Premarital sex is sexual activity which is practiced by people before they are married. Premarital sex is considered a sin by a number of religions and also considered a moral issue which is taboo in many cultures. Since the Sexual Revolution of the 1960s, it has become accepted by certain liberal movements, especially in Western countries. A 2014 Pew study on global morality found that premarital sex was considered particularly unacceptable in "Muslim Majority Countries", such as Malaysia, Jordan and Pakistan, each having over 90% disapproval, while people in Western European countries were the most accepting, with Spain, Germany, and France expressing less than 10% disapproval.
