Premarital sex is sexual activity practiced by people who are unmarried. Historically, premarital sex was considered a moral issue which was taboo in many cultures and considered a sin by a number of religions, but since about the 1960s, it has become more widely accepted, especially in Western countries. A 2014 Pew study on global morality found that premarital sex was considered particularly unacceptable in "predominantly Muslim nations", such as Indonesia, Jordan, Pakistan and Egypt, each having over 90 isapproval, while people in Western European countries were the most accepting, with Spain, Germany and France expressing less than 10 isapproval.
