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.
Orgasm or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary muscular contractions in the pelvic region characterized by sexual pleasure. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins.
Sexual intercourse is sexual activity involving the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.
Foreplay is a set of emotionally and physically intimate acts between one or more people meant to create sexual arousal and desire for sexual activity. Although foreplay is typically understood as physical sexual activity, nonphysical activities, such as mental or verbal acts, may in some contexts be foreplay. This is typically the reason why foreplay tends to be an ambiguous term and means different things to different people. It can consist of various sexual practices such as kissing, sexual touching, removing clothes, oral sex, manual sex, sexual games, and role playing.
A sexual fantasy or erotic fantasy is an autoerotic mental image or pattern of thought that stirs a person's sexuality and can create or enhance sexual arousal. A sexual fantasy can be created by the person's imagination or memory, and may be triggered autonomously or by external stimulation such as erotic literature or pornography, a physical object, or sexual attraction to another person. Anything that may give rise to a sexual arousal may also produce a sexual fantasy, and sexual arousal may in turn give rise to fantasies.
Emotional intimacy is an aspect of interpersonal relationships that varies in intensity from one relationship to another and varies from one time to another, much like physical intimacy. Emotional intimacy involves a perception of closeness to another, sharing of personal feelings, and personal validation.
Sexual stimulation is any stimulus that leads to, enhances and maintains sexual arousal, and may lead to orgasm. Although sexual arousal may arise without physical stimulation, achieving orgasm usually requires it.
Sexual dysfunction is difficulty experienced by an individual or partners during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm. The World Health Organization defines sexual dysfunction as a "person's inability to participate in a sexual relationship as they would wish". This definition is broad and is subject to many interpretations. A diagnosis of sexual dysfunction under the DSM-5 requires a person to feel extreme distress and interpersonal strain for a minimum of six months. Sexual dysfunction can have a profound impact on an individual's perceived quality of sexual life. The term sexual disorder may not only refer to physical sexual dysfunction, but to paraphilias as well; this is sometimes termed disorder of sexual preference.
A rape fantasy or a ravishment is a sexual fantasy involving imagining or pretending being coerced or forcefully coercing another into sexual activity. In sexual roleplay, it involves acting out roles of coercive sex. Rape pornography is literature or images associated with rape and sometimes Stockholm syndrome as a means of sexual arousal.
An intimate relationship is an interpersonal relationship that involves emotional or physical closeness between people and may include sexual intimacy and feelings of romance or love. Intimate relationships are interdependent, and the members of the relationship mutually influence each other. The quality and nature of the relationship depends on the interactions between individuals, and is derived from the unique context and history that builds between people over time. Social and legal institutions such as marriage acknowledge and uphold intimate relationships between people. However, intimate relationships are not necessarily monogamous or sexual, and there is wide social and cultural variability in the norms and practices of intimacy between people.
Pillow talk is the relaxed, intimate conversation that can occur between sexual partners after sexual activity, usually accompanied by cuddling, caresses, kissing, and other physical intimacy. It is associated with honesty, sexual afterglow, and bonding, and is distinguished from dirty talk which sometimes forms part of foreplay and of sexual act.
A sexless marriage is a marital union in which little or no sexual activity occurs between the two spouses. The US National Health and Social Life Survey in 1992 found that 2% of married respondents aged 18 to 59 reported no sexual intimacy in the past year. Comparatively 92% of married respondents aged 65 to 80 reported no sexual intimacy in the past year. The definition of a non-sexual marriage is often broadened to include those where sexual intimacy occurs fewer than ten times per year, in which case 20 percent of the couples in the National Health and Social Life Survey would be in the category. Other studies show that 10% or less of the married population below age 50 have not had sex in the past year. In addition less than 20% report having sex a few times per year, or even monthly, under the age 40.
Sensate focus is a sex therapy technique introduced by the Masters and Johnson team. It works by refocusing the participants on their own sensory perceptions and sensuality, instead of goal-oriented behavior focused on the genitals and penetrative sex. Sensate focus has been used to treat problems with body image, erectile dysfunction, orgasm disorders, and lack of sexual arousal.
Sexual activities involving women who have sex with women (WSW), regardless of their sexual orientation or sexual identity, can include oral sex, manual sex, or tribadism.
Pornography has been defined as any material in varying forms, including texts, video, photos or audio that is consumed for sexual satisfaction and arousal of an individual or partnership. Pornography would have varying effects in regard to things such as exposure and consumption. The effects of pornography on individuals or their intimate relationships depend on the type of pornography used and differs from person to person. The consumption of Pornographic material could have both positive and negative outcomes.
Sexual desire discrepancy (SDD) is the difference between one's desired frequency of sexual intercourse and the actual frequency of sexual intercourse within a relationship. Among couples seeking sex therapy, problems of sexual desire are the most commonly reported dysfunctions, yet have historically been the most difficult to treat successfully. Sexual satisfaction in a relationship has a direct relationship with overall relationship satisfaction and relationship well-being. Sexual desire and sexual frequency do not stem from the same domains, sexual desire characterizes an underlying aspect of sexual motivation and is associated with romantic feelings while actual sexual activity and intercourse is associated with the development and advancement of a given relationship. Thus together, sexual desire and sexual frequency can successfully predict the stability of a relationship. While higher individual sexual desire discrepancies among married individuals may undermine overall relationship well-being, higher SDD scores for females may be beneficial for romantic relationships, because those females have high levels of passionate love and attachment to their partner. Studies suggest that women with higher levels of desire relative to that of their partners' may experience fewer relationship adjustment problems than women with lower levels of desire relative to their partners'. Empirical evidence has shown that sexual desire is a factor that heavily influences couple satisfaction and relationship continuity which has been one of the main reasons for the interest in this research domain of human sexuality.
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, 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.
Center for Healthy Sex is a community therapy center in Los Angeles that specializes in the treatment of sexual dysfunction, sexual anorexia, sex addiction, and love addiction. The Center is located on Santa Monica Boulevard near Overland Avenue bordering the neighborhoods of Century City and Westwood.
Even though intimacy has been broadly defined in terms of romantic love and sexual desire, the neuroanatomy of intimacy needs further explanation in order to fully understand their neurological functions in different components within intimate relationships, which are romantic love, lust, attachment, and rejection in love. Also, known functions of the neuroanatomy involved can be applied to observations seen in people who are experiencing any of the stages in intimacy. Research analysis of these systems provide insight on the biological basis of intimacy, but the neurological aspect must be considered as well in areas that require special attention to mitigate issues in intimacy, such as violence against a beloved partner or problems with social bonding.
