Difficulties with wearing a device? discussion

hello everyone I’m quite fresh to the experience of wearing my lock overnight or for longer stretches. The issue I face is when I get an erection while in my cb6000s. First off, I’m a grower type; so during daytime hours when soft, there’s still roughly an inch between me and the tip. But once erect, my shaft extends straight forward, striking the upper section of the cage rather than filling it out properly, which leads to sharp discomfort. Before I shell out for a metal model, I’d like to understand what might be going wrong with this current one. The 6000’s outer shell is fine and wouldn’t press too hard against my tip, but it felt slightly loose in terms of stability—it was small enough that it could easily slip off if pulled the right way. Any advice would be much appreciated
