There might be a better phrase for this idea but I'm not aware of it, so I'm just winging it. For those who avoid physics, "dark matter" is what makes up most of the mass of our universe but it is very hard to perceive directly for us. We see its effects and that's about all. What I'm thinking of in terms of this thread is how do you manage the aspects of your life that you keep private from most people and what accomodations do you make to keep them that way? Given the audience, this most likely applies to ABDL stuff but it could be anything.
In my case, my ABDL practices are pretty private, so it's relatively easy to manage. I live alone and as long as I keep things tidy, I can have people over none the wiser. The more involved effort for me has been the one I wouldn't have expected when I joined up here: it's dealing with the social aspects of being an ABDL. I have friends, both online and nearby who I interact with. I have traveled to see them and they come to see me. These people are my friends and those social connections tend to bleed over into my mundane life. Due to the right skills, my company contracted one of them briefly for some work (good results all around). Friends and family have met some of them and since I'd rather not say that they're my ABDL pals from a diaper support site, I have occasionally needed a plausible cover story. Online gaming has worked wonders for me in this area.
My biggest hurdle at one time was coming back to work on Monday having gone to a meet or just had a slack weekend with a lot of diapery stuff and having little to talk about. Now it could be a visit from a friend of days or weeks. I know most people are caught up in their own business most of the time, so it's likely not that much of an issue. Still, I wonder how it is perceived by those who think about it.
