I do feel that most people, in this society, expect guys to do and like manly things, like being interested in sports, cars, and openly discussing porn or something like that. Personally, I am not interested in sports, but I am interested in games with stories. As for cars, new model every year, so I'm not going to bother keeping track of them, even though I like computer and they come out every year, I stick with one pc, and one car, for many years, and I'll be happy. Basic computer and car is for me. For talking about our personal sex life, I rather discuss that with a woman who I'm in a relationship to get closer for when we're ready for that time. Talking about ideas with other guys isn't a clean feeling, so I'd rather just not tell them anything.
As for chastity, sure the belt and cages might tug and pull on guy parts, but I see it as a symbolic meaning, showing that a guy can be trustworthy and faithful for their partner. Another good reason is to stop self pleasure so often that they give themselves rashes or distracting themselves from life goals and chores. Final reason, the guy and girl, of a couple, wears the belt and only takes it off each other to enjoy each other's company and only enjoy their freedom if in the intimate moment with their partner. The last idea falls under faithfulness, but also kind of sounds like a game/foreplay when I reread this paragraph for errors.
Oh well, whatever the reason for chastity, as long as you're safe and it's consensual, do whatever you want with your personal lives. There are still many things I wouldn't want to talk about in public regarding chastity, but I do believe I would keep my device for at least another 10 years.
