CB Range discussion

Hello everyone, Even though I’ve spent a lot of time in my CB6K, 6KS & 2k devices, it seems I still haven’t quite mastered this. I want to keep using the ring I currently have (the medium-sized one), but with the shortest pin and spacer so that the tube sits very close to the ring. The problem is that sometimes when I bend over or down, my cock does a “turtle/tortoise” move, pulling back towards my body and almost sliding under the KSD G3. I’ve tried using the larger G3 model, but it’s just too painful for daily wear. On the other hand, if I use the shortest pin and spacer, the gap is so tight that within a minute or two my balls feel like they’re about to burst (and not in a pleasant way).:confused0086: I often catch myself “pushing” the 6Ks back towards me to help my cock slide further down the tube. What do other fellows with smaller cocks and a CB6K/6KS setup recommend? Thanks.
