Sex. Gender. and Sexuality
Sex describes genetic sex, gender describes the societal constructs gender identity and gender role, and human sexuality describes sexual preference.
- Sex is both genetic (what genes a person has and how they express) and epigenetic (how genes express and how environmental factors effect genes). Biological sex depends on the genes a person has and how those genes express to create physiological differences (like a penis or vagina). Biological sex is not thought to be affected by environmental factors.
- Gender refers to societal constructs of gender identity (how a culture perceives a person and how a person perceives themselves) and gender roles (a set of societal norms based on actual or perceived sex, gender, or sexuality).
- Sexuality refers to personal preference regarding human sexuality (which comes in a variety of flavors based on nature and nurture).

Sex, Gender, and Sexuality Are Binary Myth
Studies have shown there is no single determinant of sex, gender, or sexuality. In terms of both sex (genetic) and gender (a social construct), a binary distinction of “male or female” fails to describe a wide range of humans in practice. Meanwhile, sexuality (a preference) eludes any simple categorization as well. Simply put, despite some binary aspects (for example a person either has a Y gene or they don’t), Gender, Sex, and Sexuality are all non-binary and each is instead a complex spectrum… and we can prove it with science and logic.
