Novices and newbies discussion

Hi everyone! I feel pretty lucky to have found someone who can keep my key <3. To cut a long tale short, I’m currently turtling -_-. My setup includes a CB-6000 with a 45mm ring and the smallest spacer available. Wearing it during the day is quite comfortable; while I do leak and am able to pee without issue, shrinking up significantly makes arousal painful, which also resulted in a small cut.

I’d love to hear what you all think about how I can fix this. If my flaccid length is 4 inches but turtles down to around 2.5 inches inside the cage (which measures 3.5 inches long and fills up nicely at first), should I opt for a HTv3 knockoff that’s either 2.39 inches or 1.79 inches in length? Any thoughts are welcome:) Just remember that I turtle to roughly the same position shown in my photos, even with the tiniest spacer:(
