I alao have high-functioning autism: never asked when I got out of diapers, was never told when but knew I wanted right back in diapers as soon as I got out of them...specifically for comfort. Pampers were always my favorite, esp. for their incredible softness and wonderful, babyish perfume scent.
As far as school, never wore to school; also, had a cousin who was regularly diaper-punished (cloth), was always jealous of him. Aside from all that, I had a reputation for high intelligence but poor organization so grades were average. 5-time National Spelling Bee school champ, sent to regional semi-finals. Excelled in Drafting/CAD, 2-year program during high school.
After graduating, began enlistment in Army, took ASVAB and blew the recruiter & tester both away: all but one category were in the 90-percentile (other was 89), had 96s-99s. The base psychiatrist projected an IQ estimate of 140-150...and I was stunned when the Air Force showed up the next day, begging me to enlist with them! But went Army instead, got sent home during Basic due to Gramm-Rudman-Hollings Act cuts.
Back to basics: I had high intelligence, poor organization, poor social skills, learned academics rapidly but vocational training was slow. Not until just over a year ago, not until after turning 52 did I learn this mixed blessing/curse was autism. It blew me away, it played with my head awhile but it finally settled in. It explained everything.
Granted, not all people with autism are Diaper Lovers and not all Diaper Lovers have autism...but it would be quite interesting to see where the slider would end up if there were numbers on the subject.
