My bladder headcanon for the mane 6 · 8:00pm Sep 24th, 2016
(UPDATED AS OF 8/20/17)
This where I'll be posting and updating my current bladder headcanon for the mane 6. This is what my stories will be based off of (Unless otherwise noted) so while it's not required you actually read all of this stuff, you still can if you're interested. (If it's your fetish anyway then why wouldn't you be interested?) I also have reference images for what the characters are supposed to look like (Pony, anthro, and humanized) I can't link NSFW images directly to this blog though, but I can give you the reference number of the image from Derpibooru. ^^
If this isn't clear already, this is fetish stuff .3.
I'm also adding something new that elaborates on how skilled the ponies are at actually holding it. Just because they have the capability of being able to hold it for a really long time doesn't mean everything. For example, if the ponies are affected by any outside factors, this will dictate how well they'll be able to hold it through these instances. This will be done through a number system of 1 to 5. So:
1 = the worst at holding it when dealing with outside factors
3 = average
5 = best possible
If this is still confusing though then let me put it this way using Rainbow Dash and Twilight Sparkle as an example. Both of them have extremely similar lengths of time of how long they can hold it. However, let's say that after about three and a half days of both of them holding it, they get frightened by something. Rainbow Dash is really good at maintaining a secure hold on her bladder-- she's ranked as 5-- so she manages to hold it before anything leaks out. Twilight, however, only has 3, so she accidentally pees herself for a few seconds before realizing what's happening and regaining control. They both can hold it for about equally as long, but as seen here, Rainbow is more capable of holding it through certain circumstances. These circumstances can include: Being frightened, any type of physical activity, stressful situations, etc-- basically any type of outside factor. So in a way, this number pretty much dictates how much willpower they have to keep holding it.
This number can be affected by other things too such as:
-Moral support
-Love
-Competition (for someone who's super into that like Rainbow)
You get the idea.
TWILIGHT SPARKLE:--------3
Twilight Sparkle (Non-alicorn) can hold in her pee for a maximum of just barely 4 entire days (96 whole hours) although reaching the four day mark to her is incredibly difficult, so she may not always reach it depending on how much liquids she's had, what she's doing, or any other outside factors. This is more like a maximum possible time and it's not expected for her to actually reach that long without other factors being in play. Similar to Rainbow Dash, she can press the outer-lips of her puffy marehood together as a secondary way of keeping her bladder full. She actually has more control of them than Rainbow Dash does, and therefore can hold it in that way for a few minutes longer.

RAINBOW DASH:--------5
In the story that I currently have uploaded (Rainbow Dash's pee desperation), you'll see that Rainbow currently has a goal of wanting to hold it for four entire days. Her and Twilight are actually very similar when it comes to how long they can hold it and how they can hold it. They're the only two characters that can hold it in with the outer-lips of their marehood, and Rainbow is more openly determined about holding it.
Her reference image is #341631 on Derpibooru. (Anthro. Some similar ones include: #1510521 , #1488649 , #1473410 , #1140568 , and #971451)
PINKIE PIE:--------2
Pinkie Pie can manage to hold it in for around 30 hours at the most on average. One thing I could mention with Pinkie is that when she gets really desperate, she gets really super fidgety and squirmy (With her pony version being more exaggerated than anthro/humanized) and that fits her hyper personality.
Her reference image is #723794 (Humanized)
#1003155 (Anthro)
#1407922 (Pony)
APPLEJACK:--------5
Applejack can hold it for up to three days if she puts the time away into focusing on that. Because she's working on the farm alot though, and she's drinking alot of water so it's going through her system fast due to the physical activity, she'll usually just last sometime in the two-day mark. I also like to think that her bladder is very thick unlike everyone else's, which would give it more room to expand if it's necessary.
I also have a futa headcanon for Applejack too: Her penis is very strong, and because of it, she can hold in her pee for up to five entire days. One thing that she can do is squeeze her penis with her hoof when she loses control, which can prevent herself from actually peeing. She could then go pee wherever or whenever she wants .3.

#374947 (Anthro. Same as the previous one but it's just not futa)
FLUTTERSHY:--------1
Fluttershy is currently a bit all over the place for me right now because I have multiple stories written about her. In one story she has an overstretched bladder, which I've considered for that to be my headcanon but I still haven't decided if that's something she'll already have or if that's something she'll actually get overtime due to certain... things happening in the story .3. With a completely normal bladder, she can hold it for around two days on average. When it's overstretched though, she can reach up to three-four days, and maybe even further because of the symptoms of an overstretched bladder. Like for example, not feeling that much of an urge even though her bladder is full.
Her reference image is #210820 , #211816 (Anthro. I've also used #313539 though)
#977037 (Humanized)
RARITY:--------2
Rarity's time depends on when she pees. She can hold it for the least amount of time out of the mane 6, which tops at the 24 hour mark. In order for her to reach that long though, she has to pee at around 12 in the afternoon; she would then go to sleep the following evening, wake up absolutely bursting, and through pure determination and willpower be able to reach the 24 hour mark. If she were to pee too early in the morning, she'd be too desperate to get to sleep, and if she peed to late into the afternoon, she'd never be able to make it that long throughout the next day. I'd say a good average time for her is 12-16 hours, but again, it depends on when she pees and when she sleeps.

Quick 4/23/18 update, in which I'm going to clarify the following:
The times here are extremely long compared to average ponies, and part of that is because these are their maximum possible times. They can reach this far if they're fortunate enough to have convenient outside factors that make it easier for them to hold it (Like being able to lay down and not having to do anything) So for example, if Twilight is only on her second day, she might still pee herself if she's outside walking and being busy all day long without ever getting a chance to rest and regain her composure. She can also be desperate to pee as early as 12-24 hours in, but that urge can go away overtime because that's kind of how it works naturally. It really just depends on alot of factors, and that doesn't even include liquid intake, so it offers plenty of room for flexibility during RPs and stories.
