I do live alone, and really, I don't have anything major. I have a bunch of diapers, but I do keep them out of site, though they are not really "hidden hidden" just more or less in a place that guests wouldn't go looking. Also, I can walk around wearing just a diaper, though I very rarely do this, though I don't do much to hide the sound as nobody else would hear it. Also, getting rid of used ones is quite simple, they go in the regular trash, no need to hide. It's nice actually.
