Human Sexuality
Human sexuality is the way people experience and express themselves sexually. This involves biological, psychological, physical, erotic, emotional, social, or spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle. Someone's sexual orientation is their pattern of sexual interest in the opposite or same sex. Physical and emotional aspects of sexuality include bonds between individuals that are expressed through profound feelings or physical manifestations of love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral, ethical, and religious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Intercourse
Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure or reproduction.Sexual intercourse most commonly means penile–vaginal penetration for sexual pleasure or sexual reproduction; dictionary sources state that it especially means this, and scholarly sources over the years agree. See, for example; * * * * * * * * * This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo). 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. Ther ...

Human Sexual Activity
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 (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) 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 (courtship and display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal. Human sexual activity has sociological, cognitive, emotional, behavioural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Sexual Behaviour
Animal sexual behaviour takes many different forms, including within the same species. Common mating or Reproduction, reproductively motivated systems include Monogamous pairing in animals, monogamy, Polygyny in animals, polygyny, Polyandry in nature, polyandry, polygamy and promiscuity. Other sexual behaviour may be reproductively motivated (e.g. Sexual coercion among animals, sex apparently due to duress or coercion and situational sexual behaviour) or Non-reproductive sexual behavior in animals, non-reproductively motivated (e.g. Homosexual behavior in animals, homosexual sexual behaviour, bisexuality, bisexual sexual behaviour, cross-species sex, Paraphilia, sexual arousal from objects or places, Necrophilia in animals, sex with dead animals, etc.). When animal sexual behaviour is reproductively motivated, it is often termed ''mating'' or ''Copulation (zoology), copulation''; for most non-human mammals, mating and copulation occur at Estrous cycle, oestrus (the most ferti ...

Gender Identity
Gender identity is the personal sense of one's own gender. Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent, and consistent with the individual's gender identity. Gender expression typically reflects a person's gender identity, but this is not always the case. While a person may express behaviors, attitudes, and appearances consistent with a particular gender role, such expression may not necessarily reflect their gender identity. The term ''gender identity'' was coined by psychiatry professor Robert J. Stoller in 1964 and popularized by psychologist John Money. In most societies, there is a basic division between gender attributes assigned to males and females, a gender binary to which most people adhere and which includes expectations of masculinity and femininity in all aspects of sex and gender: biological sex, gender identity, and gender expression. Some people do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-penetrative Sex
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration. It generally excludes the penetrative aspects of vaginal, anal, or oral sexual activity, but includes various forms of sexual and non-sexual activity, such as frottage, mutual masturbation, kissing, or cuddling.Se272 anpage 301 for two different definitions of outercourse (first of the pages for no-penetration definition; second of the pages for no-penile-penetration definition). Some forms of non-penetrative sex, particularly when termed ''outercourse,'' include penetrative aspects, such as penetration that may result from forms of fingering or oral sex. People engage in non-penetrative sex for a variety of reasons, including as a form of foreplay or as a primary or preferred sexual act.Sehere onwards anpages 47–49 for views on what constitutes virginity loss and therefore sexual intercourse or other sexual activity; source discusses how gay and lesbian individuals defi ...

Sex Drive
Libido (; colloquial: sex drive) is a person's overall sexual drive or desire for sexual activity. Libido is influenced by biological, psychological, and social factors. Biologically, the sex hormones and associated neurotransmitters that act upon the nucleus accumbens (primarily testosterone and dopamine, respectively) regulate libido in humans. Social factors, such as work and family, and internal psychological factors, such as personality and stress, can affect libido. Libido can also be affected by medical conditions, medications, lifestyle and relationship issues, and age (e.g., puberty). A person who has extremely frequent sexual urges, or a suddenly increased sex drive may be experiencing hypersexuality, while the opposite condition is hyposexuality. In psychoanalytic theory, libido is psychic drive or energy, particularly associated with sexual instinct, but also present in other instinctive desires and drives. A person may have a desire for sex, but not have the opportun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gender
Gender is the range of characteristics pertaining to femininity and masculinity and differentiating between them. Depending on the context, this may include sex-based social structures (i.e. gender roles) and gender identity. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other (boys/men and girls/women);Kevin L. Nadal, ''The SAGE Encyclopedia of Psychology and Gender'' (2017, ), page 401: "Most cultures currently construct their societies based on the understanding of gender binary—the two gender categorizations (male and female). Such societies divide their population based on biological sex assigned to individuals at birth to begin the process of gender socialization." those who are outside these groups may fall under the umbrella term ''non-binary''. Some societies have specific genders besides "man" and "woman", such as the hijras of South Asia; these are often referred to as ''third gende ...

Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such bacteria and archaea. However, some process in bacteria may be considered analogous to sexual reproduction in that they incorporate new genetic information, including bacterial conjugation, transformatio ...

Masculinity
Masculinity (also called manhood or manliness) is a set of attributes, behaviors, and roles associated with men and boys. Masculinity can be theoretically understood as socially constructed, and there is also evidence that some behaviors considered masculine are influenced by both cultural factors and biological factors. To what extent masculinity is biologically or socially influenced is subject to debate. It is distinct from the definition of the biological male sex, as anyone can exhibit masculine traits. Standards of masculinity vary across different cultures and historical periods. Overview Masculine qualities and roles are considered typical of, appropriate for, and expected of boys and men. Standards of manliness or masculinity vary across different cultures, subcultures, ethnic groups and historical periods. Traits traditionally viewed as masculine in Western society include strength, courage, independence, leadership, and assertiveness.Thomas, R. Murray (2001),Fe ...

Sex And Gender Distinction
Though the terms ''sex'' and ''gender'' have been used interchangeably since at least the fourteenth century, in contemporary academic literature they usually have distinct meanings. ''Sex'' generally refers to an organism's biological sex, while ''gender'' usually refers to either social roles based on the sex of a person (gender role) or personal identification of one's own gender based on an internal awareness (gender identity).Prince, Virginia. 2005. "Sex vs. Gender." ''International Journal of Transgenderism''. 8(4). While in ordinary speech, the terms ''sex'' and ''gender'' are often used interchangeably, most contemporary social scientists, behavioral scientists and biologists, many legal systems and government bodies, and intergovernmental agencies such as the WHO make a distinction between gender and sex. In most individuals, the various biological determinants of sex are congruent, and consistent with the individual's gender identity, but in some circumstances, an individ ...

Copulation (zoology)
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many animals that live in water use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates (such as all reptiles, some fish, and most bird Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweig ...s) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while mammals copulate vaginally, and many primitive (biology), basal vertebrates reproduce sexually with external fertilization. In spiders and insects Spiders are often confused with insects, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
