Sexual orientation, asexuality and sex education

Autistic adolescents and adults report a wider range of sexual orientations than non-autistic people. The largest survey, of 2,386 adults, found that autistic people were less likely to describe themselves as sexually active or heterosexual, and more likely to report asexuality or another orientation.² The size of the difference varies between studies and with who was asked.

In a smaller international online sample of 309 autistic adults and 310 non-autistic adults, 69.7% of the autistic group and 30.3% of the comparison group reported an orientation other than heterosexual.¹ Both groups were mostly women, 219 of 309 and 226 of 310, and everyone in the survey chose to answer it. Those two groups did not differ in the age at which they first had sex or in rates of sexually transmitted infections.²

In a Dutch sample of 675 autistic adolescents and adults registered in the Netherlands Autism Register, compared with 8,064 general-population peers from a national sexual-health survey, more autistic people, especially women, reported attraction to both same- and opposite-sex partners.³

A population-based study in Stockholm County asked 47,356 adults about autistic traits and sexual orientation. People who scored above the threshold on a short autism questionnaire were more likely to identify as bisexual, and more likely to say their orientation could not be described as heterosexual, homosexual or bisexual.⁵ The autism measure was a ten-item screen, not a diagnosis.

A whole-population study in New Zealand linked Census 2023 records for 1,266,453 young people. It reports autism rates within orientation groups, not the share of autistic people who are non-heterosexual, so it cannot be read alongside the surveys above. Autism was identified in 2.42% of non-heterosexual young people and 1.37% of heterosexual young people, which the authors report as 1.8 times as high; adjusted for age, ethnicity, deprivation and urban or rural residence, the estimates were 2.2% and 1.4%.⁴ The question about sexuality was asked only of those aged 15 and over, and about 27% of answers to it were missing.

Some autistic people report little or no sexual attraction. In the international sample, autistic adults reported higher rates of asexuality than non-autistic adults,¹ and in the larger online survey autistic people were more likely to report asexuality or another orientation.² A systematic review of the autism and asexuality literature found asexuality reported more often in autistic samples and found that the two share some features, such as sexual desire not aimed at a partner; it concluded that the link is not yet clarified and called for more research.⁶

Asexual and aromantic people may still want close relationships. In community writing they describe committed partnerships without sex or romance (see below).

Sex education is usually written for non-autistic students, and autistic adults describe it as a poor fit. A systematic review of 56 studies found that autistic people share typical sexual desires, that sensory sensitivities and communication difficulties can complicate relationships, and that tailored sexual-health education is needed.⁷ In interviews, nine autistic young adults from different cultural groups said the sexuality and relationship education they had received had paid little attention to culture, and called for teaching that was consistent and built for them.⁸

A mixed-methods study of autistic and non-autistic college students found that autistic students were less satisfied with the consent education they had received. In the same study, difficulty in recognizing one's own desire to consent appeared in both groups, and autistic participants described realizing only later that an assault had happened.⁹

The staff who provide this education shape what is offered. In interviews with 20 special-education staff in Israel, researchers found stigmatizing views about whether autistic adolescents could form relationships, and a tendency to treat sex education as prevention above all.¹⁰

Autistic young people use sexual and reproductive health services less than their peers. A population-based study in Stockholm County followed 454,405 young people aged 12 to 22, 11,850 of them autistic. Autistic youth were less likely to have an in-person visit than their peers, with the gap larger for males. Among autistic females who did use the services, the amount of care was similar to other young women, and the authors suggest, from that comparison, that the barrier may be getting into care at all; the difference was smaller for digital visits than for in-person ones, which the authors say might help reduce the gap. Autistic females were more likely to see a doctor but less likely to see a midwife or use short-acting contraception.¹¹

A systematic review reports that autistic people face a higher risk of sexual victimization, linked to limited sexual knowledge and to other factors.⁷ The same review notes studies reporting atypical or offending sexual behavior in some autistic people, drawing on clinical and forensic case material as well as non-clinical samples; these samples are not representative, and the finding is not established. Sexual victimization, and what helps, is covered in Safety and mate crime.

Several reasons have been proposed for why autistic people report more diverse sexual orientations, and none is well tested. One proposal was first made for the overlap with gender diversity: that autistic people are less bound by social conditioning, so some may be more likely to identify with or disclose an identity outside social norms rather than conform to them. Walsh and colleagues propose this "resistance to social conditioning" for gender identity (see Gender diversity and trans autistic people).¹² Extending it to sexual orientation is an inference, and no study found as of October 2026 has tested it. A systematic review of the theories for the overlap between autism and transgender or gender-diverse identities found 15 distinct theories and none with substantial support, and named resistance to social norms and weakened sex differences as the most promising; both are sometimes offered for sexual orientation too.¹⁴

A second line of work looks at what follows the overlap rather than what causes it. In a matched sample of 462 autistic adults, sexual-minority autistic adults reported more masking than heterosexual autistic adults, a small difference the authors connect to the stress of holding more than one stigmatized identity.¹³ That is a consequence of the overlap, not an explanation for it.

No study found as of October 2026 has tested whether the difference reflects how many people are non-heterosexual or how many disclose it. Some autistic writers argue that it is the second: that autistic people, already used to being different and to social rejection, are simply more likely to be open about it (see below).

Whether autistic people are more often non-heterosexual, or only more often open about it, is not settled. The population studies so far use a short trait screen or recorded diagnoses rather than a measured autistic identity, and none follows the same people over time. A representative study that did both would show how much of the difference is who answers surveys, and following the same people would show whether an autistic identity or an orientation tends to come to awareness first.

On sex education, what is missing is an evaluation of education designed with autistic people, with outcomes that autistic people themselves choose. The reviews above call for exactly this.^7,9

Many autistic writers treat a wide range of orientations, and asexuality, as ordinary parts of autistic life, and reject the idea that autistic people are not sexual. Megan Anna Neff writes that "there is an outdated stereotype that Autistic people can't be sexual or romantic," that many autistic people identify as asexual or aromantic, and that polyamory "appears to be more common" among autistic people; she suggests talking about relationship agreements early.^c1,c2 Devon Price writes that many autistic people are asexual "for the same reasons we're more likely to be gay, bisexual, transgender, or otherwise queer," pointing to honesty and to being used to standing outside social norms, rather than to a different kind of desire.^c3

Price also describes relationship forms beyond monogamous marriage, including queerplatonic partnership, a close and committed relationship with no romantic or sexual part, and borrows the term amatonormativity for the assumption that everyone wants one central romantic relationship.^c3 On consent, Price argues that autistic people may miss when their own boundaries are crossed or misread a partner's, and that the answer is explicit spoken communication; signals a non-autistic partner reads as discomfort, such as a flat expression or fidgeting, can sometimes mean an autistic person has stopped masking.^c3

Community writing on sex education asks for teaching built by autistic people. Morrigan, an autistic sexuality educator, writes that sex education made for autistic people often teaches masking and compliance rather than boundaries, and calls for education that centers pleasure and autonomy: "I would love to see sex ed for Autistic people that helps them to correctly identify that people who abuse them are responsible for their actions."^c4

Nick Walker, an autistic scholar, coined the word neuroqueer in 2008 for the practice of queering neuronormativity and heteronormativity at the same time; it can be used as a verb and as an identity label (see Neurodiversity).^c5
