Introductions discussion

Greetings everyone! This is my debut post. I’ve been following the community since January, but never joined in because I wasn’t wearing a cage yet. Recently, I decided to give it a try and bought a CB-6000. I’ve had some experience with it now, both for short periods and overnight while sleeping. It’s hard to describe just how amazing that first time felt! Beyond the erotic side of controlling orgasms, I’m exploring chastity because I believe it will help me serve my wife better in all aspects of our life, letting her take more sexual focus. In the little time I’ve worn the CB-6000, I haven’t quite found that perfect balance between security and comfort. It’s a bit of an impediment even though I can remove it if needed. The second lowest spacer works for me, but I can only go down one ring size from the largest option. If I try the middle-sized ring, I’m totally secure, but it hurts terribly. Also, my penis doesn’t seem to slide all the way into the cage; there’s still about an inch of space left at the end. Looks like I’m more of a grower than a shower! Any tips? Should I just be patient and work down to the right size over time? Would upgrading to the newer, smaller cage for my CB-6000 make sense? Thanks!
