Full Belts discussion

Hi there, I’ve been using a solid metal front-to-back masterpiece device for over twelve months now. I’m giving up on Dr Mende because his replies take roughly three weeks, and by then my belt is likely packed away in frustration. The rear opening seems to be the issue; my anus sits too high. He suggested curving the front shield near the tube and bending the pin-entry area backward. I tried that, which helped slightly. After remeasuring as instructed, I still get the same numbers. I’m also confused about his description of where this belt should sit. I can place it quite high and tighten it significantly—so much so that walking becomes painful. It is definitely below my waistline though. Normally when I wear it, the back side feels a bit loose, leading to pinching. How tight should it really be? Should I toughen up and keep it super tight? (If that’s required, I can manage, but the anal positioning would still feel off) Thanks Tyler
