Sexual attitudes and knowledge of high-functioning adolescents and adults with autism.

Ousley et al. (1991) asked high-functioning autistic teens and adults the same questions they asked peers with intellectual disability. They wanted to see who knew more about sex and who had actually dated or had partners.

Everyone filled out a survey. The team also checked IQ scores to see if smarter people knew more.

Both groups knew the same amount and said they were equally interested in sex. The autistic group had done less in real life—fewer dates, fewer partners.

Higher IQ meant more sexual knowledge in both groups. Autism itself did not lower knowledge.

Hellemans et al. (2007) and McMillan et al. (1997) later asked similar questions in group homes. They found most autistic adults do masturbate and some have relationships. These studies add real-world detail but do not contradict Y et al.—they simply show what happens when staff support is present.

García-López et al. (2016) looked parent-reports and saw autistic teens lag behind peers with Down syndrome. That sounds opposite, but parents were rating behavior, not asking the teens directly. Different source, different story.

Pownall et al. (2012) and Holmes et al. (2019) show parents delay sex talks with disabled teens. Y et al. helps explain why: parents may assume low knowledge when actual knowledge is equal to peers.

Do not assume your autistic client knows less about sex—test first. Use the same assessment you would for any teen. If knowledge is solid but experience is missing, shift goals to social scripts, dating practice, and safety in public places. Share Y et al. with parents to calm fears that talking about sex will create interest—it is already there.
