Sex and sexuality
Sex refers to physical and biological traits—whereas gender refers especially to social or cultural traits—and the physiological and psychological processes related to procreation and sexual pleasure.
Sexuality is the capacity to derive pleasure from various forms of sexual activity and behavior, particularly from sexual intercourse. It can also include all aspects of sexual behavior, including gender identity, orientation, attitudes, and activity.
