Guest Review: CB-6000 Chastity Cage

My partner and I have been getting into chastity play over the past couple months. As one of their assignments for me, I recently asked them to write a guest review of their first cock cage. Here’s what they had to say!


I’ve long lusted after the CB-6000 from CB-X. It’s the latest iteration of the most popular chastity cage for penises on the market; you see it in chastity porn, posts on Reddit, and hanging on the wall of just about every sex shop you walk into. When it was on sale online recently for $100 USD, I asked Kate if I should order one, and she seemed almost as curious about what playing with “enforced chastity” in our dynamic would be like as I was. So I decided to pick one up. But first, I had to make two more choices: size and color.

CB-X makes their cages in 3 sizes: standard (6000), small (6000-S), and large (“The Curve”). Be careful when measuring your flaccid penis to decide on a size, because if the idea of locking up your cock appeals to you enough to buy one, you’ll probably get a little worked up like I did and accidentally order up a size. If you do, you can always purchase just the cage portion in the future for less than the cost of the entire set.

Prevailing wisdom suggests that almost everyone should order the 6000-S. It’s the best-selling size, and it fits many flaccid cocks – even if, just looking at it, you might think it won’t. In a cock cage like the CB models, you want a tight fit to make urination easier and to suppress and contain erections more effectively.

The cages also come in a variety of colors and finishes: classic clear, pink (especially popular among kinksters into sissification and feminization), red, polished chrome, gold, wood (?!), and (most bizarre of all) camouflage. I chose clear because there’s something even more erotic to me about the idea that I can “look, but not touch.” It also seems prudent to get a clear cage if you’re trying chastity for the first time and want to be sure you’re cleaning and drying your cage properly and avoiding any potential penile injuries.

The CB-6000 arrives in a black zip-up carrying case containing the polycarbonate cage, 2 bases, 5 U-rings, and 4 locking pins and spacers to control the width of the gap between the ring and the cage where your balls hang down. The kit also includes a brass Master lock (not that kind of Master), two keys (one for emergencies and one for your keyholder), 5 numbered plastic locks so you can wear it through a TSA screening, and a sample of silicone-based lube, which helps to get the cage on correctly and keep it from chafing day-to day. To use the tamper-evident travel locks: put one on, send a verification photo to your keyholder if they’d like one, toss your unlocked brass lock in your luggage, and go through security as normal. Once you’re through, you can switch back to the real lock and re-verify in the airport bathroom or your destination.

Unboxing and figuring out how to put on this device is… a process. With everything spread out on my bed, I watched this YouTube video from the company and thought I had the hang of it. The first step involves selecting the right ring size to fit around your cock and balls. You want something snug but not constricting, so you should be able to fit about one finger between it and your scrotum. Then you lube up the head of your cock (or use something called the stocking method) to slide into the cage. The problem, again, is rubbing lube all over your dick and thinking about chastity very well might make you hard, and the cage won’t be able to close correctly when you have an erection. So you’ll need to wait until you can keep your arousal under control for just long enough to slide a locking pin and spacer through the base and secure the lock. Getting the cage on is also much easier if you’re clean-shaven, but even if you are, there are still lots of spots where it can pinch your sensitive skin if you’re not extremely careful.

I initially wore it with the second-largest ring and largest spacer, but I quickly realized how important sizing is and adjusted to smaller sizes. If you pick too large a ring, the cage will slide down your shaft and be too easy to slip out of; too tight and you’ll constrict blood flow to your balls and they’ll end up feeling cold and turning purple (fine for a few minutes, not safe if it persists). After a few days of experimentation, most people will be able to find a combination that works for them. This ability to customize the size of the ring and gap is one of the best things about the CB series of cages and why I picked it as my foray into this kink. Rather than spending $300-$500 on a custom-manufactured steel cage, you can use this kit to figure out exactly how you want chastity to fit into your life – and onto your cock – before dropping that kind of dough.

The CB-6000 is a classic for a reason: it’s incredibly good at what it’s designed to do. It’s very difficult (but not impossible) to escape from if worn correctly, it makes touching your penis for the purpose of pleasure impractical via hard plastic and small slits that most fingers can’t penetrate, and it’s nearly undetectable under clothes, even my tightest jeans. Plus, it allows for easy cleaning and urination. While you can wash with a showerhead or under a bath faucet, I opted for a squirt bottle with an angled tip, and while some users can pee standing up while wearing it, I nearly always sit down and wipe after to avoid making a mess.

But it’s not without its flaws: there are two major downsides to this cage. First, it’s very difficult to sleep in, compared to other cages on the market. The circular shape of the ring causes tight compression of the scrotum during nocturnal erections which will wake you up a few times a night feeling like you’re getting (gently) kicked in the balls and stumbling out of bed to pee and walk off the pain. Second, there are tiny vents on the side of the cage that cause unsightly bulging when you get hard in this device, with thin strips of sensitive skin poking through the holes whenever your cock fills the cage. The latter is mostly an aesthetic issue for me, and some wearers tape over the holes to avoid this. But, those vents can also leave visible imprints on your shaft when you take the cage off that can last an hour or so at the very moment when you probably want to show off your cock to a partner who has just unlocked you. Not ideal unless you’re into seeing yourself pinched by plastic in a masochistic or CBT way.

Wearing the CB-6000 for 9 days straight last month was one of my favorite kinky things I’ve done all year, leaving me hypersensitive, attentive to my partner, and leading to an orgasm after I was unlocked that felt 5 times stronger than usual. Despite its flaws, it’s clear why it’s so many people’s introduction to chastity play. It’s the only sex toy I’ve ever purchased that’s guaranteed me fewer orgasms, and I’m certainly not complaining… or if I am, it’s all consensual.
