Introductions discussion

This appears to be an intriguing realm. I believe a chastity device could really assist me. I tend to masturbate excessively and find my self-control lacking. So, for now at least, I’m seeking something that bolsters where I fall short in restraint. I’ve examined the CB and Holy Trainer lines but haven’t quite grasped their mechanics. Surely if the penis and testicles can be pushed through a ring, they should be able to push back out? I pictured these rings having some sort of hinge—similar to handcuffs—to secure them firmly. But do they actually have that feature? Judging by the descriptions, it seems not. I am concerned to read reports suggesting they slip off rather easily. Apologies if this sounds like a naive question. I would appreciate it greatly if you could share your experiences and let me know how it truly works in practice. Thank you all. This appears to be a very welcoming and supportive community.
