Hello, I've been trying to research this online but I've been having a tough time actually finding any answers. My chastity cage has an optional urethra tube, and I would never wear it. However I've been having a problem where the tip of me can slip to one side or another and an edge of my opening will stick out and rub again my underwear and hurt super bad. I think that if I were to wear the urethra tube it would keep me aligned and prevent that issue. However, does having the tube in stretch out your urethra? And if it does is that permanent? I don't want to do anything that I might regret in my 60s or something if it effects being able to hold in going to the bathroom or stuff like that. I know the dangerous of uti and going slow to avoid any injuries on the inside, but what about getting stretched. Thanks for your help.
