Background: People with intellectual disabilities face attitudinal and service barriers when attempting to form intimate relationships. To date, their experiences and views are under-represented in the existing evidence base. Method: The aim of this study was to carry out an interpretative phenomenological analysis exploring the experience of intimate relationships for nine adults with intellectual disabilities. Results: Four main themes were identified: desiring relationships; expressing sexuality; having relationships; and who has control? Together these themes demonstrated that intimate relationships were desired and important to all participants, fulfilling a variety of their needs. In addition, participants faced a number of challenges related to intimate relationships. Conclusion: The findings raise questions about how best to support people with intellectual disabilities with sexuality and intimate relationships. Implications for caregivers and services are discussed.
