Chastity and orgasm denial discussion

Hi everyone, I’m a newcomer with a quick query. Apologies if this is in the wrong section.

I’ve been wearing my chastity device for quite some time now—about two weeks straight, taking brief ten-minute breaks to clean up here and there. Now that I have a new master, I’ve decided it’s time for an upgrade, so one is on its way. As a grower, the new model should be shorter and fit me better, which makes me really excited.

I know some submissives worry about their cock shrinking after long periods in lock up, but can you actually get used to wearing a cage that’s too short? Or is it just impractical? I’m asking because the idea of going even shorter appeals to me.

So here I am seeking your wisdom. Does anyone have experience with small cages that are smaller than their flaccid length? For reference, this new one coming my way measures 5cm in length. Aside from that, what lengths do you all usually prefer?
