Mature Metal discussion

I’ve been experimenting with self locking for a couple months. However I can’t seem to get the cb-6000s to fit while being secure, I can always pull out the back. Since I self lock there is no downside to cheating. I’ve read that the some men can pull out of the jailbird but then cannot get the ring off their balls, and cannot reinsert. So the questions arise. How effective is the anti pull out pin for the jailbird, and can anyone realistically live with the pin 24/7? Is there any way to make the device more secure without a piercing? I know that no device can truly be 100% secure, but any tips on maximizing security would be great. Any info would be appreciated, Thanks!
