I started with a panty fetish around age 4. I was at a girl cousin's house, wet myself and ended up going home wearing a pair of her panties. Somehow these panties stayed in my underwear drawer and I cycled through them on a regular basis - except that I noticed that they felt different, Better than my regular underwear.
I experimented as any kid does going through puberty, although I was clueless and even gave myself a UTI, which was embarrassing because I knew what I did...
One night I intentionally wet my underwear and, instead if doing the right thing - washing then out and finding a place for them to dry, I put them in a jar in the back of my closet. Of course I got busted.
Throughout my life, i kept coming back to wetting and panties, never quite understanding the desire - which I loved while experimenting / playing. Then one evening I stumbled upon a diaper site and was so powerfully aroused that I pretty much ran to the nearest convenience store and bought a pack.
I drink a lot of water, so once getting them home it was easy to start soaking them. All I can say is WOW! What a joyous feeling!! I did eventually crash, and woke up the next day with a heavy trash bag full of wet diapers that I discretely had to dispose of. I did also wondered what was wrong with me....
That said, I still enjoy them and would never give up my diapers!
