Chastity and orgasm denial discussion

This query appears in different forms across various boards, but I’m reaching out to the knowledgeable and seasoned members here for some clear answers. My Wife is thinking about getting me pierced, and I’m open to it, yet I’m unsure which type of piercing would suit best. Here are the factors that need to be part of the choice:

1. The piercing must allow my chastity devices to be completely escape-proof.
2. I am not circumcised, so any piercing needs to work well with this anatomy. My main concern is how my foreskin will handle a piercing. Ideally, it should keep the foreskin retracted to prevent it from getting caught between the jewelry and my cage or rubbing against them.
3. Since I travel often for business, I wear a CB6000 with plastic locks during flights to avoid issues at security checkpoints. While I’d be happy wearing metal devices when not traveling, air safety is crucial while away, so the piercing must be compatible with flying. Do piercings trigger airport metal detectors, or are there suitable plastic or ceramic alternatives? I warmly welcome any thoughts, personal stories, or recommendations.
