Initial thoughts and sizing questions for newbies

I’m new to both the site and the practice of chastity. Here’s some context for my queries. First, I checked out a bunch of different devices. My main requirement is an extra-large A-ring. Don’t mistake this for boasting…my situation isn’t about being exceptionally large overall; it’s just how things sit down below. Definitely more “grower” than anything else. Following the Holy Trainer method, my measurement came in around 80mm. Most options were capped at 50mm (or two inches). CB-X now offers their 2 1/8 and 2 1/4 rings as individual components, so I picked up the larger one. Afterward, I bought all the necessary spare parts to assemble a full The Curve setup, which ended up saving me money compared to buying the complete device with four rings that would never fit. Once lubricated, sliding into it is manageable and then it feels quite comfortable. People have mentioned my testicles are substantial, so any cage lacking a split ring design wouldn’t work for me. The primary reason I chose The Curve was its extra width. My flaccid size sits around 1 1/2 inches in diameter, but I don’t have enough length to fully occupy the space. The issue arises during an erection: I become thick enough that I get jammed near the front of the cage rather than filling out completely. This tends to push the device away from my body and causes discomfort. I’m considering switching to a CB-6000 cage because its downward curve is less pronounced. It also looks odd having so much empty space. Any thoughts? Thanks.
