Do I need to re-wrap theraband in every set?

A newbie question. I am hanging 20 minute sets. After hanging a set, If I leave the theraband wrap in place, the glans gets filled with blood whereas the shaft remains strapped up giving a base ball kinda look. Does it mean that for every break between sets the theraband would need to be removed and re-wrapped for the next set?

Thanks for your comments guys.
