ABSTRACT
Let us start by considering the narrower term ‘sex’, a word used frequently in everyday language in many different contexts. Most commonly it refers to:
1 biological sex, a distinction between two categories of people, defined as ‘female’ or ‘male’ in terms of particular characteristics of their bodies; and
2 ‘having sex’, a description of physical activities, generally thought of as heterosexual intercourse, linked to biological processes of reproduction.
