I've always been partially incontinent, and for all my life i've held it in too long because i didn't want to go to the bathroom every hour. I believe the resaon i became curious about diapers was because i had started to accidentally wet myself during the daytime. Without even realising why i was doing it, i started to enjoy wetting my underwear, and started to wonder if i could use a diaper to hold in the pee. That's probably what happened to me.
