CB Range discussion

I’m new to the world of chastity and have had just enough experience under my belt to know I want to sign up for more! I’m fortunate to have a partner who is very open-minded and willing too:(

I own a cb6000 and have worn it several times. Recently, I wore it for periods of 30 hours and 12 hours. The issue I’m facing is that I am constantly packed tight from wall to wall and end to end while locked up. Some of my skin bulges out through the side vents on the right-hand side only; weird, I know.

After wearing it for 30 hours, I took it off and noticed he smelled a bit funky. I also had sore patches that needed healing time, and my balls were achy. The ball ache is partly due to a benign cyst in my right testicle which I knew about before starting chastity. After the 12-hour wear, I still had sore patches, but there was no bad smell; clearly hygiene matters if he stays pressed against the cage walls all day:(

So my question is, would a metal device like the penis fence from the website below work well? It isn’t as wide, but because it has such an open design, it should be more hygienic. However, I am slightly worried about the areas of my bits that are pressed against the metal constantly. I’ve also come across devices called NoPacha 800 and 900. They look great too and seem to offer plenty of width. The length of the cb6000 isn’t really a problem for me; I don’t mind that kind of confinement.

I don’t feel ready yet to spend big money on something from mature metal, although I know many folks rate them highly here. I am also curious about devices oneBay seem to offer as replicas of the ones from the above website but at a much lower price. Any advice would be appreciated?
