As always, make sure bdsm/kink play is safe, sane, and consensual. Never leave your sub alone during bdsm play. Prepare everything needed before restraining your sub so there’s no need to step away until after you’ve released him. When using rope or any tightly fitting cuffs, always periodically feel your sub’s hands/feet/balls (whatever is tied) to ensure they aren’t cold. Cold is a sign of circulation loss which needs to be addressed immediately by removing the restraints in that area before your sub gets hurt.

Specific to chastity, ALWAYS make sure your sub has at least 2 to 3 ways to contact you while you have his dick locked. An emergency may be rare, but if/when it happens, you don’t want to look like an irresponsible Dom. It could turn out to be a very bad thing if your app notifications are turned off when your sub sends you a message on an app to tell you that his skin is chafed and looking pretty bad, if that’s the ONLY way he has to contact you. You can make an app message the primary method of contact if you prefer, but give him your phone number to text you and setup guidelines for such cases. For example, “If you need me and it’s a non-emergency, contact me on ABC app or send me an e-mail and I will reply with 24 hours. If it’s urgent but not an emergency that jeopardizes your health in any way, text me. If it’s an emergency that is or could jeopardize your health, call me immediately.”

Also, set you sub up to win, not lose. If he’s never been locked in chastity before, not even to try on a device, understand that the first device he tries may not work for him. Start his chastity term short and see how it goes. Be aware and cautious with devices that have potential pinch points, and monitor new chastity subs frequently for the first few days. You could require your sub send you a close-up photo twice per day, primarily for the purpose of checking for any issues that he may not have noticed (and to make sure he’s still locked, of course). ;)

1. Make sure your sub has at least 2-3 ways to contact you, and at least one way to ALWAYS reach you regardless of whether you're at work, at home, or anywhere else.
2. Agree on the term of chastity, rules, etc. For example, "One week chastity term. If the sub whines or asks to be released early, one day gets added to the chastity term each time he asks." Obviously an emergency or anything that negatively affects the sub's health overrides this.
3. Lock your sub in chastity, making sure the device fits him well and doesn't pinch.
4. You should always try to reserve some time to spend with your sub after he's locked, to ensure he can move around without the device pinching him, to make sure he can use the bathroom while wearing the device, and to make sure it doesn't feel horrible after an hour or two of being locked.

CB-6000

This device is great for subs that are new to chastity. Many subs use this device to try out chastity and get comfortable with the idea of being locked. Depending on where you buy it, it normally includes several different sized rings to go around the dick and balls, spacers of various lengths, a padlock, and several numbered plastic padlock tags to allow a sub to release himself with the Dom knowing he did so.

Sizing of original device:

3 1/4" length 1 3/8" inside diameter of cage

5 ring sizes - 1 1/2", 1 5/8", 1 3/4", 1 7/8", 2" inside diameter

Pros:

Very adjustable for different sized subs with all of the parts that are typically included with this device.

You can find plenty of knock-offs similar to this device which can be a pretty inexpensive way to try chastity. Just be careful, as many knock-offs will split much more easily. I wouldn't recommend a cheap imitation for long term chastity. I would only recommend it to get used to the idea, understanding you may be spending $20 instead of $150, but you may also be wasting $20 on a device that cracks open in a week or so.

Cons:

With so many parts, there tends to be just as many potential pinch points.

This device has a tendencey to split right down the middle with a lot of pressure (just because your sub is locked doesn't mean he won't get hard).

Very low security. Escape is as easy as grabbing a pair of scissors and cutting a plastic pin behind the padlock.

CB-6000s

This device is the same as the CB-6000, but the cage length is shorter.

Sizing of original device:

2 1/2" length 1 3/8" inside diameter of cage

5 ring sizes - 1 1/2", 1 5/8", 1 3/4", 1 7/8", 2" inside diameter

Plastic knock-off chastity device (unknown name)

This device was given to me by a sub. Despite my efforts to identify it, I wasn't able to find a name for it. However, I wouldn't personally recommend this device anyway for a few reasons, so I'm including it here as more of a warning for things to be aware of.

Pros:

May be a good device, if obtained inexpensively, to get a feel for chastity and see if it's for you.

Cons:

A lot of pinch points due to the design of this device. The two halves (upper and lower parts of the cage) touch together all around the edges. This makes for a very large potential pinching area. Also, there are several plastic rings that are somehow used as spacers (I'm still not sure I was able to piece it together properly since no matter what I tried, it didn't make much sense to me). In any case, the more parts that are pushed together, the more potential pinch points.

