Rubber Band Trick for PE

I keep seeing things about pe and cumming to soon around this part of the forum and while its not a problem with me id still like to last longer

and if its a quicky day I end up compensating by not stopping while i cum and keep thrusting, or going at a slow-moderate pace

I was wondering if the rubber band trick is a good idea cause i dunno where but I heard of a man having his penis blow (dunno why, forgot the reason)

but yeah, just wondering if putting a rubber band around your penis to stop yourself from cumming during sex for a while a good idea or not.
