Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone to acts with another person in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners, or personal interactions between individuals. Sexual activity may follow sexual arousal.
Cohabitation is an arrangement where people who are not married, usually couples, live together. They are often involved in a romantic or sexually intimate relationship on a long-term or permanent basis. Such arrangements have become increasingly common in Western countries since the late 20th century, led by changing social views, especially regarding marriage.
Swinging, earlier commonly known as wife-swapping, is a sexual activity in which both singles and partners in a committed relationship sexually engage with others for recreational purposes. Swinging is a form of non-monogamy. People may choose a swinging lifestyle for a variety of reasons. Practitioners cite an increased quality and quantity of sex. Some people may engage in swinging to add variety into their otherwise conventional sex lives or due to their curiosity. Some couples see swinging as a healthy outlet and means to strengthen their relationship. The term "wife swapping" was introduced by the media in the United States during the 1950s to describe this emerging phenomenon. Swinging, or its wider discussion and practice, is regarded by some as arising from the freer attitudes to sexual activity after the sexual revolution of the 1960s, the invention and availability of the contraceptive pill, and the emergence of treatments for many of the sexually transmitted infections that were known at that time. The adoption of safe sex practices became more common in the late 1980s. It is also a recurring theme in pornography.
In human sexuality, a threesome is "a sexual interaction between three people whereby at least one engages in physical sexual behaviour with both the other individuals". While the term threesome typically refers to sexual activity involving three participants, it has at times been used to refer to a long-term domestic relationship, such as polyamory or a ménage à trois.
Infidelity is a violation of a couple's emotional or sexual exclusivity that commonly results in feelings of anger, sexual jealousy, and rivalry.
Open marriage is a form of non-monogamy in which the partners of a dyadic marriage agree that each may engage in extramarital sexual or romantic relationships, without this being regarded by them as infidelity, and consider or establish an open relationship despite the implied monogamy of marriage. There are variant forms of open marriage such as swinging and polyamory, each with the partners having varying levels of input into their spouse's activities.
Premarital sex is sex before marriage. Premarital sex is sex between two people who are not married to each other. 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.
An open relationship is an intimate relationship that is sexually or romantically non-monogamous. An open relationship generally indicates a relationship where there is a primary emotional and intimate relationship between partners, who agree to at least the possibility of sexual or emotional intimacy with other people. The term "open relationship" is sometimes used interchangeably with the term polyamory, but the two concepts are not identical.
Going steady is when two romantic partners agree to an exclusive relationship. Growing in prevalence in the United States after World War II, this pattern became mainstream in high schools and colleges in the 1950s. Its popularity continued through the 1980s, with teenagers beginning to go steady at progressively earlier ages. However, the label "going steady" fell into disuse in the 1970s.
Non-monogamy is an umbrella term that describes a relationship arrangement where one or more partners are not sexually and/or romantically exclusive to each other. Monogamy and non-monogamy are not strictly binary categories, but rather exist on a continuum encompassing various degrees of exclusivity and openness - at one end of this continuum lie strictly monogamous relationships, while at the other end are openly non-exclusive arrangements with numerous nuanced forms of varying degrees of openness in between. Non-monogamous relationships have been practiced across cultures and throughout history, reflecting diverse social norms, legal frameworks, and personal preferences.
Sexual ethics is a branch of philosophy that considers the ethics or morality of sexual behavior. Sexual ethics seeks to understand, evaluate and critique interpersonal relationships and sexual activities from social, cultural, and philosophical perspectives. Some people consider aspects of human sexuality, such as gender identification and sexual orientation, as well as consent, sexual relations and procreation, as giving rise to issues of sexual ethics.
The following outline is provided as an overview of and topical guide to sexual ethics:
Casual dating or a casual relationship is a physical and emotional relationship between two people who may have casual sex or a near-sexual relationship while staying loyal to each other without necessarily demanding or expecting the additional commitments of a more formal romantic relationship. Motives for casual relationships vary. There are significant gender and cultural differences in acceptance of and breadth of casual relationships, as well as in regrets about action/inaction in those relationships.
Cohabitation in the United States is loosely defined as two or more people, in an intimate relationship, who live together and share a common domestic life but are neither joined by marriage nor a civil union.
Although Westernization and globalization have influenced Filipinos who live in the metropolitan areas, the overall culture remains quite conservative in its sexual values. Filipino sexuality is affected by education received by Filipinos from schools, the media, the rise of the internet, religious teachings from their churches or other similar spiritual institutions, legal policies and laws, and the influence of urbanization or urbanized regions in the Philippines. There are provisions and policies in the constitution of the Philippines which promulgates that the sexual act should happen only within the framework of married life between a man and woman, because this personal human expression is solidly connected to the family unit and to society as a whole.
Sexuality in South Korea has been influenced by culture, religion, and westernization. Viewpoints in contemporary society can be viewed as a conflict between the traditional, conservative older generation and the more liberal and 'modern' generation. Due to this conflict, several issues in Korea, including sexual education, homosexuality, and sexual behavior are highly contested.
Hookup culture is one that accepts and encourages casual sex encounters, including one-night stands and other related activity, without necessarily including emotional intimacy, bonding or a committed relationship. It is generally associated with Western late adolescent sexuality and, in particular, United States college culture. The term hookup has an ambiguous definition because it can indicate kissing or any form of physical sexual activity between sexual partners. The term has been widely used in the U.S. since at least 2000. It has also been called nonrelationship sex, or sex without dating.
Fornication is generally consensual sexual intercourse between two people not married to each other. When one or more of the partners having consensual sexual intercourse is married to another person, it is called adultery. John Calvin viewed adultery to be any sexual act that is outside the divine model for sexual intercourse, which includes fornication.
The Middle East, which is commonly known as a region that includes most countries of Southwestern Asia, the Persian Gulf, the Arabian Peninsula, and several North African countries, and are often seen as part of a wider cultural and geopolitical landscape. Majority of the people in these countries participate in Abrahamic religions such as Islam, Christianity, or Judaism, some of which prohibit premarital sex depending on the wide variety of different sects. While dating and premarital sex are looked down upon for religious and social reasons, it is not illegal. In addition, young people rarely learn about sexual health in school, and other sources of information may not be reliable.
Courtship practices in the United States changed gradually throughout its history. The transition from primarily rural colonies to cities and the expansion across the continent with major waves of immigration, accompanied by developments in transportation, communication, education, industrialization, and the economy, contributed to changes over time in the national culture that influenced how young people met, interacted, and married.
