjoyable! However, I encountered reports of stunted erections. From what I understand, this usually happens when you get those unavoidable morning erections while asleep and still locked in. To everyone here who has more experience than me, what have your experiences been? How painful is it? Does it lead to permanent or temporary issues? Is the problem less severe than people claim? If I’m really worried, should I just remove the device before bed? Anyone offering help gets a free visit from my spirit guide for counseling.:D
