The Curve Male Chastity Device

The Device
This chastity device is called 'The Curve' and it's one of a popular range of polycarbonate devices made by AL Enterprises, who craft a series of penile chastity devices. There are a number of devices in the range, from the CB-6000s (the smallest device they currently manufacture) to The Curve (the biggest) and the PA-5000 (a different style device designed for the pierced penis).
I picked this particular device because it was the biggest in the range. I'm sure this is where you all groan and think I'm just trying to brag! Seriously though, if you're thinking about buying a device, please please check measurements first. I've looked at many, many devices and the vast majority of them are small in size.

The Curve itself is made of several different parts that, when put together, form the device. The main part is the tube/cage itself. This is probably the most important part of this particular device as it's the only single part that you receive. Everything else in the pack is given to you multiple times, in many different sizes. It's just under 4" long and it's 1.5" wide. Unlike other tubes, this one is cylindrical and doesn't flatten out at any point. It's quite cage-like in appearance and has many long holes in the form of slots, all the way around, including at the end so it's sanitary when you urinate. Attached to the rear end of the tube are two, white plastic posts that help secure it when attached to one of the rings. These are at their longest when they arrive and you may well need to sand them down (as I have done), depending on the size of the spacers you find most comfortable.
The Curve comes with five rings. These range from a 1.5" wide diameter to a 2" wide diameter. They are hinged, with a metal rivet at the bottom, to make it easier to put on. At the top, there are three holes. The two on the outside for the white posts on the tube and a middle hole for an additional post (of which there are three of varying lengths). Also included are five clear spacers, five plastic single-use padlocks (each with its own serial number) and one plastic covered brass padlock with a single key (be careful not to lose this!).

Assembly
First things first. Don't rush. Fit is extremely important so relax and take your time choosing the right rings, spacers etc. before you first wear it. I find the easiest place to put it on is in the shower as you can use shower gel as lube then blast it all out when it's all fitted. The first time you try it, though, may be easier sitting down with everything laid down in front of you. The most important part of the device is the ring. This will cause you the most pain if you don't pick the right size (and leave it on too long). Start big and reduce it in size if it's too loose. Remember that what may feel good right now might feel either too tight or too loose later, depending on your arousal levels.
Once you've picked the right size ring, take one of the white plastic posts and insert it through the middle hole, which will lock the ring in place. Next take a clear plastic spacer and slip it on the white post. As with the ring, start out big and work your way down, if there's too much space. When you have the ring, post and spacer in place, just relax as much as you can as it's time to slip on the tube. There's a certain amount of irony involved with buying a chastity device for yourself. Just think about it. Being turned on by the inability to become hard or orgasm… There won't be a time when you're aware of this more than the first time you try to put your device on. It's inevitable that you'll be aroused so just relax and wait until you're soft enough to slip the tube on without issue. Trying to put it on when hard (or even semi hard) won't work and you could hurt yourself. The best time to try a device on is immediately after an orgasm (or two). It'll be much easier, but, of course, you may not want to do this. You did just buy a device to stop that very thing…
When you're finally ready (which was a good while for me), slip on the tube and line up the posts with the holes so that they lock in place. You'll then need to choose a final spacer to slip on the middle post and then lock yourself in place. I'd advise you to try out a few different size rings, posts, spacers etc. before finally picking out the best size and handing the padlock key to a loved one/keyholder/Mistress/Master/random stranger.
Personal experience

This was my first chastity device. I'd experimented with chastity / orgasm denial with my other half before, but never with a device. We'd both had fun with it before, but the device was my idea. I ordered it when she was away for a week, which wasn't intentional, but made it easier to try it on by myself to ensure I had the best fit before giving her the key…
I was extremely turned on when I first opened the package. It came in a very nice black box with ‘The Curve' in gold lettering and a gold piece of string tied around it in a bow. All the pieces came inside in little airtight plastic wallets. Probably not up to Lelo‘s standard in luxury packaging, but nevertheless a nice item to unwrap. After a few tries of different size rings etc. I came across, for me, the perfect combination. I locked myself in place and was very pleased with myself! It had been something I'd fantasized about for some time and finally I was locked!<br/> <br/>Initially, it was hard to sleep in the device, but it became easier over time. Applying a little water based lube to the ring helps to keep it moving, especially at night. It also helps to stand up or go to the bathroom if you find you're becoming too hard or if you've been woken up trying to become stiff. One thing I've also found that helps, is to change up to a bigger ring (if possible and allowed) at night. That depends on your keyholder, though, of course. In my experience, it's always good to take it off every couple of days for a good clean, anyway. Sure, you can clean it to a certain extent in the shower without removing it, but nothing beats taking it off and giving it, and yourself, a good scrub. One other thing to remember is that it's most comfortable if you haven't shaven yourself completely. This is because there is a slight risk of ingrown hairs if the device doesn't move at all. personally, I like to be 100% clean shaven so I tend to still be smooth, but I make sure I move it around a lot during the day.<br/>As far as long term wear goes, this device is fine. I usually wear it 24/7 for one or two weeks at a time (except for cleaning, of course). I've had no issues so far.

As an overall design, it's not too bad. There are some niggles, however. The rings aren't the best design. They should be flat on the inside instead of curved. The CB-6000 has rings designed in this way and I believe there is a new version of The Curve coming out with a similar design. The non-flat rings are useable, but the device can move around a bit and flatter rings prevent this from happening. It's also a pain having to sand down the two posts on the main device. If you make a mistake, you could find yourself having to order a new tube portion, although this is quite unlikely. The CB-6000 has, again, a better design as the rods come from the ring and point outwards so don't need sanding. Unfortunately though, for larger penises, this is the only polycarbonate device that will fit. If you're unsure about polycarbonate, you could try a custom metal or silicone device. I have a silicone Bon4 Plus that I'll be reviewing soon but I haven't tried metal…yet!
One other thing… It's not 100% secure. That shouldn't be a surprise though, as no device of this design is. Sure, you'll be able to find sites with guys claiming their wives or girlfriends have locked them up without their consent and they can no longer orgasm but, frankly, they're lying. With lube and persistence, you'll be able to remove yourself from the device. I'm pretty sure I could snap the white posts, too, if I ever had an emergency. Devices like this are all about the fantasy of being locked in chastity. They work, but only with a combination of device and discipline. If you're thinking of locking your partner in one of these, trust me, he'll need to want to be locked or else he'll find a way to orgasm. Only fully attached belt style devices can properly prevent touching and orgasm 100%.

Overall, this is a great device. No chastity device for this price will be perfect, but this one is close. It's comfortable, easy to clean and comes with a variety of rings & accessories for the best fit. For the larger penis, I'd certainly recommend it.
