Chastity and orgasm denial discussion

We’ve had the Gerecke Desire for some time now and it’s been working well. The only downside is that it contains metal, which makes wearing it while traveling overseas a bit tricky. My wife/KH has trusted me to behave during my trips so far, but as things have moved forward, she isn’t too keen on letting me go unlocked unless I’m under her watch. Because of this, we’ll likely need to bring out the CB-3000 again for when I fly next time. The issue is: can I travel without triggering the metal detectors? I am departing from the UK and visiting two other European nations, and I want to avoid any embarrassing situations in security. I possess plastic locks as well; however, due to their bulk/mass, I’m uncertain whether the scanners will detect them. Any help or advice would be appreciated (since my wife really means for me to wear the CB). Cheers, Locked4her
