Sexuality, Gender Identity, Romantic Relations, and Intimacy Among Individuals with Autism Spectrum Disorder: A Narrative Review of the Literature

Sexual health is a vital aspect of overall well-being, yet individuals with autism spectrum disorder (ASD) face significant stigma and discrimination, affecting self-esteem, relationships, and sexual expression. This review examined the recent literature (2020–January 2024) on intimacy and sexuality among adolescents and young adults with ASD, incorporating 32 studies. Findings highlight poorer sexual health among autistic individuals compared to the general population, with difficulties in forming romantic relationships and navigating sexual interactions due to hypersensitivity. Autism is also linked to non-conforming gender identities and asexuality, exposing individuals to dual stigma within the LGBTQ+ community. Autism-related traits hinder sexual health knowledge, increasing risks of victimisation, abuse, and sexually transmitted infections. Comprehensive sexual education and inclusive support are crucial to address these challenges and promote sexual well-being for autistic individuals.
