Can I mess in a huge diaper?
Why would you want to mess in a huge diaper?
It feels good.. I am able to get good sleep..
You shouldn't really be wearing diapers if you're an adult unless you have some sort of incontinence issue. It would be strange to be making a mess in your diaper just so that you can sleep.
Oops, Oh I need to mention that I'm a trans girl too.
I am not sure what being trans has to do with wearing a diaper but adults don't wear diapers unless they need to for a medical reason.
