Masculinity (also called boyhood, manliness, or manhood) is a set of attributes, behaviors and roles generally associated with boys and men. Masculinity is socially constructed, but made up of both socially-defined and biologically-created factors,distinct from the definition of the male biological sex. Both males and females can exhibit masculine traits and behavior. Those exhibiting both masculine and feminine characteristics are considered androgynous, and feminist philosophers have argued that gender ambiguity may blur gender classification.
Masculine traits include courage, independence and assertiveness. These traits vary by location and context, and are influenced by social and cultural factors. An overemphasis on masculinity and power, often associated with a disregard for consequences and responsibility, is known as machismo.
Masculine qualities, characteristics or roles are considered typical of, or appropriate for, a boy or man. They have degrees of comparison: "more masculine" and "most masculine", and the opposite may be expressed by "unmanly" or "epicene". Similar to masculinity is virility (from the Latin , "man"). The concept of masculinity varies historically and culturally; although the dandy was seen as a 19th-century ideal of masculinity, he is considered effeminate by modern standards. Masculine norms, as described in Ronald F. Levant's Masculinity Reconstructed, are "avoidance of femininity; restricted emotions; sex disconnected from intimacy; pursuit of achievement and status; self-reliance; strength and aggression, and homophobia." These norms reinforce gender roles by associating attributes and characteristics with one gender.
