Pre-marital sex is sexual activity practiced by persons who are unmarried. Historically considered taboo in many cultures and considered a sin in numerous religions, it has become more commonly accepted by large portions of populaces in developed countries within the last few decades. 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% disapproval, whilst many people within Western European nations were the most accepting, with Spain, Germany and France having less than 10% disapproval.
Until the 1950s, the term "pre-marital sex" referred to sexual relations between two people prior to marrying each other. During that period, Western societies expected that men and women marry by the age of 21 or 22; as such, there were no considerations that one who had sex would not marry. The term was used instead of fornication, due to the negative connotations of the latter.
The meaning has since shifted, referring to all sexual relations a person has prior to marriage; this removes emphasis on who the relations are with. The definition has a degree of ambiguity. It is not clear whether sex between individuals legally forbidden from marrying, or the sexual relations of one uninterested in marrying could be considered premarital.
Alternative terms for pre-marital sex have been suggested, including non-marital sex (which overlaps with adultery), youthful sex, adolescent sex, and young-adult sex. These terms also suffer from a degree of ambiguity, as the definition of having sex differs from person to person.
In some cultures, for example in many modern-day Western cultures, many people do not hold value in sexual abstinence before marriage.
Historically, at least a significant portion of people have engaged in premarital sex, although the number willing to admit to having done so was not always high. In a study conducted in the United States, 61 percent of men and 12 percent of women born prior to 1910 admitted to having premarital sex; the gender disparity may have been caused by cultural double standards regarding the admission of sexual activity or by men frequenting prostitutes.
Starting in the 1920s, and especially after World War II, premarital sex became more common; this was especially prevalent among women. By the end of the 20th century, between 75 and 80 percent of Americans had vaginal intercourse before the age of 19. This has been attributed to numerous causes, including the increasing median age at marriage and the widespread availability of efficient contraceptives.
According to a 2001 UNICEF survey, in 10 out of 12 developed nations with available data, more than two thirds of young people have had sexual intercourse while still in their teens. In Denmark, Finland, Germany, Iceland, Norway, the United Kingdom and the United States, the proportion is over 80%. In Australia, the United Kingdom and the United States, approximately 25% of 15 year olds and 50% of 17 year olds have had sex. In a 2005 Kaiser Family Foundation study of US teenagers, 29% of teens reported feeling pressure to have sex, 33% of sexually active teens reported "being in a relationship where they felt things were moving too fast sexually", and 24% had "done something sexual they didn’t really want to do". Several polls have indicated peer pressure as a factor in encouraging both girls and boys to have sex.
A majority of Americans have had premarital sex, according to a 2007 article in Public Health Reports. This fact is true for current young adults and also young adults in the late 1950s and early 1960s. Data from the National Survey of Family Growth indicate that in 2002, 77% of Americans had sex by age 20, and of that percent, 75% had premarital sex. In comparison, of women who turned 15 between 1964 and 1993, approximately 91% had premarital sex by age 30. Of women who turned 15 between 1954 and 1963, 82% of them had had premarital sex by age 30. Additionally, when comparing the General Social Survey of 1988-1996 to the one of 2004-2012, researchers found that participants of 2004-2012 did not report more sexual partners since the age of 18, nor more frequent sex or sex partners during the past year than those respondents of the 1988-1996 survey. Furthermore, there appears to be no substantial change in sexual behavior contrasting the earlier era to the current one. However, one of the differences included sexually active respondents of the current era were more likely to report having sex with a casual date or friend than reporting having sex with a spouse or regular partner. From 1943 to 1999, attitudes toward premarital sex changed such that young women’s approval increased from 12% to 73% and from 40% to 79% among young men. People’s feelings of sexual guilt also decreased during this period. Nowadays, less than 25% of people believe premarital sex is “always or almost always” wrong.
Within the United States, a cohort study of young adults in university found men self-report more permissive attitudes about casual sex than women. Another study found university students can be grouped by their ideal relationships - those who express a desire for sex exclusively in a committed partnership have fewer hookups and friends with benefits partners than those categorised as desiring "flexible" relationships and recreational sex.
One 2006 study that analysed the Toledo Adolescent Relationships Study found that more boys report having non-dating sexual partners than girls. Of this sample, a third of boys only have had sex with their romantic partner, another third of boys who have had sex with a partner they are not dating within the past year are believed to wish for the girl to be their girlfriend. Many young adults are more likely to engage in sex with romantic partners than with causal acquaintances or friends with benefits.
One 2011 study surveyed young adults about their emotional reactions after sexual encounters, finding that men reported more positive and fewer negative emotional reactions, and both men and women reported that the experience was largely more positive than negative. Women reported that condom use was associated with fewer positive and more negative emotional reactions, and for men condom use was associated with fewer negative emotional reactions. A 23-year study in a Human Sexuality class investigated gender differences in men and women’s reactions to their first sexual experience. In the earlier years of the study, men reported more pleasure and greater anxiety than women, while women reported more feelings of guilt than men. Cohort studies carried out over 23 years found that in later years, women expressed greater pleasure and less guilt. The differences between emotional reactions among men and women decreased slightly during the 23 years. Such decreases in differences to first sexual intercourse may be a result of the increasing normality of premarital sex in America. An international online sex survey compared responses of residents of 37 countries against World Economic Forum figures for gender equality in those countries, finding that countries with high gender equality had respondents report more casual sex, a greater number of sex partners, younger ages for first sex, and greater tolerance of premarital sex.
Different ethnicities and cultures have varied religiosity and sexual attitudes in America. Researchers conducted a study with college participants and they found Asians had more conservative sexual attitudes compared to Hispanics and Euro-Americans. Hispanics reported sexual attitudes similar to that of Euro-Americans. Asian, Hispanic, and Euro-American women with high levels of spirituality were found to have a correlation between conservative sexual attitudes and perceived religiosity. Religiosity and religious fundamentalism predicted conservative sexual attitudes most strongly in Euro-Americans and Asians.
Safe sex practices
People who have premarital sex are recommended by health professionals to take precautions to protect themselves against sexually transmitted infections (STIs) such as HIV/AIDS. There is also a risk of an unplanned pregnancy in heterosexual relationships. Around the world, sex education programs are run to teach school students about reproductive health, safer sex practices, sexual abstinence and birth control.
Sexual activity among unmarried people who do not have access to information about reproductive health and birth control can increase the rate of teenage pregnancies and contraction of sexually transmitted infections. The rates of teenage pregnancy vary and range from 143 per 1000 girls in some sub-Saharan African countries to 2.9 per 1000 in South Korea. The rate for the United States is 52.1 per 1000, the highest in the developed world – and about four times the European Union average. The teenage pregnancy rates between countries must take into account the level of general sex education available and access to contraceptive options.
The cultural acceptability of premarital sex varies between individuals, cultures and time periods. Western cultures have traditionally been disapproving of it, on occasions forbidding it. In other cultures, such as the Muria people of Madhya Pradesh, sexuality prior to marriage is accepted and at times expected.
Individual views within a given society can vary greatly, with expectations ranging from total abstinence to frequent casual sex. These views are dependent on the holders' value system, as formed by his or her parents, religion, friends, experiences, and in many cases the media.
Sex before the public marriage ceremony was normal in the Anglican Church until the Hardwicke Marriage Act of 1753, which for the first time required all marriages in England and Wales occur in their parish church. (The law also applied to Catholics, but Jews and Quakers were exempt.) Before its enactment couples lived and slept together after their betrothal or "the spousals", considered a legal marriage. Until the mid-1700s it was normal and acceptable for the bride to be pregnant at the nuptials, the later public ceremony for the marriage. The Marriage Act combined the spousals and nuptials, and by the start of the 19th century social convention prescribed that brides be virgins at marriage. Illegitimacy became more socially discouraged, with first pregnancies outside of marriage declining from 40% to 20% during the Victorian era, but returning to 40% by the start of the 21st century. In Britain in 2014, only 13% of the population found premarital sex unacceptable
During the colonial period, premarital sex was publicly frowned upon but privately condoned to an extent. Unmarried teenagers were often allowed to spend the night in bed together, though some measures such as bundling were sometimes attempted to prevent sexual intercourse. Even though premarital sex was somewhat condoned, having a child outside of wedlock was not. If a pregnancy resulted from premarital sex, the young couple were expected to marry. Marriage and birth records from the late 1700s reveal that between 30 to 40 percent of New England brides were pregnant before marriage.
The growing popularity of the automobile, and corresponding changes in dating practices, caused premarital sex to become more prevalent. Alfred Kinsey found that American women who became sexually mature during the 1920s were much less likely to be virgins at marriage than those who became mature before World War I. A majority of women during the 1920s under the age of 30 were nonetheless virgins at marriage, however, and half of those who were not only had sex with their fiancés. A 1938 survey of American college students found that 52% of men and 24% of women had had sex. 37% of women were virgins but believed sex outside marriage was acceptable. Prior to the middle of the 20th century, sexuality was generally constrained. Sexual interactions between people without plans to marry was considered unacceptable, with betrothal slightly lessening the stigma. However, premarital sex was still frowned upon.
Beginning in the 1950s, as premarital sex became more common, the stigma attached to it lessened for many people. Love began to become enough for a reason to practice sex, instead of marriage or engagement in the eyes of many. By 2000, roughly a third of couples in the United States had lived together prior to marriage. It should be noted, however, that premarital sex was still considered unacceptable by 30% of the population in a 2014 study, while 29% found it acceptable and 36% considered it not a moral issue.  As such, it should not be assumed that any given individual is either for or against premarital sexual relations.
