In the current intersectionality-focused discourse within sexuality research, individuals existing at the convergence of intellectual and developmental disabilities (IDD) and lesbian, gay, bisexual, transgender, and queer+ (LGBTQ+) are often overlooked. Individuals with IDD face difficulties acquiring sexual knowledge and skills due to limited opportunities for sexual socialization, misconceptions concerning sexuality and IDD, lack of comprehensive sexual education, restricted support from staff and caregivers, and a lack of community experiences that facilitate the development of healthy sexuality. When an individual with IDD identifies as LGBTQ+, these disability-related barriers can exacerbate the stigma and discrimination some LGBTQ+ people experience. Using the intimate justice framework, we explore avenues to support and foster inclusivity within the LGBTQ+ community for members with IDD. Several recommendations were identified from the literature search, including logistical considerations and using accessible language for outreach events, presentations, workshops, training, and other activities and opportunities for sexuality education while challenging disability-related stigma in LGBTQ+ spaces.
