Listing to peoples stories about wanting to wear diapers for real need 24/7, and then actually having some unfortunate happenstance befall them, reminds me of the old monkey's paw story. If you're not familiar with the story here's one link with the story http://gaslight.mtroyal.ab.ca/mnkyspaw.htm or just use Google to look it up. If you don't want to bother reading the story, the point of my bring it up is, and the moral of the Monkey's Paw story is, be careful what you whish for, you may get it.
There's a great difference in the ideal of a wish, or an idea you might have for something, then the reality of what it really means to have to live it. This applies to just about anything in life.
I too love the idea of wearing my diapers, and have many fantasies to go with them, but I can't see any fun in having something happen to ones self to justify wearing them all the time. If you want to wear and use diapers 24/7 and it makes you happy, then by all means go right ahead and enjoy the hell out of it. But don't wish for a need for them. If you need to have a pretence justification to give anybody on why you are wearing diapers, you can just make up a white lie for it.
We can see with all these fine people here who really suffer with some type of real incontinence, they love their diapers, but not being able to go without them sucks.
