Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.These people will have dates on a regular basis, and they may or may not be having sexual relations.Information about human sexuality grew, and with it an acceptance of all types of sexual orientations is becoming more common.Today, the institution of dating continues to evolve at a rapid rate with new possibilities and choices opening up particularly through online dating.Humans have been compared to other species in terms of sexual behavior.Neurobiologist Robert Sapolsky constructed a reproductive spectrum with opposite poles being tournament species, in which males compete fiercely for reproductive privileges with females, and pair bond arrangements, in which a male and female will bond for life.It generally happened in that portion of a person's life before the age of marriage, enabled dates to be arranged without face-to-face contact.
From about 1700 a worldwide movement perhaps described as the "empowerment of the individual" took hold, leading towards greater emancipation of women and equality of individuals.
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 transsexual couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate.
Thus, the concept of marriage is changing widely in many countries.
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.
In the twentieth century, dating was sometimes seen as a precursor to marriage but it could also be considered as an end-in-itself, that is, an informal social activity akin to friendship.
