Yes it's normal to want to wear diapers even though you don't need to wear them for urinary or fecal incontinence.
I started loving to wear diapers at around age 5 years old after I was potty trained at age 3.
I believe what brought my love for diapers on is that I was at a babysitters house when I was 5 years old which was in the year `1993.
I was shy and hated going to other peoples houses or into their bathrooms.
So I tried holding in my pee and eventually I started wetting my pants sitting on the babysitters couch.
So the babysitter took me into her bathroom, removed my pants, underwear and shirt and threw them in the washing machine.
Then she gave me a bath and after drying me off she grabbed a Pampers diaper which was plastic backed then and put me in the diaper.
Since my clothes were in the washing machine she sent me back out into the living room wearing just the diaper.
I wore the diaper until my sister came and picked me up and took me home.
I walked home with my sister wearing just my socks, shoes and the diaper.
The walk home was only a few minutes but at the time I felt embarrassed.
My sister took the diaper off of me when I got home and put it in the trash and it was used a little for pee.
But when she was not looking I went back and got the diaper back out and put the diaper back on and enjoyed it.
Whenever I was at the babysitters house she would always diaper me until I was 8 years old and stopped going to that babysitter.
I was always looking forward to being diapered at her house.
I now wear diapers full time as an adult and no longer use the toilet.
I used to think I was alone in loving to wear diapers but when I got the internet around 1998 when I was 10 I searched I love to wear diapers.
That was on AOL dial up internet and surprisingly I found that a lot of people love to wear diapers so you're not alone.
