to be honest, i can't remember a time i did'nt like wearing diapers, even when i was 4 or 5, i would put pull-ups on way before i was going to bed (i had a wet the bed problem) which is where i beleive it stems from. most kids who have a problem like that, are embarrassed, and don't like wearing them, i on the other hand, loved wearing them. As i was growing up, and going through puberty (10-12) i discovered sexual urges, etc. and around 12, it started becoming somewhat of a fetish, my brother was small at the time, and i would sneek his diapers, eventually my mom found out, and forbid me from even wearing pull-ups to bed. Eventually around 13, i would go to freinds houses in town, ride bikes around the town and what have you, and i would go into stores and take some out of the bag, it was my only means of aquareing them, eventually i was old enough to work, and buy them myself, and now i am here today, a full fleged ab/dl.
