This is actually very similar to my reasoning to wear the cage myself. I wear it between a few days to weekly, but take it off if I'm ill for the weekend. The best reasons to keep it are for reducing physical harm/rashes to your skin, distracting yourself, and fulfilling other priorities.
I know Catherine and Vanessa's brother are allowed breaks for self pleasure, so it's fine to reduce it, plus holding back gives a better stronger feeling by the end of the week. Back on topic though, there are padlocks with timers on them, safe boxes with timers, and whatever you can find online. Until you get into a great relationship and explore each other's kinks, I wouldn't bring up the chastity idea before then.
Prepare safety measures, like spare keys, bolt cutters, or going to the ER - Emergency Room (good luck with explaining that one). Make sure you never cut off circulation and practice wearing for up to 10 minutes, 2 hours, 6 hours, then 1 full day. From there, make it a lifestyle if you need to, but never jump into a new belt without proper fitting first.
