ABSTRACT
This chapter presents an overview of some of the diverse and less common expressions of sexuality the clinician is likely to encounter in sex therapy practice. As such, some clients will fall outside of the range of mainstream sexual disorders defi ned in the DSM-5 (American Psychiatric Association, 2013). The clinician should be prepared, comfortable and competent in helping clients who might appear to be gender diverse , or not conforming to gender-based expectations of society, including transgender, transsexual, intersex, cross-dresser, gay, lesbian, bisexual, kinky and so on. Therapists should not presuppose that gender-diverse clients are pursuing treatment of their specifi c gender/erotic/ sexual preference or orientation but instead might want help with other personal or relational issues.
