The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time.While the term has several meanings, the most frequent usage refers to two or more people exploring whether they are romantically or sexually compatible by participating in dates with the other.
From the standpoint of anthropology and sociology, dating is linked with other institutions such as marriage and the family which have also been changing rapidly and which have been subject to many forces, including advances in technology and medicine.
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 or marriage.
Those were the ages of Ashton Kutcher and Demi Moore when the couple tied the knot last year, making their highly publicized May-December romance official.
But even though their older woman-younger man relationship may be among the world's most visible, it's not that unusual anymore.
