Being a person on the Autism Spectrum, I seem to have a different perspective regarding being a "Little" who is an "Adult Baby". For me, being an Adult baby is not in any way a sexual fetish. It is integrated into my "core personality", which was forged through the adversity of being the multiply handicapped Eldest Son of an "untreated" mentally-ill parent (my Mother). My own "real childhood" was "never normal". As I aged into adulthood, my "inner child" got "fused on the outside", instead of remaining "hidden away".
I will honestly admit to always having a deep aversion towards the "adult world". Yes! I do have to perform adult tasks, such as driving a motor vehicle, going shopping, and paying bills. Also, I did until right after the Terrorist Attacks of September 11, 2001 had employment intermittently since 1978, but the last 12 1/4 years, I slipped into permanent unemployment and had to take Social Security in 2006 at the age of 48.
Despite my adult appearance as an Autistic with Cerebral Palsy, I have always cognitively socially functioned at the level of a boy of age 8 to 10 years of age.
Instead of the normal pursuits of adulthood, I have always been more interested in collecting and playing with toys, and have never had much if any interest in any mature cognitive functioning tasks, such as dating or relationships. Yet, at best, I only understand my having a basic attraction to only adult males of my own physical age. With my cognitive social functioning level so low at the level of an 8 to 10 year-old boy as an autistic, I at my physical age of 55, still think of sex and sexuality as a "grown up thing", which I will never understand.
Darn! I still think that the opposite sex is "yucky", and I still really do not understand where babies really come from. I feel I have never had the right to really know that.
I live my life now as mostly a "Little", with intermittent times when necessary to perform "adult" cognitive tasks.
My life as an older Autistic with Cerebral Palsy is one of spending lots of my time in simple cognitive play with my toy cars and trucks, and my NERF Toy Guns, and my LEGO Bricks, and my G. I. Joe Army Guys, and my little Plastic Army Men, and other toys.
I play alone, because there are no other autistics around to come over to play with me.
I am lonely.
I simply never want to ever harm anyone.
