Sexuality remains a neglected and largely taboo area within practice, but it can be a demanding aspect of social work. Social workers may be familiar with the importance of issues such as racism and ethnicity, but sexuality is also a very significant part of people's lives, closest relationships and sense of identity. This valuable resource introduces the topic, using a combination of perspectives to consider sexual diversity and examining related issues across the life-course, including sexual orientation, disability, HIV, sexual abuse, mental health and sexual exploitation. It also includes recent legislation which has significant implications for social work practice.
