You can't for awhile. That's part of the fun, the sensation of my piss trying to push past my sphincters and desperate to relax to relieve myself, I do let a little leak past but it flows down to the clog and stops with nowhere to go. It expands my urethra to a long rockhard tube and starts pushing back inside my bladder. Eventually the urges stop and everything equalizes until about 1-2 minutes later, my gut starts spasming to try sending piss out again. And so it goes until a little passes between the glue and urethra. It starts to peel the glue away and trickles until I release it fully. HOT AF.
