Chastity and orgasm denial discussion

I just got the CB6000 and was surprised by how hard it is to get inside that tube. I had a CB2000 back in the day, and getting into that cage was pretty straightforward without needing any lubrication.

So, what’s everyone’s take on using the CB2000 for long-term chastity? One of my past problems was pulling out the rear end too easily. If I wore it locked for about a week, once I took it off and got an erection, the skin around the glans would actually tear up, leading to pain and scabbing (you can guess why). I believe this might be prevented if my partner removes it twice a week for cleaning and stretching. Has anyone dealt with that same problem using the CB6000?

Also, I’ve never owned one of the Curve models, and honestly haven’t heard much discussion about them here. It seems like most people prefer either the CB3000 or 6000. Thanks!
