Chastity and orgasm denial discussion

I began with the metal Master Lock included in the CB6000 kit. It was quite bulky and required a rubber band to keep it from clanking, which became an issue when visitors came over. I also decided to wear my cage for extended durations. The weight of that metal lock tends to make the top of my penis sore due to the pressure. I picked up some inexpensive plastic locks with serial numbers from Kept for Her and they are much better. They don’t add any weight, stay silent, and are easier to conceal. Plus, there’s no key to manage. My wife simply writes down the current serial number on my lock when she changes it out. Theoretically, if you twist hard enough, the plastic will snap, but ordinary scissors or a small knife can cut through them easily too. I think these are ideal for online Keyholders since the sub can just send a photo of his device with today’s newspaper as proof via email. No keys to lose around. Honestly, at my age, I could probably pull my penis out of the cage because it shrinks up inside me quite a bit. But since initiating chastity was my own idea, doing so would only be cheating myself. The cage doesn’t hold any special meaning for us; it’s just there to give me pause before trying to masturbate and makes it difficult enough that I usually stop. What types of locks do you all use?
