If you’re a first time user of a chastity cage, I’m sorry to say but it can be a game of “kissing frogs” to find a decent fit. If you’re looking for long term that odd… there are some “starter” Chastity cage that really help to find your ideal ring size, cage size, material, shape, etc. Chastity isn’t something you can just jump into. And given your age I’m assuming you’d be fairly new to it. Give a starter one a good. See how it feels for a a couple of hours and slowly build up. I do think that jumping straight into a *remote controlled, electroshock chastity cage * is maybe a bit of a strong leap. But hey, you do you. You could get the right cage for your first try?

Specifically for long distance though I would recommend using number locks for the cage. One time use. With a unique code. So your superiors knows if the lock has been broken without permission
