question on cable clamps

I tried the cable clamp for the first time today, and it didn’t work too well. I bought the smallest clamp even though my girth is 5.4 inches. I tried wrapping a cloth around my schlong base for more tightness, but I lost the 120% erection that I guess one is supposed to maintain after more than 8 minutes of using the cable clamp. I’m wondering if the erection level has to stay at 120% or 110% throughout the whole time the clamp is on? If so, then does anyone have any idea how to make it tighter? I think a rubber band would be more effective.

I wrap a a cut up sock around mine. You have a bigger girth than me so I am sure these would work for you if they do for me. You just need to figure out how to wrap it. I have to stimulate myself most of the time while clamped to maintain the fullest erection.

You can adjust the size of the clamp by wrapping it in electrical tape.

Can somebody explain me in easy english (lol)
