Swim Cap Question

After much reading, I have decided to try hanging to increase length. I am going to try using a “Swim Cap” as suggested. My question is this: After each set of hanging, will I need to remove the swim cap during the break, or just unstrap the weight? It will definitly be more of a hassel if I have to remove the swim cap each time and then rewrap it for a new set.

Thanks for info!

I started out hanging with a swim cap wrap and always unwrapped entirely between sets. Necrosis of the glans is not a happy thought.
