Mature Metal discussion

I’ve been wearing the CB6000S and finding a very comfortable fit, yet I can easily pull my penis out of the cage to jerk off regardless of which rings and gaps I choose. My testicles stay trapped, making it hard to get everything back inside, so cheating is definitely on the table if this continues. I’m keen on getting the Queens Keep device and wanted to ask if its anti-pullout pins are effective? Has anyone here used them?
