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.
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.
While pair-bonds of varying forms were recognized by most societies as acceptable social arrangements, marriage was reserved for heterosexual pairings and had a transactional nature, where wives were in many cases a form of property being exchanged between father and husband, and who would have to serve the function of reproduction.
Communities exerted pressure on people to form pair-bonds in places such as Europe; in China, society "demanded people get married before having a sexual relationship" and many societies found that some formally recognized bond between a man and a woman was the best way of rearing and educating children as well as helping to avoid conflicts and misunderstandings regarding competition for mates.
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.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.There are considerable differences between social and personal values.Each culture has particular patterns which determine such choices as whether the man asks the woman out, where people might meet, whether kissing is acceptable on a first date, the substance of conversation, who should pay for meals or entertainment, Since dating can be a stressful situation, there is the possibility of humor to try to reduce tensions.In the mid-twentieth century, the advent of birth control as well as safer procedures for abortion changed the equation considerably, and there was less pressure to marry as a means for satisfying sexual urges.
