I'm interested in getting a smaller cage than what I currently have, and have been looking into cages with a urethral insert. I have no experience in sounding. It is my understanding that long term wear increases the risk for an infection, so I would only wear the cage for a period of 2-6hrs and remove before sleep. To those who have used a cage with a urethral tube/catheter/insert, what was your experience like? What material was the insert? Any pain outside of the normal chastity discomfort? Your general thoughts on the urethral tube?
