Cock cages with sounding

[bps]

I don't know anyone who has used these, but I have seen pictures of them on men. My question is a little off subkect but I don't know of a better place to ask this. Don't they hurt and possibly damage the penis if a man gets an erection?

my curiosity about cages with urethral plugs/tubes goes into this territory too. But somehow I envision that a device that basically skewers your flaccid dick wld more effectively thwart arousal in the first place, which I do find really appealing. To me a cage that can do that is doing its primary job perfectly! I’ve only tried one cage but it certainly doesn’t keep me from getting aroused
