Man in the context of "Nipple"

Gender is the range of social, psychological, cultural, and behavioral aspects of being a man (or boy), woman (or girl), or third gender. Although gender often corresponds to sex, a transgender person may identify with a gender other than their sex assigned at birth. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other; those who are outside these groups may fall under the umbrella term non-binary. Some societies have third genders (and fourth genders, etc.) such as the hijras of South Asia and two-spirit persons native to North America. Most scholars agree that gender is a central characteristic for social organization; this may include social constructs (i.e. gender roles) as well as gender expression.

The word has been used as a synonym for sex, and the balance between these usages has shifted over time. In the mid-20th century, a terminological distinction in modern English (known as the sex and gender distinction) between biological sex and gender began to develop in the academic areas of psychology, sociology, sexology, and feminism. Before the mid-20th century, it was uncommon to use the word gender to refer to anything but grammatical categories. In the West, in the 1970s, feminist theory embraced the concept of a distinction between biological sex and the social construct of gender. The distinction between gender and sex is made by most contemporary social scientists in Western countries, behavioral scientists and biologists, many legal systems and government bodies, and intergovernmental agencies such as the WHO. The experiences of intersex people also testify to the complexity of sex and gender; female, male, and other gender identities are experienced across the many divergences of sexual difference.

The Creation of Adam (Italian: Creazione di Adamo), also known as The Creation of Man, is a fresco painting by Italian artist Michelangelo, which forms part of the Sistine Chapel's ceiling, painted c. 1508–1512. It illustrates the Biblical creation narrative from the Book of Genesis in which God gives life to Adam, the first man. The fresco is part of a complex scheme and is chronologically the fourth in the series of panels depicting episodes from Genesis.

The painting has been reproduced in countless imitations and parodies. Michelangelo's Creation of Adam is one of the most replicated religious paintings of all time.

A boy is a young male human. The term is commonly used for a child or an adolescent. When a male human reaches adulthood, he is usually described as a man.

Facial hair is hair grown on the face, usually on the chin, cheeks, bottom lip and upper lip region. It is typically a secondary sex characteristic of human males. Men typically start developing facial hair in the later stages of puberty or adolescence, at around fourteen years of age, and most do not finish developing a full adult beard until around sixteen or later. However, large variations can occur; boys as young as ten have also been known to develop facial hair, and some men do not produce much facial hair at all.

Men may style their facial hair into beards, moustaches, goatees or sideburns; many others completely shave their facial hair and this is referred to as being "clean-shaven". The term whiskers, when used to refer to human facial hair, indicates the hair on the chin and cheeks.

A monk (/mʌŋk/; from Greek: μοναχός, monachos, "single, solitary" via Latin monachus) is a man who is a member of a religious order and lives in a monastery. A monk usually lives his life in prayer and contemplation. The concept is ancient and can be seen in many religions and in philosophy across numerous cultures.

The Greek word for "monk" may be applied to men or women. In English, however, "monk" is applied mainly to men, while nun is typically used for female monastics.

Gentleman (Old French: gentilz hom, "gentle man"; colloquial: gent) is a term for a chivalrous, courteous, or honorable man. Originally, gentleman was the lowest rank of the landed gentry of England, ranking below an esquire and above a yeoman; by definition, the rank of gentleman comprised the younger sons of the younger sons of peers, and the younger sons of a baronet, a knight, and an esquire, in perpetual succession. As such, the connotation of the term gentleman captures the common denominator of gentility (and often a coat of arms); a right shared by the peerage and the gentry, the constituent classes of the British nobility.

Thus, the English social category of gentleman corresponds to the French gentilhomme (nobleman), which in Great Britain meant a member of the peerage of England. English historian Maurice Keen further clarifies this point, stating that, in this context, the social category of gentleman is "the nearest contemporary English equivalent of the noblesse of France." In the 14th century, the term gentlemen comprised the hereditary ruling class, which is whom the rebels of the Peasants' Revolt (1381) meant when they repeated:
