Sexual abstinence or sexual restraint is the practice of refraining from sexual activity for medical, psychological, legal, social, philosophical, moral, religious or other reasons. It is a part of chastity. Celibacy is sexual abstinence generally motivated by factors such as an individual's personal or religious beliefs.The American Heritage Dictionary of the English Language (3d ed. 1992), entries for celibacy and thence abstinence Sexual abstinence before marriage is required by social norms in some societies, or by law in some countries.

While actual abstinence prevents pregnancy and sexually transmitted infections, mere attempts at abstinence have little effect on the risk of either. Access to other forms of birth control, such as emergency birth control, is thus recommended.

History

The ancient world discouraged promiscuity for both health and social reasons. According to Pythagoras (6th century BCE), sex should be practiced in the winter, but not the summer, but was harmful to male health in every season because the loss of semen was dangerous, hard to control, and both physically and spiritually exhausting, but had no effect on females. This idea may have been merged with Zoroastrian ideas of good and evil in a philosophy known as Gnosticism, which influenced Christian and Islamic attitudes to sexual activity. But others stated that the Christian religion's hold on to the ideal of sexual abstinence prior to the appearing of gnosticism and Zoroastrianism and its roots are to be found in the Old Testament (which is the base of the New Testament) in which virginity was required by law and marriage was especially protected (see Deuteronomy chapter 22).

Throughout history, and especially prior to the 20th century, there have been those who have held that sexual abstinence confers numerous health benefits. For males, lack of abstinence was thought to cause a reduction of vitality. In modern times, the argument has been phrased in biological terms, claiming that loss of semen through ejaculation results in a depletion of vital nutrients such as lecithin and phosphorus, which are also found at high levels in the brain. Conservation of the semen allegedly allows it to be reabsorbed back into the bloodstream and aid in the healthy development of the body. The German philosopher Friedrich Nietzsche spoke of the positive physiological effects of abstinence: "The reabsorption of semen by the blood ... perhaps prompts the stimulus of power, the unrest of all forces towards the overcoming of resistances ... The feeling of power has so far mounted highest in abstinent priests and hermits". Before the "sexual revolution" of the 1960s, it was commonly believed by members of the medical profession that numerous mental and physical diseases in men were caused primarily by loss of nutrients through seminal discharge, and that the deliberate conservation of this substance would lead to increased health, vitality, and intellectual prowess. This also applied to masturbation, which was also thought to lead to bedwetting and hairy palms.

Some advantages in favor of sexual abstinence were also claimed by Walter Siegmeister, better known as Dr. Raymond W. Bernard, an early 20th-century American alternative health, esoteric writer, author and mystic, who formed part of the alternative reality subculture. In his essay entitled "Science discovers the physiological value of continence" (1957) he states:"Science discovers the physiological value of continence"

[I]t is clear that there is an important internal physiological relation between the secretions of the sex glands and the central nervous system, that the loss of these secretions, voluntarily or involuntarily, exercises a detrimental effect on the nutrition and vitality of the nerves and brain, while, on the other hand, the conservation of these secretions has a vitalizing effect on the nervous system, a regenerating effect on the endocrine glands [,] and a rejuvenating effect on the organism as a whole.

Historically, there has been a swing from the sexually liberal end of the Industrial Revolution to the chaste values of the early Victorian period. This was then followed by a new puritanism from the late Victorian era to the mid-1900s. This important transformation often colors discussion of sexual behavior in the later 20th century. World War I began a return to sexual freedom and indulgence, but more often than not, the appearance of conforming to the earlier moral values of abstinence before marriage was retained. With the conclusion of World War II, the societal importance of abstinence declined. The advent of the first oral contraceptive pill and widely available antibiotics suppressed many consequences of wide and free sexual behavior, while social morals were also changing. By the 1970s, abandonment of premarital chastity was no longer taboo in the majority of western societies, and the reverse became true. Some cultural groups continued to place a value on the moral purity of an abstainer, but abstinence was caught up in a wider reevaluation of moral values.

During the early 20th century, prominent feminist and birth control advocate Margaret Sanger argued that abstinence from sexual activity led to greater endurance and strength, and was a sign of the best of the species:

Though sex cells are placed in a part of the anatomy for the essential purpose of easily expelling them into the female for the purpose of reproduction, there are other elements in the sexual fluid which are the essence of blood, nerve, brain, and muscle. When redirected into the building and strengthening of these, we find men or women of the greatest endurance and greatest magnetic power. A girl can waste her creative powers by brooding over a love affair to the extent of exhausting her system, with the results not unlike the effects of masturbation and debauchery.

