Need Help With Simple ADS

Hi, today I tried using the Simple ADS. Wrapped my cock with some cotton cloth and used two theraband strips, cut down like the instructions say on the video area.

Felt good but I think I’m wrapping too tight because my glans was getting cold. So I took it off as soon as I felt that, about 15 min into the trial.

Does anyone have a special technique to wrap without cutting circulation? Or more a trail and error/ experience?

I also used the simple ADS in the morning to hang for 20 min @ 2 lbs, felt great, then jelqed for 20 min. Tomorrow ill try it again but ill do the jelqs first.
