I have no idea what you mean by that UNDER the penis and tongue stuff??
Rods at the side are not visible in pants, depending on the amount of excess rods the ends won’t show up either.
I mean cutting off bloodflow TO the glans not IN the glans itself. I use a stretch of 4-8lbs for now and with all of my excess foreskin I need a tight enough grip, so if something would be pressed in at the bottom (where the cs is) because of the tight grip it would cut off my bloodflow to the glans to some degree.
I mixed my stretcher with a hanging device which allows for a much greater stretch, the less pressure is placed at the bottom the more stretch I can use without cutting off circulation. Technically my stretcher can handle stretches similar to heavy weights of course then it can’t work as ADS anymore. The usable stretch is where ours differ, the bulge in the pants is probably equal.
Btw the rods I used were 3/16”(0,5cm) in diameter the diameter of the only turnbuckles I saw were 2+x that amount.
