CB Range discussion

I recently got a cb-6000s and noticed that I can easily pull my penis out on its own if I choose. I am using the second smallest ring along with the smallest spacer. I make sure to draw both my penis and scrotum back as far as possible, although once it’s in place, they naturally settle into the position shown in the picture. I resolved the blood flow issue that might have been visible; my scrotum looks a bit purple now. There is a snug grip around my scrotum, but it isn’t painful unless moved quickly in one direction or another. As for size, I seem average: about 3 inches flaccid (perhaps slightly under) and 5.5 when erect. Looking at the image, I don’t completely fill the tube, but if I urinate with the hole aligned closely enough, dribbling shouldn’t be an issue.
