Overview

This lecture explains the differences between sex, gender, and orientation, highlighting the importance of up-to-date sex education and understanding diverse identities.

Sex

  • Sex refers to biological traits such as genitals, chromosomes, body hair, and secondary sex characteristics.
  • Chromosomal makeup (like XX or XY) usually determines male or female characteristics but is not always straightforward.
  • Intersex individuals may have biological traits that do not fit typical male or female classifications.

Gender

  • Gender is a social construct, shaped by cultural expectations and personal identity.
  • Gender identity is how individuals perceive themselves and their gender.
  • Gender expression is how individuals present their gender through behavior, mannerisms, and dress.
  • Societal stereotypes often associate certain traits, colors, or activities with specific genders.
  • Transgender people identify with a gender different from the one assigned at birth.
  • Non-binary or genderqueer individuals may identify with both, neither, or other gender concepts.

Orientation

  • Orientation describes who someone is attracted to, regardless of their or others' sex or gender.
  • Heterosexual people are attracted to the opposite gender; homosexual people to the same gender.
  • Bisexual people are attracted to both genders.
  • Pansexual people are attracted to others regardless of their sex or gender presentation.
  • Orientation is innate and not a conscious choice, except for whether to pursue a relationship.
