I wish my parents would have made me wear diapers when on a road trip but they didn't.
Still I wore diapers as a kid and teen when on road trips but I wore them by my own choice and had to hide the fact that I was wearing diapers on the road trip.
I always had to pee a lot when on road trips and my parents would hardly ever stop to allow restroom breaks so I would put on those old plastic backed baby diapers that were all plastic backed years ago.
I wore the old Luvs diapers with barney on them and they held up pretty good and I could fit in the largest sized old style Luvs baby diapers.
I loved the crinkly sound of those diapers and that's why I love plastic backed adult diapers today.
