high functioning autistic straight men tend to be either:
"sapiosexuaI" without much sensual desire, their relationships are mostly just talking, if they ever have any, maybe have sex occasionally without much other physical contact
have obsessive special interests like trains, planes, cars, anime or star wars. Sometimes very useful learned skills or natural abilities surrounding their areas of autistic focus
able to talk to strangers readily, and often annoy them, like that guy who tries extra hard to be friendly and outgoing around everyone trying to make conversation, but you don't really want to talk to him, wish he would just go away but you don't want to be rude so ignore him until he fucks off, unless he actually gets in your face then you tell him to go away
unaware of their mannerisms or how socially retarded they are, like a really high degree of oblivious to the way they come off, standing too close, talking too loud, "info dumping" and having no filter
or:
hypersexual and preoccupied with girls/women from a young age, when with a gf want to hug and cuddle all the time, but not interested in having sex because it feels both less intimate and a waste of energy
not have much interest in anything, no hobbies, often just playing alone, consuming media, daydreaming about women and all kinds of things
not afraid of social interacting, but don't care for it, and generally have no emotional reaction towards people except if disgusted by their appearance and/or smell, or aroused by the sight and smell of a (female) body
very self-aware, both of their own behavior and how others perceive it, yet still unable to feign normalcy or 'mask' as the other kind may do, and prefer to avoid people because I see them react to my lack of emotional engagement as being snobby/condescending (really it's just neutral detachment with no disrespect intended)
I am the latter. I know I am not alone but feel like a rare breed, the less common type of high functioning autism
