It depends on a few things but as long as you are not in pain then I say keep wearing it. I have had my cuck in a cage for weeks at a time, but I was removing it each day for cuck to clean the cage, and I would inspect his micropenis and balls quickly to make sure there was no injuries. Once done, and he confirmed he was not in pain, the cage would go back on. Typically about 30 minutes to an hour a day for the "inspection."
Most difficult part for him was sleeping with it on, so I would usually do morning inspections.
