What a great invention ! these gummy cock rings are GREAT so soft and streachable you can wear them around the head of your cock,mid way down the shaft of your cock or at the base of your cock,intersting when you piss with it in place and even better when you cum, shoots my load out fast and far,my lady loves the feel of the little nipples on the thing.She makes me wear the ring around my balls for a few hours before transfering it to the cock head for her sexual pleasure.I dont know if they wear out but I will order more.
