I have it on all the time. My wife, however, doesn't like the idea of giving me strong electric shocks and her bull is a sadist jerk, so I had to carefully try higher levels of shock all by myself.
The lowest levels my wife is willing to apply can sometimes inhibit erections successfully, but some other times it feels rather exiting. Now mid high levels can already be literally painful enough to ensure a good shrunk penis state. The point in using it is to apply the shock whenever I feel excited in order to ******* and break the link between stimulation and whatever technical erection is possible with the size of cage I wear. So it goes well beyond the purpose of a simple cage. I got it from a website called houseofchastity.com and it comes in 2 sizes. Not sure they ship to the USA. Now, back to the shock levels, the highest levels are pretty distressing - and that's me. That is, if someone in use of the remote gives you no alert you'll get a real shock and you won't get your dick up for a long while. The difference with the old conventional cage I had before? Once you apply electricity, the cage feels more comfortable and less torturing. Obviously, because you don't want to get your dick back to normal size. But I wonder whether the electric shock could completely reduce my libido and sexual excitement altogether. I will also need to find someone else other than my wife who can administer the remote randomly. If your wife / gf can do it, then you're lucky.
