Thanks for supporting us, Ellie.
If you need specificity, in your research, I'd focus on women rather than men, and adults, rather than children. There's superfluous research into boys with autism, and many people consequently believe that autism exists only in boys. Ugh.
Empathy and affection might be interesting topics, when correlated with autism.
Many people, with autism, are viewed as unempathetic, because we, on average, manifest less empathy than neurotypical people, but that doesn't mean that we lack empathy.
Also, this thread title got me thinking about autism and affection. I personally enjoy touching and being touched (eg. hugs, pats on the back), which contradicts a trait frequently observed, in autistic people: touch aversion. If I get a hug from someone I like, I feel tingly, giddy, and can't stop smiling and giggling. When touching (or being touched by) people I don't mind, I neither flinch nor scare.
