Inquiries Regarding Male Chastity Breaks and Practices

Hi there! My husband and I have recently gotten into male chastity. He’s been locked up on and off for about a month now, with the longest stretch lasting nine days. The main issue I’m facing is that I get incredibly aroused seeing him in his cage. So often, I unlock him just so he can please me exactly how I like. This means our attempts at taking breaks haven’t gone well at all. Does anyone have any advice? What’s a good length for a break-in period? Should I let him out at all? Maybe even if it’s just to have sex with me without him finishing?
