Silly questions from a guy

Hey, folks! I’m a 30-something-year-old guy who had a couple of questions for those that have spent more time around female chastity than I have.

1- How long can a girl realistically stay in a belt, assuming it’s comfortable? How often does it have to come off? 2- Has anyone worn a metal belt through airport security in the United States? I assume it would go off and she would have to explain it.

Thanks for your time! Love you all.
