Purpose: To explore perceptions of nurses and patients regarding sexual intimacy in a long-term mental health unit.

Findings: The theme of supporting sexual intimacy was identified and described in this paper and included the following subthemes for nurses: It depends on the setting, need for guidelines and consent, and for patients—it depends on the setting; and need for support. Practice Implications: The findings suggest that current guidelines regarding sexual intimacy in acute inpatient settings may not be appropriate in long-term facilities, with a need for guidelines to specifically address this setting. Furthermore, support for sexual intimacy needs of patients was identified as a strong need for patients and they believed not currently met. Nurses have an important role to play as part of their holistic approach to care and barriers to providing this aspect of care must be overcome to ensure patients' rights are respected.
