Sexual orientation is distinct from other components of sex and gender, including biological sex which is the anatomical, physiological, and genetic characteristics associated with being male or female, gender identity which is the psychological sense of being male or female, and social gender role which is the cultural norms that define feminine and masculine behaviour.

The American Psychological Association (2008) notices that sexual orientation is closely tied to the intimate personal relationships that meet deeply felt needs for love, attachment, and intimacy.