Two padlocks. On some devices this could be viewed as extra security, especially if it only required one lock to keep your sub's dick locked, and you use two padlocks with different keys. However, on this device, I see no simple way of securing the padlocks down so they don't jingle. This makes for a chastity device that's more noisy and obvious to people when you're trying to keep it private.

No "air holes". Most devices have slots in the cage for breathing points, which also help for cleaning as water can flow through them. This device is pretty solid plastic without many areas for soap and water to enter in the shower (just a hole for the balls to fit through, and a small hole to piss through).

Holy Trainer V2

The Holy Trainer V2 is a great device, in my opinion. It's pretty comfortable for most subs, and it's made of a resin material that actually molds to the sub's body over time, making it even more comfortable than it is to begin with. The molding to the sub happens in a hot shower or bathtub as the device heats up. Also, I've read several reports (including on the Holy Trainer web site) of this device getting through airport security without setting the detectors off, which is another perk for long term chastity.

Sizing of original device:

(with this device, you must specify sizing when you place your order)

Standard: 60mm (2.35") length, 35mm (1.4") inside diameter

Small: 48mm (1.9") length, 34mm (1.3") inside diameter

4 ring sizes – 36mm (1.41"), 40mm (1.55"), 45mm (1.75"), 50mm (1.95")

Pros:

Comfortable, and molds to the sub's body.

Good security overall. Although I don't consider most non-steel chastity devices to be high security, this device is different. Between of the fact that the device has no flimsy plastic pins that can be cut, it's pretty solid without being likely to crack or split down the middle. The built-in lock means escape isn't as easy as cutting through a padlock with bolt cutters when your sub is incredibly horny.

Available in a few different sizes.

Only two pieces which are strategically placed and greatly minimizes the chance of pinching.

Cons:

A bit more expensive than some devices, but you get what you pay for.

Electro Lockdown E-stim Chastity Cage

If you want to lock your sub in chastity and stimulate his dick using e-stim, this is the cage for you. I wouldn't recommend this cage for long term wear, but it's great for a session with the intent of unlocking the sub before he heads home.

Sizing of original device:

82mm length 34-47 mm inside diameter cage (at smallest and widest points)

Adjustable ring

Pros:

Adjustable ring and multiple spacers are included, which allows for many sizes.

E-stim pins (cable included) attach to the sides of the cage to allow you to stimulate your sub's dick after locking it up.

Cons:

Many parts, which means many potential pinch points. Since I wouldn't recommend this cage for long term wear, I don't see this as much of an issue. Just be careful during play and try to avoid pinching, and with the e-stim feature, your sub will have a lot more to focus on anyway.

This device is plastic with some thinner parts, so it's pretty easy to cut (low security). But again, if only used during a session, security isn't an issue since you'll probably have your sub restrained anyway. ;)

Jail House

The Jail House is a very solid device which most subs find to be pretty comfortable. There are only two pieces, which minimizes potential pinch points. It doesn't swivel or move much once locked, which also adds to its comfort.

Sizing of original device:

3.25" length, 1.5" inside diameter of cage, 4.5" circumference

3 ring sizes – 1.5", 1.75", 2" inside diameter

Pros:

Very solid, not much movement when locked.

Two pieces which minimizes pinch points, and the solid ring helps as well since there is no hinge and no extra pieces sliding together.

Cons:

Uses a solid ring around the sub's dick and balls. This may be difficult to get on some subs, or frustrating for the Dom if one ball slips back through the ring before getting both balls and dick through the ring.

Bird Cage

The Bird Cage is a device I haven't used often, since I prefer a few others.  However, it's a great go-to device for subs with larger dicks, and it's less expensive than many steel devices.

Sizing of original device:

6" length (but it curved downward), 5.5" circumference

Ring size – 2" inside diameter

Pros:

Steel device without the typical high cost.

Only two pieces which minimizes pinch points.

Cons:

Solid ring, which is sometimes more difficult to get your sub's dick and balls through.

Large ring and cage, which is typically only suitable for more hung subs.

May show under the sub's clothes more easily than smaller cages.

Master Series Extreme Urethral Chastity Cage

This a nice, high security cage, made of brushed stainless steel. It's heavier than most other chastity devices,  so some subs might not like that. On the other hand, it's a constant reminder that you own your sub's cock. ;)

Sizing of original device:

4.25" length, 1.5" width of cage, 5" circumference

4 ring sizes – 1.5", 1.75", 1.85", 2" inside diameter

The urethral insert is 2.75" in length

Pros:

Highly secure device which uses a proprietary bit and tool for locking/unlocking.

