Adolescents with intellectual disabilities face significant barriers in accessing sexual education that meets their specific needs. Despite their recognised rights to have fulfilling lives and make independent choices, they are often wrongly perceived as asexual, hypersexual, or sexually immature. They are more likely to experience unintended pregnancies and higher exposure to sexually transmitted infections, along with difficulties in forming healthy relationships. Current relationship and sexuality education (RSE) programmes tend to focus more on biology, risky sexual behaviours, and consent without sufficient attention to intimacy, relationships, and informed decision-making. These gaps leave young people with intellectual disabilities vulnerable to sexual abuse and mental health issues. Therefore, this brief aims to identify strategies that might help to overcome these challenges by developing inclusive, outcome-focused comprehensive sexuality education programmes that empower adolescents with intellectual disabilities and support their informed choices.
