Queer theory is derived largely from post-structuralist theory, and deconstruction in particular. Starting in the 1970s, a range of authors brought deconstructionist critical approaches to bear on issues of sexual identity, and especially on the construction of a normative "straight" ideology. Queer theorists challenged the validity and consistency of heteronormative discourse, and focused to a large degree on non-heteronormative sexualities and sexual practices. The term "queer theory" was introduced in 1990, with Eve Kosofsky Sedgwick, Judith Butler, Adrienne Rich and Diana Fuss (all largely following the work of Michel Foucault) being among its foundational proponents.

The gender binary, also referred to as gender binarism (sometimes shortened to just binarism), is the classification of sex and gender into two distinct, opposite and disconnected forms of masculine and feminine. It is one general type of a gender system. As one of the core principles of genderism, it can describe a social boundary that discourages people from crossing or mixing gender roles, or from identifying with third (or more) forms of gender expression altogether. It can also represent some of the prejudices which stigmatize intersex and transgender people, especially those that are genderqueer-identified — individuals who may not always fit neatly into the gender binary..

A gender role is a set of social and behavioral norms that are generally considered appropriate for either a man or a woman in a social or interpersonal relationship. There are differences of opinion as to which observed differences in behavior and personality between genders are entirely due to innate personality of the person and which are due to cultural or social factors, and are therefore the product of socialization, or to what extent gender differences are due to biological and physiological differences.
Gender roles differ according to cultural-historical context, and while most cultures express two genders, some express more. Androgyny, for example, has been proposed as a third gender. Others societies have been claimed to have more than five genders, and some non-Western societies have three genders – man, woman and third gender. Gender expression refers to the external manifestation of one's gender identity, through "masculine," "feminine," or gender-variant or gender neutral behavior, clothing, hairstyles, or body characteristics.

Pansexuality, or omnisexuality, is sexual attraction, sexual desire, romantic love, or emotional attraction toward people of all gender identities and biological sexes. Self-identified pansexuals may consider pansexuality a sexual orientation, and refer to themselves as gender-blind, asserting that gender and sex are insignificant or irrelevant in determining whether they will be sexually attracted to others. The Oxford English Dictionary defines pansexuality as, "not limited or inhibited in sexual choice with regard to gender or activity".The concept of pansexuality deliberately rejects the gender binary, the "notion of two genders and indeed of specific sexual orientations", as pansexual people are open to relationships with people who do not identify as strictly men or women

Sexual orientation is an enduring personal quality that inclines people to feel romantic or sexual attraction (or a combination of these) to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender. These attractions are generally subsumed under heterosexuality, homosexuality, and bisexuality, while asexuality (the lack of romantic or sexual attraction to others) is sometimes identified as the fourth category. These categories are aspects of the more nuanced nature of sexual identity. For example, people may use other labels, such as pansexual or polysexual, or none at all. According to the American Psychological Association, sexual orientation "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions". The term sexual preference largely overlaps with sexual orientation, but is generally distinguished in psychological research. A person who identifies as bisexual, for example, may sexually prefer one sex over the other.
Sexual fetishism, or erotic fetishism, is the sexual arousal a person receives from a physical object, or from a specific situation. The object or situation of interest is called the fetish; the person who has a fetish for that object/situation is a fetishist. A sexual fetish may be regarded as an enhancing element to a romantic/sexual relationship "achieved in ordinary ways (e.g. having the partner wear a particular garment)" or as a mental disorder/disorder of sexual preference if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Arousal from a particular body part is classified as partialism.
Fetish culture is the lifestyle and arts relating to and influenced by the interest in sexual fetishism and paraphilias. This includes fetish magazines, and a particular style of fashion, photography, art and modelling. Also within fetish culture is a nightclub scene that is served by fetish clubs. The first feature film shown around the world at film festivals and in cinemas that was principally set in the fetish lifestyle and subculture was the 1997 UK production Preaching to the Perverted (film), written and directed by Stuart Urban and starring Guinevere Turner. Filmed in a cartoon, high camp style, the film was also a political satire inspired by actual prosecutions of fetish clubs and BDSM lifestyle practitioners such as Operation Spanner. It encountered censorship problems in the UK and USA and was the last film banned in Ireland in the twentieth century. Originally it was developed by the BBC, who deemed the script "unbroadcastable" and withdrew. Within just a few years, it was actually screened several times on the BBC.
