So here is a bit about why I wear a chastity belt.
I discovered chastity through fetish many years ago but I have found it to be a tool to help curb bad habits and have all but entirely lost interest in fetish over the years. My main reason for wearing is to be totally faithful to my wife. We don't do it really as a form of play or anything, it helps me curb a habit I don't want. I also notice that it helps my mood when I don't pleasure myself. It is hard to explain but there's a big difference in how I feel after intimacy with my wife vs doing things on my own, I guess the best analogy is the difference between genuine and fake.
My wife has some medical problems that limit our ability to be intimate. Typically if I ask for release she will say yes if she is feeling up to it, but it helps her feel comfortable if she has to say not right now, this works well for us. For a long time she would feel guilty even if I reassured her that it was ok, especially since I have a belt. Over time she has noticed that it does help me and has gotten more comfortable. The tradeoff is that sometimes I am going crazy and can't cool off, the belt keeps me from acting on desire on my own and eventually subsides.
It's really important to me that I don't seem pushy about getting what I want, that our time together be something we both actually want. The last thing I want is for her to be feeling unwell but giving in due to a sense of obligation. So I tell her the only obligation is to make sure I am wearing my belt when I need it. So if for example I don't have it on at the time and I ask if we can be intimate, she has gotten a lot more comfortable over time asking me to put my belt on for now.
I think it has helped us build trust so for that reason we enjoy it. We had tried all the keyholding control sort of stuff and that just didn't work for us at all. Now my wife is starting a new program and will be going to college, so she will be away from the house a lot more. We both agreed it would be best for me to wear my belt essentially 24/7 or more like 23/7 to have an hour or so break once a day or every few days. Currently I often wear it only as needed - I have access to the belt and lock but not the key, it's an honor system that I agree to put it on as soon as I feel tempted and will wear it typically a few days until she feels up to relieving me.
Regarding the type of belt I wear, I have found the Neosteel to be the most effective even though its challenging for a guy to wear a full belt. To me the security really matters, it has to stop me when I am weak and tempted and no cage device I tried can do that for me. I can always find a way out or find a way to achieve stimulation in a cage style device. The Neosteel belt holds everything well and prevents any significant friction. It's also more secure due to its construction and lock.
If the device doesn't prevent me from removing it and doesn't prevent me from stimulation then there's just no point in wearing it at all. I had tried numerous devices and this belt is the best, I have a couple of different configurations which helps as because if I am getting uncomfortable with one crotch module I can switch to the other module. The main module I use it a Fun style with cable and the other is a shield style with a rear opening instead of a cable. Both are very comfortable but do feel quite different.
It did take a long time to adapt to regularly wearing a belt, months even and if I stop wearing more than a week I have problems. Typically some re-adapting period is needed so it is important that I don't take long breaks or I won't be able to leave it on during times when I really need it. Of course as I go back to wearing 24/7 (something I have done in the past) this should hopefully be alleviated.
I am definitely against the idea of anyone wearing a belt involuntarily, so I feel bad for those here where it seems they are more or less coerced to wear.
Hope that all makes sense.
