New Member Seeking Advice on the CB6000s

Hi all. After watching this place for weeks, I finally decided to sign up! My experience with chastity is still somewhat limited, but I really enjoy the sensation of being locked and denied. I’m aiming for long-term chaste keeping down the line, though I’m currently chatting with potential keyholders about it. I recently bought a CB-6000s; before that, I tried an inexpensive metal device which started to rust, then a Birdlock Classic that was comfy but lacked sufficient security. The CB is super comfortable, yet there are two or three things bothering me and I’d appreciate some advice from someone with more experience. After tweaking the spacers and rings, I initially struggled to fit my entire penis into the tube when using a long spacer—only the head seemed to make it in (I suspect this has mostly to do with girth; I’m short but quite thick when soft). The stocking method worked much better. I managed to get nearly everything inside (just one tiny bit left out). Surprisingly, I didn’t even need a spacer because the fit felt perfect. It was very comfortable and secure, leaving no room for growth, which is exactly what I wanted. After wearing it for about two days, I noticed that little protruding part of my penis had become sore. My keyholder let me inspect it after taking the device off. To be honest, I was surprised to see a small cut, roughly 1cm long, on my penile skin where it was sticking out. Additionally, I found raised patches of skin from areas that were bulging through the ventilation holes. So, my main questions are: Should I stick with the stocking method but add a spacer to prevent more protrusion? Or should I give up entirely because this might just be too tight for me, or will it get better over time? I love the restriction and snugness, though I’m unsure if it’s excessive. My long-term goal is a custom device, but for now, I want to settle into using an affordable one. Thanks for any guidance, Sublevinal:)
