How long works best for a chastity device and catheter?

Does anyone here use a catheter with their chastity device? I finally took the plunge and managed to get my catheter in and connected to the hole on the end of my device. It’s about 10 mm, roughly 3 inches long.. feels pretty good., just want to know how long anyone has worn one. Days, a week or 2?, longer,, any bad feedback?? Thanks. I have surmised this,, Pulling out the back is no longer possible.. Unless I remove the cap at the end to release the catheter,, have not tried that yet., still getting used to it being in there.!
