After reading this year-old thread: https://www.adisc.org/forum/threads/diapered-in-fursuit.114838/
I thought I'd give it a try. This was an amazing experience. For the first time ever, I got to roomshare with a diaperfur and was able to spend the entire con in diapers (from the flight to Atlanta, through the entire weekend, to the flight back home), and even wore my MegaMax diapers, with contoured boosters and terry-lined vinyl pants under my fursuit.
It was really nice to be able to drink as much Gatorade as I wanted and not worry about having to pee. Whenever I needed to go, I just let myself relax and flood my diaper. There never were any leaks and the terry lining of my vinyl pants was extra insurance that allowed me to stay in fursuit for hours on end.
I spent all of FWA weekend wonderfully soggy. I don't think I'll ever want to go without diapers at a con again, especially while fursuiting.
