Sensory Processing Differences Linked to Higher Sexual Distress in Autistic Adults

A quantitative study published in the *International Journal of Sexual Health* examined how sensory processing differences—both hypersensitivity and hyposensitivity—relate to sexual distress, sexual function, and relationship satisfaction among autistic adults. Researchers Gabriella Rose Petruzzello, a doctoral student at the University of New Brunswick, and Barbara D’Entremont recruited 144 English-speaking autistic participants who were in a romantic relationship of at least three months. Participants, aged 21 to 72, resided in the United States, United Kingdom, Canada, or Australia. The sample comprised roughly 50 % women, 41 % men, and the remainder non-binary, gender-queer, or agender; about 70 % held a formal autism diagnosis while the rest were self-diagnosed.

• Sexual distress: Both hypersensitivity and hyposensitivity showed a moderate positive association with higher sexual distress, yielding a medium effect size.

Psypost

• Sexual function impairments: Approximately 33 % of participants reported difficulties in at least one domain of sexual function (e.g., arousal, lubrication).

Psypost

• Gender-specific distress: Two-thirds of autistic women exceeded the cutoff for high sexuality-related personal distress.

Psypost

• Specific challenges: Around 14 % reported a very weak sex drive, a smaller fraction reported no drive, and over 10 % indicated severe difficulty achieving arousal, lubrication, or erectile function.

Psypost

• Indirect pathway: Sensory processing differences were not directly linked to sexual function or overall relationship satisfaction. Instead, they predicted higher sexual distress, which in turn forecasted lower sexual and romantic satisfaction.

Psypost

The findings suggest that unmet sensory needs can generate emotional distress that undermines intimacy, rather than sensory differences acting as a direct barrier to satisfying relationships. Addressing sensory preferences—through tailored communication strategies, education, and therapeutic interventions—could reduce anxiety, improve sexual self-efficacy, and enhance overall relational well-being for autistic adults.

Petruzzello emphasized that the study fills a notable gap in quantitative research on sensory processing and intimate outcomes for autistic individuals. She noted that the results held regardless of whether participants had a professional diagnosis or were self-identified, thanks to a screening tool confirming high autistic traits. The authors highlighted the need for cross-cultural investigations and for programs that help autistic adults articulate sensory needs to partners and clinicians.

The study’s cross-sectional design prevents definitive causal claims; heightened distress could heighten sensory awareness rather than the reverse. The sample skewed toward highly educated, employed, and predominantly white participants, introducing potential survivorship bias because only those in relationships of at least three months were eligible. Consequently, the experiences of single autistic adults or those in less stable partnerships may be under-represented. The authors also called for broader inclusion of diverse racial, ethnic, and LGBTQ + populations in future work.

While sensory processing sensitivity correlated with sexual distress, no direct statistical relationship emerged between sensory differences and sexual function or overall satisfaction. This indirect association underscores a gap in understanding the mechanisms by which sensory experiences translate into relational outcomes.

Psypost

• “There was a major gap in the literature on how sensory processing sensitivity, including both hyposensitivity and hypersensitivity, were related to outcomes like sexual and relationship satisfaction, sexual distress, and sexual function in autistic adults,” — Gabriella Rose Petruzzello, Doctoral Student, University of New Brunswick

Psypost

• “While both forms of research are invaluable, our study is able to provide concrete statistics about the magnitude and presence of effects,” — Gabriella Rose Petruzzello

Psypost

• “In addition to the findings on sensory processing and sexual distress, we also found that around 33% of autistic adults in our study reported impairments to sexual function in one or more domains (e.g., arousal, lubrication) and that two-thirds of autistic women were above the cutoff that marks high levels of sexuality-related personal distress,” — Gabriella Rose Petruzzello

Psypost

• “The key takeaway from this study is that both forms of sensory processing sensitivity were related to elevated sexual distress,” — Gabriella Rose Petruzzello

Psypost

• “The study only included one time point so we can’t make claims that sensory processing differences cause individuals to be more distressed,” — Gabriella Rose Petruzzello

Petruzzello and D’Entremont plan to publish additional analyses from the dataset and to develop educational resources and clinical therapies aimed at helping autistic adults manage sensory needs within intimate contexts.
