My interest in diapers began when I was about 3, or 4 years old.
A short time after I was potty trained, I ended up finding a package of diapers hidden in a cedar chest and started wearing them from time to time, until my mother scolded me for it, but this never stopped my interest with them.
About a year or two, later, (I was 4 or 5) I was playing in our next door neighbor's back porch with a girl who looked to be about a year or two younger at the time and out of curiosity, (you know how young people can be at that age) I peeked up her dress and saw that she was wearing a diaper.
Moving ahead to when I was 6 or 7, maybe 8, I ended up wetting the bed for a few nights, but was dry, afterwards.
Also at that time, I was taking up cross country skiing as a winter activities thing in grade school and while I was skiing, I wet my snowpants.
At the age of 12, I saw a commercial for Attends Briefs and my desire to wear diapers again came back in full force.
At the age of 14, I wanted to wet the bed again, and one day, I did.
Gradually, through the course of my teenage years, my interest in diapers, (while still being a well guarded secret from my friends and family) started to evolve into a fetish.
At the age of 22, I started buying wearing adult diapers, on and off for about 10 years to date.
And the rest, is history.