J. D. Unwin was a British ethnologist and social anthropologist at Oxford and Cambridge universities. Unwin wrote several books including Sex and Culture (1934). In Sex and Culture Unwin studied 80 tribes and six known civilizations through 5,000 years of history and found a positive correlation between the cultural achievement of a people and the amount of sexual restraint which they observed. The author finds that the most culturally successful groups always exhibit lifelong monogamous relationships which include sexual abstinence outside of marriage."Any human society is free to choose either to display great energy or to enjoy sexual freedom; the evidence is that it cannot do both for more than one generation." Unwin, J. D. (1934). Sex and Culture, p. 412. According to Unwin, after a nation becomes prosperous it becomes increasingly liberal with regard to sexual morality and as a result loses its cohesion, its impetus and its purpose, ultimately having a negative effect on society: "The whole of human history does not contain a single instance of a group becoming civilized unless it has been absolutely monogamous, nor is there any example of a group retaining its culture after it has adopted less rigorous customs."

Prevalence Sexual abstinence can be categorized in primary sexual abstinence with no sexual experience at all and secondary sexual abstinence with no sexual activity in last months to years. The percentage of population which is sexually abstinent varies by age, gender, culture and socioeconomic status. A 2020 review found among 25- to 45-year-old men between 5% to 33% with primary sexual abstinence and between 1% and 47% with secondary sexual abstinence.

Involuntary sexual abstinence can be found among single persons who cannot find a person to consent to sex with them and among persons in sexless intimate relationships. Sexual abstinence can also be attributed to external factors such as imprisonment.

During fertile period

Sexual abstinence can be practiced during the period in which the woman is fertile.

Before marriage Premarital chastity

In most cultural, ethical, and religious contexts, sex within marriage is not considered to be contrary to notions of chastity. Some religious systems prohibit sexual activities between a person and anyone other than a spouse of that person, as have past legal systems and societal norms. In such contexts, sexual abstinence was prescribed for unmarried individuals for the purpose of chastity. Chastity has been used as a synonym for sexual abstinence, they are similar but with different connotations.

Legal issues In some countries any sexual activity outside marriage is illegal. Such laws are mostly tied to religion and the legal and political traditions within the particular jurisdiction. Laws differ greatly from country to country. In some countries, such as Saudi Arabia, Pakistan, Afghanistan, Iran, Kuwait, Maldives, Morocco, Mauritania, Qatar, Sudan, Yemen, any form of sexual activity outside marriage is illegal.

Violence

In some parts of the world, people suspected of engaging in premarital or same-sex sexual activity can become victims of honor killings committed by their families. Stoning for sexual activity outside marriage is also a punishment in some places.

Long-term abstinence as a lifestyle

Lifelong (or at least long-term) abstinence, often associated with philosophical or religious asceticism, is distinguished from chastity before marriage. Abstinence is often viewed as an act of self-control over the natural desire to have sex. The display of the strength of character allows the abstainer to set an example for those not able to contain their "base urges". At other times, abstinence has been seen as a great social skill practiced by those who refuse to engage with the material and physical world. Some groups and teachers that propose sexual abstinence consider it an essential means to reach a particular intellectual or spiritual condition, or that chastity allows one to achieve a required self-control or self-consciousness.SSRN-The Hermeneutics of Sexual Order by L. Khan

Abstinence in religions

Some religions regard chastity as a virtue expected of faithful adherents. This usually includes abstinence from sex for the unmarried, and fidelity to a marriage partner.

In some religions, some groups of people are expected to remain unmarried and to abstain from sex completely. These groups include monks, nuns, and priests in various sects of Islam, Judaism, Christianity, Hinduism, and Buddhism. Chastity is required of the respective sacerdotal orders. The Shakers, on the other hand, impose chastity in the form of celibacy for all members, even forgoing procreation such as the case with the castration cult.

Christianity

Most Christians teach that sexual intercourse should occur exclusively within marriage, and that sexual abstinence is the norm outside of that. Sex between people not married to each other is either fornication or adultery. But for married couples, Paul of Tarsus wrote that they should not deprive each other, except for a short time for devotion to prayer.1 Corinthians 7.3-5

The Eastern Orthodox Churches and the Oriental Orthodox Churches teach chastity until marriage. But even then, in accordance with the teaching of the Apostle Paul, periods of abstinence are encouraged among married couples. Traditionally, Orthodox spouses abstain from physical relations on Wednesdays (the day Jesus was betrayed), Fridays (the day Jesus was crucified), the eves of Great Feasts and throughout the four fasting periods (Great Lent, Nativity Fast, Apostles' Fast and Dormition Fast). This is to allow believers "to give themselves time for fasting and prayer ()."
