I'm a 49yo heterosexual Mum with a husband of nearly 11 years.
I'm also autistic being diagnosed 3.5 years ago after an adulthood of difficulties.
One of the difficulties I had was a confusion about my identity and sexuality through my teens and 20's.
I hated my adolescent and adult female body. I cut my hair short and dressed down typically wearing shirts and trousers/jeans. Never wore make up or made any effort with my appearance.
I felt asexual was not attracted to men or women.
I never dated or had any sexual experiences.
Then in my late 20's I found myself attracted to a male colleague at work. I realised I was actually heterosexual.
I however took another 5 to 6 years before I went on a date.
Around 35 to 36 I lost my virginity.
What's the point of this sorry tale you may ask yourself 
Well my point is I think their is a significant link between gender dysphoria and high functioning ASD.
I've thought this for while.
People with ASD often have problems with identity, change in general and be immature both emotionally and sexually.
If when I was a teenager and the whole trans thing was huge maybe I would have wanted to be male as I knew I didn't like being female at that time.
Looking into research on Gender Dysphoria and ASD it seems I may be right
From above:
" Young people with gender dysphoria have an elevated rate of Asperger syndrome, according to a new study.
Individuals with gender dysphoria feel distress because there is a mismatch between their physical gender and their perceived gender.
Daniel Shumer and colleagues conducted a retrospective review of patient chart data from 39 consecutive patients between 8 and 20 years of age seen at a gender clinic. Of this group, 22 were biologically male and 17 were biologically female. The researchers report, “Overall, 23.1% of patients (9 of 39) presenting with gender dysphoria had possible, likely, or very likely Asperger syndrome as measured by the Asperger Syndrome Diagnostic Scale (ASDS).”
However, the researchers say their findings “are consistent with growing evidence supporting increased prevalence of ASD [autism spectrum disorders] in gender dysphoric children.” "
I think people need to know about this especially parents of kids who think they have gender dysphoria.
