Ah yes, I remember the first couple times when I was a teenager. What a thrill, what a feeling. When its happening you kind of wish it would end, but being older I miss those feelings. Embrace it like a superpower. Embrace your fetish like a superpower.
When I told my best friend about being ABDL when I was younger, he was cool about it despite never hearing about it before, but what I remember most was him saying how he wished he had a fetish! Some of us wish we were just "normal vanilla", but that it gives us a unique ability to shut out the world. It allows you to fully trust your own feelings and self wholeheartedly for your own desires. It teaches you to be a confident person out in the world in social and work situations. In realizing that so many other people have inner desires, most don't know about you and you'll never know about the high heels in someone's closet, the pictures of feet under the bed, that a colleague masturbated with a balloon before she brought you a coffee. The silly thing to think about is how many humans supress their weird inner desires and never get a chance to figure them out. They never get the bliss, the sexual intensity, the warm, caring, loving feeling that diapers give us. It is sexual, it is meditiative, it is comfort, it is love when you find another to embrace it with you.
First, embrace it yourself and you never feel ashamed. If you do, turn it into a positive; I'm turned on by the thought of embarassing situations where I'm forced to be a baby! Its helped me just dive-in to things that I'm afraid to do or that I'm worried of embarassment. Fall down, get back up. Obvious thigns that the mind forgets often. The only way to not be embarassed by things in life is to follow through with doing things that embarass you. Embarass yourself to embrace yourself. Wear diapers and prosper.
P.S. I hate that you got pre-schools because they have been sold out in Canada for 6 months so screw you ;-)
