Review: Holy Trainer Nub V5 Male Chastity Device
A short time ago, I reviewed the Holy Trainer Nano V5 (Link). This used to be the shortest model Holy Trainer offered. As I pointed out in my review, the Nano was too long. My penis didn’t remain in firm contact with the front of the device. That meant my urine stream didn’t flow neatly out of the front hole provided for that purpose. It made a mess.
Fortunately, Holy Trainer makes a shorter model, the Nub. This device has a shorter tube than all of their other models (see size chart above). Please note that there are two length measurements provided for each tube. The “A” measurement is the length from the top to the tip, including some of the ring. The “B” measurement is less useful. It’s the protruding part of the tube.
The Nano’s “A” measurement is 3.1 inches. My penis, at its most flaccid, is about 2.5 inches. You can see that there is a good reason I don’t touch the end most of the time. The Nub’s “A” measurement is 2.2 inches. Perfect! For years people, including me, have stressed measuring penis length at average softness. I learned through experience that my cock didn’t need a cage the same length as my soft penis. In fact, some compression turns out to be a good thing. The head needs to be in firm contact with the front of the tube to assure accurate, neat peeing.
When it first came out, many considered the Nub too confining. They were fooled by the “B” measurement and the natural male inclination to overestimate cock length. Sooner or later, even the most diehard long-cage fans had to acknowledge the benefits of a shorter, properly-fitting penis tube or cage. It turns out that the Nub is more than a chastity novelty. It’s the go-to size for a lot of us.
wearing the Nub
It was a little more difficult getting into the nub. The more compact tube left a bit more excess skin to get in the way while putting it on. I can’t complain about the effort. It was only slightly more than I needed with the Nano. Once on, the Nub was supremely comfortable. I think the bio-sourced plastic used by Holy Trainer provides a “softer” feel. The plastic is hard but feels good on my skin.
The V4 and V5 base rings are wider than earlier versions. I find that more comfortable. For guys used to narrower rings, it might take some getting used to. The Nub’s shorter tube makes it invisible, even under tight clothes or bathing suits. The penis nestles between the balls and stays out of sight.
I love the new lock. Unlike any other male chastity device, the Holy Trainer V5 models have a built-in lock. There are no parts or pieces to insert or lose. The device can be put on without a key. That makes travel and long-distance wear more secure. The device goes on, and a simple click of the lock does the job. No key is required. The lock is high-quality stainless steel.
The Nub is very lightweight. I don’t feel that I’m wearing a male chastity device. I remember it when my cock tries to get hard. The Nub makes sure that doesn’t happen.
If you are wondering about what size Holy Trainer to buy, my suggestion is to measure from your body along the top of your MOST flaccid penis. You want to measure when you come out of a cold pool. The trick is to buy a device that will hold the head of your penis against the front of the device. Don’t get carried away. If your most flaccid length is four inches, then get the size designed for that length.
A word of caution is important here. As of now, the cheap Chinese knock-off male chastity device makers can’t duplicate the Holy Trainer V5s because of the integrated locks. At some point, they might be able to do it. Stay away from them. They are made of cheap plastic and don’t fit as well as the Swiss-made Holy Trainers. Aside from the moral reason to avoid knock-offs, the imitators are not as good.
Holy Trainer ships quickly and uses an express service that gets you your device in a few days. I am very happy wearing my new Nub.
