Nothing keeps me captive!

How did you know? I can relate to the original posting, as I had the very same problem too for more than a decade that I was able to escape most devices. Those that I couldn't escape (due to an urethral insert) were unwearable. Only recently I got a full belt (google EMCC chastity, the expensive version with conical locks) that is both wearable and secure when I combine it with a flexible urethreal insert. If you are pierced, you can connect the piercing to a lug inside the penis tube. Then it is truly inescapable! You need to unlock both the waistband lock and the penis-tube lock to get it off. There's no weak point in the tube that you could destroy with tools without cutting your penis. When the lock corrodes and gets stuck, you are seriously fucked!
