4.1 Defining and understanding sexual orientation

Sexual orientation is a complex aspect of human sexuality, encompassing attraction, behavior, and identity. It exists on a spectrum, with heterosexuality, homosexuality, and bisexuality being the most recognized orientations. However, there's a growing awareness of other identities like pansexuality and asexuality.

Understanding sexual orientation involves exploring its components, historical context, and cultural variations. It's distinct from biological sex and gender identity, and doesn't always align with sexual behavior. Factors like social norms, religion, and fear of discrimination can influence how people express their orientation.

1 of 3

• Sexual orientation refers to an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes, and the genders that accompany them
• The three main components of sexual orientation include:
  • Attraction: Who a person is drawn to romantically or sexually
  • Behavior: Who a person engages in sexual activity with
  • Identity: How a person labels their sexual orientation
• Sexual orientation exists along a continuum, with exclusive attraction to the opposite sex on one end and exclusive attraction to the same sex on the other, and varying degrees of bisexuality in between

Distinction from other aspects of sex and gender

• Sexual orientation is distinct from other components of sex and gender, including:
  • Biological sex: The physical attributes that characterize male, female, and intersex bodies
  • Gender identity: A person's inner sense of being male, female, neither, or other genders
  • Social gender role: The behaviors, attitudes, and personality traits considered appropriate for males and females by a particular culture

Sexual orientation vs identity vs behavior

Differences between orientation, identity, and behavior

• Sexual orientation encompasses attraction, fantasy, emotional connections, and self-identification, while sexual behavior specifically refers to sexual acts performed
• Sexual identity refers to how one thinks of oneself in terms of to whom one is romantically or sexually attracted, which may not always align with sexual orientation or sexual behavior
• An individual's sexual orientation identity, sexual behavior, and sexual desire may be congruent or incongruent with each other

Factors influencing expression of orientation in behavior

• Individuals may or may not express their sexual orientation in their behaviors due to various factors such as:
  • Social norms and expectations
  • Religious beliefs
  • Internalized stigma or homophobia
  • Fear of discrimination or violence
  • Lack of opportunity
  • Situational contexts (prisons, single-sex schools)

Spectrum of sexual orientations

Kinsey scale and sexual orientation continuum

• The Kinsey scale, developed by Alfred Kinsey, is a numeric scale ranging from 0 (exclusively heterosexual) to 6 (exclusively homosexual) that is used to describe a person's sexual orientation based on their experience or response at a given time
• It represents sexual orientation as a continuum rather than distinct categories, with many people falling somewhere between the two extremes

Major sexual orientation identities and their prevalence

• Heterosexuality (straight): Attraction to members of the opposite sex
  • Most common orientation, comprising 85-90% of the population according to most studies
• Homosexuality: Attraction to members of one's own sex
  • Gay: Men attracted to other men
  • Lesbian: Women attracted to other women
  • Prevalence estimates range from 1.2-6.8%, with most around 3-4%
• Bisexuality: Romantic or sexual attraction to both men and women, or to more than one sex or gender
  • Prevalence estimates range from 1.5-6.9%
• Less common orientations are becoming more widely recognized, such as:
  • Pansexuality: Attraction regardless of gender
  • Asexuality: Not experiencing sexual attraction
  • Queer: Umbrella term for non-heterosexual orientations
  • Questioning: Exploring one's sexual orientation identity

Historical and cultural context of sexual orientation

Emergence of sexual orientation as a concept

• The concept of sexual orientation emerged in the late 19th century, with the terms "homosexuality" and "heterosexuality" first used in 1869
• Prior to the 19th century, sexuality was largely defined in terms of sexual acts and behaviors rather than as an identity or orientation

Changing cultural attitudes and scientific study

• Homosexuality was considered a mental disorder in the DSM until 1973, reflecting prevailing cultural attitudes of the time period
• The Kinsey Reports, published in 1948 and 1953, were some of the first to study sexual orientation and behavior from a scientific perspective and challenge prevailing beliefs
• Cultural attitudes towards sexual orientation have shifted over time, with increasing acceptance and rights for LGBT individuals in many parts of the world

Cultural variations in sexual orientation identities

• Sexual orientation identities are influenced by cultural and historical factors
• Some cultures have identities that do not fit within Western conceptions of orientation, such as:
  • "Two-spirit" in Native American cultures
  • "Kathoey" in Thailand
  • "Hijra" in South Asia
• The expression and acceptance of different sexual orientations varies widely between cultures and time periods
