Clamping, how tight is too tight
Hi, I am not a PE newbie, and decided to try clamping. I went to walmart and picked up the cable clamps and ACE bandage, I could not find any of the magnetic wraps discussed.
My problem is that when I start, I lose my erection after 5 or so minutes, the blood is flowing out of my penis. However, being a newb to clamping, I am scared I will clamp too tight and run into problems. Any suggestions would be appreciated.
