Modifying your security settings: The CB3000 & 6000

As you can tell from the title, this is going to be one of the more technically oriented posts, so if you aren’t interested in the geekier aspects of chastity devices, then I suggest that you toddle off to look at my HNTs.

The CB-2ooo has been around since the mid to late 1990s; the 2k was not the first inexpensive male chastity device, but it soon became one of the first widely marketed, mass-produced models. The original versions were built from machined and glued acrylic pieces, but as the demand grew, AL Enterprises invested the money to have the sections molded of polycarbonate plastic. Easy to clean, and not too finicky to modify, the 2k went from a novelty to a full time business.

The success of the 2k allowed AL Enterprises to invest money in a more complex design: The Curve. While it did not gain the wide following of the previous version, it paved the way for an even more complex design in the CB3000. The 3k, perhaps because of the outside shape, took the “trapped ball” style devices out of the “adult novelty” section and into a variety of other categories. Over the last few years, I’ve seen references to the 3k pop up on a wide range of websites. Yes, most of them are of the “WTF is this for?” genre, but just the fact that other people comment on those items shows that they are becoming, if not more popular, at least not so unusual.

Last year’s introduction of the CB6000 was more evolutionary than revolutionary, but the trimmed, sleeker shape seems to be at least as popular than the previous model. Personally, I’m disappointed that the new model isn’t made to be interchangeable on the cuff rings with the previous versions, but anyone with some tools and a bit of creativity can figure out how to work something out. After having worn both devices for some length of time, I find that I prefer the 3k, but it’s a close call.

The success of the CBx000 line can be shown by the various group discussions, the large number of hints and tips about wearing the devices available around the web, and in number of after-market add-ons that have sprung up over the last few years. It speaks volumes, however, that the most popular discussions (and most common add-ons) have to do with enhancing either the comfort or the security of the devices.

Some users of the original 2k noted that with some lube and a few minutes, they could wriggle their penis out the back of the cuff ring. The device would still be attached to their bodies, held on by the thin space between the cuff ring and the cage (hence the moniker “trapped ball” device), it became clear that the device, while preventing intercourse, could still allow one to masturbate. While this isn’t a concern with some people – chastity being, of course, about fidelity within a relationship – those interested in exploring orgasm control, either with regard to a personal sacrifice, or in a BDSM context, have been disappointed. The 3k and 6k, unfortunately, haven’t seen many improvements in that regard, at least, not if the reports of the various web boards and email lists are any indication. While the devices have improved in comfort and wearability, a lot still depends upon the personal anatomy of the wearer.

CB6000 Mods

This problem is not limited to the CBx000 line, by any means; I’ve seen users of various other devices with similar complaints. Some men who are able to pull out of one device report it to be impossible in others. Some other men report that they can pull out of all of them. The problem stems from the fact that some men can compress their squashy bits more than others. The 3k, though, seems to have more options for security than the other devices by AL Enterprise, and the various other devices manufactured – especially the ones made from stainless steel – don’t really have any. If you can pull out of device, unless you have a genital piercing, preferably a PA (Prince Albert), then for the most part your device is more symbolic than actual.

Security Mods

I’ve mentioned elsewhere that I have needed to modify both the CB3000 and the CB6000, both with some degree of success. A while back, I had the idea that I could anchor myself in the 6k with an O-ring attached to an elastic (which would provide some slack to accommodate the natural movement during the course of the day). It worked really well – for about three days, when, while cleaning the inside with a cotton swab, I discovered that I could ease the O-ring off, and later, ease back into it. So much for my simple idea.

Fortunately, there are more practical security add-ons for the CBxxxx line of devices. The most well known are probably those sold at www.keptforher.com, and are known as the KSD, or “Keepsake Device” line. The G2 is essentially a molded plastic reducing bushing; it slips into the inside of the CB2000 or CB3000, and provides a smaller opening – the idea being that once squished into it, it would be very difficult to wriggle out of the back. This seems to work for a lot of men, although there are some issues reported. The snug fit can sometimes be too snug for those men who are “growers,” causing the blood to be trapped in the penis, making it swollen or difficult to remove. But the biggest issue is that some men are simply too flexible and squishy to be anchored by such devices.

The next design by the Keptforher folks is actually a complete change on the “make it snugger” school of design that we tend to see for chastity device add-ons. Thinking “outside the tube”, they have a plastic insert that looks like the top half of a bushing , with a tongue extending an inch or so into the tube. While designed with the 6k in mind, on a 3k it would cover the top vent holes (which pretty much serve no other purpose than to allow you to swell up through them like little skin balloons).

The tongue tapers a little bit, with the end terminating in a small flange that nestles in the ridge behind the head of your penis. The flange does two things: it helps to keep your penis in pretty much the same position inside the tube during the course of the day, and while there are no sharp edges, it does create a blockage for the loose skin, should you be tempted to try to pull your penis backwards. It’s quite simple, and when you see it working it makes you wonder why nobody had thought of it sooner.

Over the last – wow, has it been ten years? – that we’ve been experimenting with chastity and OD at the Edge of Vanilla Labs, there has always been a tug of war between the comfort and convenience, and the security of the several devices that we’ve tried. The ability for a lot of men to pull out the back is, I think, one of the reasons that the AL/CBxxxx devices are often considered to be “toys” or not worthy of serious consideration. I think that the latest G3 might work well enough for the majority of users to satisfy both the comfort and security concerns. I wore a G3 in my slightly modified 3k for about six weeks straight, and did not have any problems with fit or function.

Why such a long post on this? First, to provide a little background, because – believe it or not – chastity devices are still a pretty new fetish, and based on the conversations that I see in the various groups, people seem to be discovering them every week. However, I also wanted to lay out some technical groundwork before I started my review of a similar device, because that will take an entire post in itself.
