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.
In psychology, libido is psychic drive or energy, usually conceived as sexual in nature, but sometimes conceived as including other forms of desire. The term libido was originally used by the neurologist and pioneering psychoanalyst Sigmund Freud who began by employing it simply to denote sexual desire. Over time it came to signify the psychic energy of the sexual drive, and became a vital concept in psychoanalytic theory. Freud's later conception was broadened to include the fundamental energy of all expressions of love, pleasure, and self-preservation.
Asexuality is the lack of sexual attraction to others, or low or absent interest in or desire for sexual activity. It may be considered a sexual orientation or the lack thereof. It may also be categorized more widely, to include a broad spectrum of asexual sub-identities.
In sexuality, seduction means enticing to sexual intercourse.
Romance or romantic love is a feeling of love for, or a strong attraction towards another person, and the courtship behaviors undertaken by an individual to express those overall feelings and resultant emotions.
Medical fetishism refers to several sexual fetishes in which participants derive sexual pleasure from medical scenarios including objects, practices, environments, and situations of a medical or clinical nature. In sexual roleplay, a hospital or medical scene involves the sex partners assuming the roles of doctors, nurses, surgeons and patients to act out specific or general medical fetishes. Medical fantasy is a genre in pornography, though the fantasy may not necessarily involve pornography or sexual activity.
Heteroflexibility is a form of a sexual orientation or situational sexual behavior characterized by minimal homosexual activity in an otherwise primarily heterosexual orientation, which may or may not distinguish it from bisexuality. It has been characterized as "mostly straight". Although sometimes equated with bi-curiosity to describe a broad continuum of sexual orientation between heterosexuality and bisexuality, other authors distinguish heteroflexibility as lacking the "wish to experiment with ... sexuality" implied by the bi-curious label. The corresponding situation in which homosexual activity predominates has also been described, termed homoflexibility.
Virtual sex is sexual activity where two or more people gather together via some form of communications equipment to arouse each other, often by the means of transmitting sexually explicit messages. Virtual sex describes the phenomenon, no matter the communications equipment used.
Subtext is any content of a creative work which is not announced explicitly but is implicit, or becomes something understood by the audience. Subtext has been used historically to imply controversial subjects without drawing the attention of censors. This has been especially true in comedy; it is also common in science fiction, where it can be easier—and/or safer—to deliver a social critique if, e.g., set in a time other than the (author's) present.
A scene is a dramatic part of a story, at a specific time and place, between specific characters. The term is used in both filmmaking and theatre, with some distinctions between the two.
A cross-sex friendship is a platonic relationship between two unrelated people of differing sexes or gender. There are multiple types of cross-sex friendships, all defined by whether or not each party has a romantic attraction to each other, or perceives that the other is interested. A few theories have been developed to explain the existence of such friendships. Research has been done on why men and women initiate these relationships, how they are perceived by others, implications for children with cross-sex friendships, among others. Cross-sex friendships can also create problems for those involved if either or both have or ever had any romantic feelings for the other.
In psychology, an affectional bond is a type of attachment behavior one individual has for another individual, typically a caregiver for her or his child, in which the two partners tend to remain in proximity to one another. The term was coined and subsequently developed over the course of four decades, from the early 1940s to the late 1970s, by psychologist John Bowlby in his work on attachment theory. The core of the term affectional bond, according to Bowlby, is the attraction one individual has for another individual. The central features of the concept of affectional bonding can be traced to Bowlby's 1958 paper, "The Nature of the Child's Tie to his Mother".
The term emotional affair describes a type of relationship between people. The term often describes a bond between two people that mimics or matches the closeness and emotional intimacy of a romantic relationship while not being physically consummated. An emotional affair is sometimes referred to as an affair of the heart. An emotional affair may emerge from a friendship, and progress toward greater levels of personal intimacy and attachment.
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 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.
A mixed-orientation marriage is a marriage between partners of differing sexual orientations. The broader term is mixed-orientation relationship, sometimes shortened to MOR or MORE.
Bisexuality is a romantic or sexual attraction or behavior toward both males and females, to more than one gender, or to both people of the same gender and different genders. It may also be defined to include romantic or sexual attraction to people regardless of their sex or gender identity, which is also known as pansexuality.
A first date is the initial meeting during the dating process of two individuals, in which an effort is made to ask about each other, plan a potential relationship, and/or organize some sort of romantic activity. Aims vary between finding a romantic, platonic, or sexual partner for a short period, to finding a long-term spouse. Dating can vary between cultures, lifestyles, religion, gender, and sexual orientation.
Sexual arousal describes the physiological and psychological responses in preparation for sexual intercourse or when exposed to sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls, and vaginal lubrication.
Definitions of sexual desire are broad and understandings of sexual desire are subjective. However, the development of various ways of measuring the construct allows for extensive research to be conducted that facilitates the investigation of influences of sexual desire. Particular differences have been observed between the sexes in terms of understanding sexual desire both with regard to one's own sexual desires, as well as what others desire sexually. These beliefs and understandings all contribute to how people behave and interact with others, particularly in terms of various types of intimate relationships.
Demisexuality is a sexual orientation in which an individual does not experience primary sexual attraction – the type of attraction that is based on immediately observable characteristics such as appearance or smell and is experienced immediately after a first encounter. A demisexual person can only experience secondary sexual attraction – the type of attraction that occurs after the development of an emotional bond. The amount of time that a demisexual individual needs to know another person before developing sexual attraction towards them varies from person to person. Demisexuality is generally categorized on the asexuality spectrum.
