I like subtoy’s response. It’s about what the woman wants. My Queens loves the look of my penis trapped inside of a cage, balls purple or blue from both chastity itself, and the additional pooling of blood in the genitals caused by the device (just make sure it is not too tight!). It does not matter if the cage is plastic or metal. I have to say, the look of my penis in a ringed metal tube and my testicles popping out underneath is so much sexier than the naked penis.
I also have to agree with Richard, Roadrunner. The point of the “enforced chastity” is to affirm the WILLFUL exchange of power. My wife has thanked me more than once for giving her the power over my orgasm, and the key to my chastity cage. She knows I love her to the point I would give up my “right” to orgasms and even full erections to make her feel good. If the situation were reversed, and she offered to wear a female chastity cage and give up her right to please herself to me, I would be honored and turned on as well, but it happened the other way around, so I am happy with that.
An unknown side-effect of wearing a chastity device is the constant sense of arousal you develop, especially the longer you go without orgasm. With self-control only, you get some arousal from your own mind and the physical need to ejaculate. But when your penis is in a tube, you are reminded of this situation more often, AND the tube itself squeezes and caresses your penis as you get hard and soft and hard again. In fact, this effect is so intense at first that newbies to chastity usually have to slowly build up the ability to withstand it by wearing chastity for a day, then a day off, then 2 days, a day off, and so on. Otherwise it can become mentally overwhelming to be that physically frustrated.
It’s not about a lack of self control or the woman’s faith in our case. It’s symbology, aesthetics, and additional stimulation (mental and physical). After spending the last last two years inside of a chastity device (on and off), I’m almost to the point I want it on 24/7/365 with exceptions for cleaning and those times my Queen needs my penis for her amusement (whether I cum or not is irrelevant). It’s about her. If a woman has to put a man into a chastity device to keep him faithful, one or both of them have issues that need to be resolved before any kind of domination play happens.
