For me it's plastic pants and not diapers, but since wearing plastic is the key to my sexuality I'll chip in an answer here. I've lived alone since I lost my wife nine years ago. I always sleep in plastic panties and usually a plastic romper over them. My normal routine is to wear a plastic dress over whatever I slept in, do my morning web surfing, and eventually get around to showering. Depending on the day's schedule, I'm likely to wear the same dress over a t-shirt and another pair of plastic pants after I shower. If I treat myself to an orgasm, it's usually right before or soon after I shower. But it can be just about any time of the day.
