Able to Release While Locked Up in Metal or Plastic?

I’m looking for some advice. I’ve owned a CB6KS and a Twister 2 from Gericke, plus a cheaper steel device that eventually rusted. No matter what I wear, I can just wiggle the lock or tube around, and presto—can cum to my heart’s content. I go for weeks until I hit a wall before relieving myself. My key holder would be devastated if she knew I could still come in. I always feel low after cumming, yet I have relieved myself after periods of being locked up. Is it just me, or is everyone else able to stimulate themselves? It feels like an unwritten rule that we all pretend to be truly chaste and wear a device because we enjoy the feeling of being locked? We’ve spent over £500 on chastity devices that are little more than decorations. Where am I going wrong?
