However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction.In modern times, emphasis on the institution of marriage, generally described as a male-female bond, has obscured pair bonds formed by same-sex and transgender couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate.These people will have dates on a regular basis, and they may or may not be having sexual relations.This period of courtship is sometimes seen as a precursor to engagement.Prior to that, courtship was a matter of family and community interest.Starting around the time of the Civil War, courtship became a private matter for couples.Still, dating varies considerably by nation, custom, religious upbringing, technology, and social class, and important exceptions with regards to individual freedoms remain as many countries today still practice arranged marriages, request dowries, and forbid same-sex pairings.Although in many countries, movies, meals, and meeting in coffeehouses and other places is now popular, as are advice books suggesting various strategies for men and women, in other parts of the world, such as in South Asia and many parts of the Middle East, being alone in public as a couple with another person is not only frowned upon but can even lead to either person being socially ostracized.
The word "dating" entered the American language during the Roaring Twenties.
Social rules regarding dating vary considerably according to variables such as country, social class, race, religion, age, sexual orientation and gender.
Behavior patterns are generally unwritten and constantly changing.
Thus, the concept of marriage is changing widely in many countries.
Historically, marriages in most societies were arranged by parents and older relatives with the goal not being love but legacy and "economic stability and political alliances", according to anthropologists.
