Could we compare everyone's idea of proper CD fitment?

I've never had a CD but I'd like to compare everyone's different opinions of fitment based on the measurements I have taken of myself, I'm thinking that this could be quite interesting to see how different all the measurements will be for your idea of the "Right" size, I'm also, of course, hoping this will help me when it comes time to get my MM Jail Bird (I currently have a cheap A080 from DH Gate on order to also aid in the proper sizing for a Jail Bird). so, lets get on with it then...

Things to keep in mind...

1. I'm brand new to CD.

2. I'm considerably high & tight in all but very warm weather (which is not often where I live).

3. One testicle is about 50% larger than the other and both I believe are more sensitive than the average guy.

4. No piercings, prefer long term comfort over high security against escaping (I won't ever try to escape without permission so its a moot point.... but of course I don't want the CD to fall off either).

5. I sit all day but I also live a very active life, 5-6 months of which are in below 0'F temperatures (Canada).

6. I am uncircumcised with a long foreskin (1/2'' - 3/4'' when flaccid)


My Measurements were taken multiple times at room temperature, they are as follows:

Typical Length Measurement Flaccid (using MM method under penis): 3'' + .5'' foreskin
Shortest Length Measurement Flaccid (using MM method under penis): 2.5'' + 3/4'' foreskin
Erect length: 6.5'' measured on top, 5.5'' measured underneath.

Girth Flaccid: 1-1/4'' ring needs turning and tugging to get to back of penis, gets very tight under a partial erection. 1-1/2'' ring has roughly a 1/8'' gap all the way around when flaccid.

Base Ring: 2'' round ring (just ring, no device) is very comfortable all the time even under full erection, when totally flaccid it is possible to pull straight off with the right angle and pulling medium-hard. 1-15/16'' round ring (no device) causes some discomfort and needs adjusted a couple times an hour.


So using my information and measurements AND your experience and knowledge, what size would YOU order a MM Jail Bird in?

Ring Size? (oval or round?)
Gap?
Cage Length?
Cage Diameter?

I would send them to MM and have them tell you what you should order.

The biggest issue is here is if you are new to wearing a chastity device then I would start with a beginner device before you order an expensive custom cage. The reason is simple—you will adjust to chastity and become more comfortable with smaller rings and spacers as you go. A device that's too long in the cage or too big in the base ring will not be comfortable. Believe it or not, smaller is usually more comfortable, especially when it comes to the cage portion of the device.

Thanks for the reply! I have actually sent my measurements to MM and they have given me a guideline to follow but they did seem reluctant to actually say this is what length, gap, diameter, ring size, to order as I assume they don't want to tell me exactly what to order in case it's wrong, which I respect. As I mentioned in my first post I have a cheap device on order (not here yet) to help determine what size to order and I do understand theoretically how it is "supposed" to fit (and that shorter is better) but what I was hoping to do is discover how different everyone's opinion of the "proper" fit is. I expect there will be some difference of opinion and I was hoping to see how similar/dissimilar everyone's sizing opinion will be based on my static set of measurements for an "apples to apples" comparison.

[Edgewood]

My idea of proper fit is where the feeling of the device almost disappears but not quite. And to me the key is getting the base ring right. I think that there's a range of tube lengths that will work for most people but if you get the base ring wrong by 1/8'' or a couple of millimeters you'll really know it.

I stuff myself into a CB6000s because I'm concerned about the profile in my pants. I can do that because I'm frequently let out so I can ride a bike 3-4 days a week. The longest single stretch I might go without release is 4 or 5 days. Because of that I can "suffer" the smaller cage but to be honest I like the feeling of things being packed in. When I upgrade to a custom device I'll be going even smaller and that way my kept state will be completely stealth.

Unless you have the money to spend I would wear the starter device for at least 3 months before making a determination on ring size. It took me 4 months to get down a ring size and down to the smallest spacer.

