Regarding your question. Unfortunately without plaster or rubber band my foreskin doesn't stay behind the glans when blood flows out. In boner situation it is tight very tight it won't go pass glans to cover it unless forced. I guess the ratio difference between flat and pumped is too big.
Yes l took off curtain ring straight away l thought it would add another barier but it turned out not to be necessary. So l slept one night just wearing hair band. It stayed in place throughout all night. I discovered few advantage of this band. First of all it gives extra buffer between very sensitive crown and it's not rubbing directly against pants mostly pyjamas during lockdown;)
My cock didn't fell off after night. New setup wasn't causing discomfort or waking me up.
Morning piss was great didn't have to bother taking it off and improved aiming!!
Twisted band seems to be good for me and somehow the size fits perfectly how did they know?

Picture from second day glans skin feels slightly firmer and dry and lm very happy hygienewise
I'm thinking of starting to enquire manufacturers to set up my own brand of glans bands
)))) worked so well for me!!
I'm a kinda DIY guy and joiner and like crafty stuff so l think that helped me to come up with this brilliant idea
All the best everyone!!
