Chastity device discussions and reviews discussion

Hi there! I’ve been rocking my CB3000, but was advised to switch to a metal one. After thinking it over, I bought a lovely unit called the Arc, plus an extra ring in another size from toys4 naughty boys…very fitting if you ask me. The price was fair and delivery took just two days with simple packaging. Anyway, eager to get this new piece on once my current CB session wraps up, but I need some guidance regarding the urethral insert. This is all new territory for my pee hole—I could use a bit of advice here. Should I apply lubricant? How long can it stay inside? What’s the cleaning routine and is it safe overall? The Mistress made me get an insert…so really no other option.
