Abstract
Sexual orientation subsumes sexual attractions, sexual behavior, psychological and emotional attachments, self-identification, and affiliations with a particular community. These elements are often overlooked in the use of terms such as lesbian or heterosexual. In this activity, students categorized the sexual orientation of 10 fictional people, some of whom presented inconsistencies between different aspects of their sexuality. By illustrating the difficulty in defining rigid and consistent categories of sexual orientation, the activity stimulates animated discussion and receives positive feedback from students. I use this activity in teaching the Psychology of Women, Sexual Behavior, and the Psychology of Sexual Orientation, although instructors could use it in other courses as well.