Great, thanks for the response. I am planning to wear the cheap device I have for 2-3 months to make sure I have my sizing correct. Your last comment on ring size already makes total sense to me as I bought a couple of stainless rings from Home Depot and Rona, the home depot ring measures exactly 2'' ID when measured with a caliper and the Rona ring measures a hair (about 1/64'') under 1-15/16'' ID. I tired wearing the smaller ring first and it was very uncomfortable and needed constant adjustment I even woke up at night and it just felt too tight, so I put on the 2'' ring and wore it day and night for about 6 days and it was comfortable all the time. Last night I put the smaller ring back on and though it is noticeably tighter it hasn't bothered me really at all in the last 24 hours, what a difference from before! I'm thinking at this point anyway that a 1-7/8'' ring may be just perfect after I get used to this ring, and with the struggle it is to get this one on I'm thinking it may be the smallest that fits.

Further to what was said already, based on my experience, I highly recommend trying an adjustable device, such as a CB-xxxx device. The CB-6000s was my first device, and I was glad to have a selection of sizes of base rings and spacings. I found that, as I got used to wearing the device, I was able (or rather had to) switch sizes of base rings, and after I had worn the 6000s for a few months, I felt confident enough to order a MM Queens Keep.
Oh, and a "shout-out" to a fellow Canuck!

[little husband]

Not just a Canuck an Albertan as well!! I am defiantly still considering the 6000s if the cheap metal device we have on order from DH Gate doesn't help me with my measurements. The only thing i'm worried about with the 6000s is that i am un cut and having my skin hang through the end hole all day doesn't sound pleasant plus getting it on with a lot of loose skin and decent girth sounds like it could be time consuming and make it really hard to make adjustments during the day.

[Edgewood]

My girth is squeezed in the 6000s but it's really not a big deal. A non-waterbased lubricant will be your best friend in the plastic cage. I can go about 12 hours without having to reapply and my head can travel back and forth in the tube as needed.

As far as your skin poking out through the end, the best thing I can recommend is a pair of tight fitting briefs. They keep everything in the right place and there will be no material that can get dragged across the opening.

It's just my opinion but I think the plastic devices are better than beginner (non-custom) metal devices just because there are adjustable fitting options.

Start out with a cheap'n'cheerful plastic CBx, it will give you the opportunity to vary both the size of the base ring and (crucially) the gap between the base ring and the cage.

Someone observed that even an 1/8" (the sizing is all in 1/8" increments, nothing smaller) can make a big difference. I agree, in particular with the base ring and the gap. The length of the cage is not so important, especially as you are both uncut and a 'grower' (me too).

There is much talk about shoving fingers to the first knuckle under the base ring to assess fit, but I never got the hang of it... it's all rather squishy down there and so I played about with options until it felt right. The thing I found with the CB is that being plastic, there is a fair amount of play with the gap between the cage and ring. Try assembling it before you put it on and see how much play there is. It is this movement that caused me occasional and considerable discomfort as the smaller of my slippery friends popped out thereby allowing the other to follow. Whilst the gap can get larger, it can get smaller too. I've not found that wearing tight underwear helps at all. Probably just me, but I found going commando worked better.

If as and when you graduate to a metal CD, consider this. I invested in a MM QK. Despite having modifications and it criss-crossing the Atlantic, I still had escapes. I am not a fan of tight base rings - they block the flow of blood when an erection is building up, the dammed blood pushes the whole lot forward with some force which then throttles the testes. I consider the ring/cage gap to be more important. I happened to have bought a set of plastic sizing rings from MM, and wondered about putting a plastic ring, the same size or 1/8" smaller than the metal ring, on before the metal ring. Being loose it doesn't sit at the same place as the metal ring and it really does act like a backup barrier that has proved to be 100% effective in preventing all escapes. This works for me, you may have a different experience. The bonus is that it is also comfortable and being plastic it's light.

Good luck with your project.

I too have one testicle noticeably larger than the other. For this reason I decided to try the CB6000s due to its various rings and spacers. I though I had a good fit but my smaller testicle would slip out during physical activities and even when sleeping and twisting and turning around. Once the small one was out, the big one would usually come out too but not all the time. By experimenting over a few weeks I discovered that none of the spacer/ring combinations worked for me. I then tried something which was to put the tube flush against the ring without the spacer between them. I then put the spacer on the outside of the tube and it now does not slip off anymore. This setup also enabled me to use the largest ring which is much more comfortable.
