Chastity device discussions and reviews discussion

I’m using a birdcage right now that feels quite long for me, which leaves nearly an inch of space when I’m flaccid. This means my erection reaches about halfway full during arousal. It’s both pleasant and annoying at once because it prevents a fully hard state, while the cage continues to push my member downward without causing any pain. I’ve been reading up on how to size chastity devices properly, and many sources suggest they should be roughly an inch smaller than your flaccid length. So here is my question: What factors contribute more to horniness, frustration, or pleasure? I’m considering switching to a tighter cage so I stay maximally frustrated and horny simultaneously, which would help my good lady gain even greater control over me.
