To me the worst part of not wearing a diaper is when you wet your pants in public that is very embarrassing so that is one. The other is to wet the bed at night and to wake up to that is not fun and is a lot of work. I find it very comforting and secure to wear a diaper and use for its purpose.
If I'm sleeping without a diaper that means something is horribly wrong and the bed is not going to be s happy camper in the morning.
I have frequent urge incontinence. Wearing a diaper enables me to do all the various things that I need to do during the day without worrying about having visibly wet pants. Wearing at night helps me sleep better and protects the bed.
Luckily I was wearing my diaper just now as I needed to get the garbage out to be collected! I got the garbage out just in time for the garbage truck, I would have wet my pants in front of the men on the truck!
If I'm not in a diaper, I get very anxious, jittery, nervous and stressed out. It's at that point where I start to worry about using the gendered bathroom that I am not comfortable in. I wear diapers and have to be in diapers, to stay relaxed, calm, stress-free and worry-free.