Optional urethral insert (you can easily add or remove it from the device), for even higher security.  (removed in photos below)

Weight (if you prefer a heavier device).

Cons:

Rings are hinged, which normally add pinch points (but does make it easier to put the device on). However, this device includes rubber coverings around the hinges. I recommend sliding the rubber over a bit more so it covers both sides of the hinge to prevent pinching.

Weight (if you prefer a lighter device).

Larger than usual gap between cage and ring which means more chance of pulling dick out.

Mature Metal Jail Bird

This is a very nice custom device. It's pricey, so you probably won't want to start with this device since you may have no clue what size you need, and around $340+ is a lot to pay for a device you may get no use out of. But once you know that chastity is for you (or your sub) and you know the perfect size, this device is great.

Sizing is custom from a wide variety of options. You can customize the cage length, the cage diameter, the ring size and shape, and even add options for added security.

Pros:

Nice, solid device.

Custom made to the sizing the sub requests.

Highly secure device, if you order it that way. You can order it with a security screw and anti-pullout pins, for an extra cost.

Cons:

This device starts at $340.00 (at the time of this posting). Options such as extra rings in the cage, security screw, and anti-pullout pins can quickly add to the price.  For example, 3 punishment pins, a security screw, and no other options added brings the price tag up to $485.00. I'd still say it's worth the cost if you have tested chastity with other devices are decide that you're in it for the long haul. Otherwise, this device may break the bank for a short term "toy".

Full Chastity Belts

There are several of these belts out there, and many knock-offs. These belts offer a lot of extra security and control over your sub. The downside of most regular chastity cages out there is that preventing your sub from pulling his dick out the back of the cage is virtually impossible. You can make it challenging with things like Mature Metal punishment pins, and/or difficult to get his dick back in the cage so you may find out about the pull out. However, there's no really good way to prevent it entirely. Except...with a full chastity belt! (For long term chastity in one of these, just make sure your sub is able to use the bathroom without too much trouble.)

Sizing varies from one device to another, but most of these belts will accomodate a small range of waist sizes with a single belt.

Pros:

Higher security than most cages.

Preventspull outs if the device is fitted properly.

Cons:

Full chastity belts are typically pretty expensive.

Hygiene can be more difficult since full belts usually don't have much of an open design (open slots that you'd find in most cages).

You'll need to check up on your sub more often. If he has chaffing on his skin or anything similar, he may never know it until you unlock him to check.

Homemade Velcro Chastity Device

This one is great during a play session, but not designed for long term chastity. Part of the reason for that is because it doesn't lock on the sub, of course. But it's great for use in the playroom when your sub is restrained and you're stimulating his dick, watching it grow into the prickly velcro. To see how to make this device, see this post.

Pros:

Very inexpensive (making this device can cost as little as a few dollars, or free if you already have some self-stick velcro at home).

Very easy to put on your sub's dick. No rings to fit his dick and balls through, and no pinch points to be concerned about (other than the obvious prickly intentions of this one). ;)

Cons:

Not lockable.

Not designed for long term chastity, or the long term control aspects of chastity.

A few additional tips and ideas:

If you already have a chastity cage and just want to spice it up a bit, try taking two small squares (or thin strips, or thicker strips, it's up to you and how rough you and/or your sub want it) of the rough side of velcro and sticking them inside a chastity cage. See more details in this post.

If your sub is uncut, you can still lock his dick in chastity, but you'll need to be careful and aware of a few things. Hygiene will be more difficult for him, which typically requires regular unlockings for more thorough cleanings. A good rule for most is at least once per week, but you and your sub will have to judge as everyone is different.

Also, if your sub is uncut, this may make it more difficult to get his dick in a chastity device, especially if he's more sensitive. However, a friend of mine came up with a great way to make this incredibly easy, and he uses it himself. Thanks to @hushpuppy1980 for taking a quick video today for me, just so all of you could see how easy this can be. (Due to the way videos like this work on Tumblr, I had to turn parts of the video into an animation.)

Just take a tissue, put it under your uncut dick, fold one side over, then fold the other side over. Next, twist the end of the tissue until that end becomes much thinner and will fit through the hole at the end of the chastity cage. Push the tissue through your cage from the back, then slowly and carefully pull it out through the hole at the end as you pull the cage over your dick. Just be sure to get all of the tissue out before locking the cage on. If the tissue rips, start over and try it again with another tissue.

Next week: Take a few items you may already have in your garage/basement and workout area, and turn them into a disappearing bondage table. When you're playing, you see it. When you're done, it looks like a few ordinary household items.
