Walk to a picture of a man enslaved.

You walk to a painting which shows a single man down on one knee, bowing his head to an unseen person. He wears a collar around his neck and has his hands tied behind his back. Moreover, his cock seems to be encaged, which makes it look rather small and insignificant. And certainly useless.

You stare at the picture, wondering how the cage works and how it feels. It certainly prevents an erection. Probably feels a little heavy, pulling the cock downwards. But you wonder what it does to the arousal of the person wearing this confinement. Can he feel any arousal at all, or is the sensation of arousal connected to an erection? Is it painful, you wonder? One thing is clear, the man is not able to touch himself, nor to find any way of release in this situation. If he can feel arousal, it will most probably drive him crazy and make him do all sorts of things to find at least some kind of deliverance. And he won't be able to orgasm at all. Plus, it must be a maddening feeling to be reminded of your cock the whole time, feeling the cage's touch, while not being able to do anything with it.
