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] |
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] |
Morality
Morality () is the differentiation of intentions, decisions and actions between those that are distinguished as proper (right) and those that are improper (wrong). Morality can be a body of standards or principles derived from a code of conduct from a particular philosophy, religion or culture, or it can derive from a standard that a person believes should be universal. Morality may also be specifically synonymous with "goodness" or "rightness". Moral philosophy includes meta-ethics, which studies abstract issues such as moral ontology and moral epistemology, and normative ethics, which studies more concrete systems of moral decision-making such as deontological ethics and consequentialism. An example of normative ethical philosophy is the Golden Rule, which states: "One should treat others as one would like others to treat oneself." Immorality is the active opposition to morality (i.e. opposition to that which is good or right), while amorality is variously defined as an ...

Fraternal Birth Order And Male Sexual Orientation
Fraternal birth order has been correlated with male sexual orientation, with a significant volume of research finding that the more older brothers a male has from the same mother, the greater the probability he will have a homosexual orientation. Ray Blanchard and Anthony Bogaert first identified the association in the 1990s and named it the fraternal birth order effect. Scientists have attributed the effect to a prenatal biological mechanism, since the association is only present in men with older biological brothers, and not present among men with older step-brothers and adoptive brothers. The mechanism is thought to be a maternal immune response to male fetuses, whereby antibodies neutralize male Y-proteins thought to play a role in sexual differentiation during development. This would leave some regions of the brain associated with sexual orientation in the 'female typical' arrangement – or attracted to men. Biochemical evidence for this hypothesis was identified in 2017, fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Studies
Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in related fields, from biology to psychology. Twin studies are part of the broader methodology used in behavior genetics, which uses all data that are genetically informative – siblings studies, adoption studies, pedigree, etc. These studies have been used to track traits ranging from personal behavior to the presentation of severe mental illnesses such as schizophrenia. Twins are a valuable source for observation because they allow the study of environmental influence and varying genetic makeup: "identical" or monozygotic (MZ) twins share essentially 100% of their genes, which means that most differences between the twins (such as height, susceptibility to boredom, intelligence, depression, etc.) are due to experiences that one tw ...

Gender Nonconformity
Gender variance or gender nonconformity is behavior or gender expression by an individual that does not match masculine or feminine gender norms. A gender-nonconforming person may be variant in their gender identity, being transgender or non-binary, or they may be cisgender. In the case of transgender people, they may be perceived, or perceive themselves as, gender-nonconforming before transitioning, but might not be perceived as such after transitioning. Transgender adults who appear gender-nonconforming after transition are more likely to experience transphobic discrimination. Terminology People who exhibit gender variance may be called ''gender-variant'', ''gender-nonconforming'', ''gender-diverse,'' or ''gender-atypical''. The terms ''gender variance'' and ''gender-variant'' are used by scholars of psychology, psychiatry, anthropology, and gender studies, as well as advocacy groups of gender-variant people themselves. The term ''gender-variant'' is deliberately broad, encompa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birth Control
Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent unwanted pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable. The World Health Organization and Centers for Disease Control and Prevention, United States Centers for Disease Control and Prevention provide guidance on the safety of birth control methods among women with specific medical conditions. The most effective methods of birth control are Sterilization (medicine), sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and contraceptive implant, implantable birth control. This is follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexually Transmitted Infections
Sexually transmitted infections (STIs), also referred to as sexually transmitted diseases (STDs) and the older term venereal diseases, are infections that are spread by sexual activity, especially vaginal intercourse, anal sex, and oral sex. STIs often do not initially cause symptoms, which results in a risk of passing the infection on to others. Symptoms and signs of STIs may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include chlamydia, gonorrhea, and syphilis. Viral STIs include genital herpes, HIV/AIDS, and genital warts. Parasitic STIs include trichomoniasis. STI diagnostic tests are usually easily available in the developed world, but they are often unavailable in the developing world. Some vaccinations may also decrease the risk of certain infections including hepatitis B and some types of HPV. Safe sex practices, such as use of condoms, having a smaller numb ...

Sexually Repressive
Sexual repression is a state in which a person is prevented from expressing their own sexuality. Sexual repression is often linked with feelings of guilt or shame being associated with sexual impulses. Defining characteristics and practices associated with sexual repression vary between societies and different historical periods. The behaviours and attitudes constituting sexual repression differ across cultures, religious communities and moral systems. Sexual repression can largely be categorised as physical, mental or an amalgam of both. Sexual repression is enforced through legislation in certain countries, many of which are located in the Middle East and North Africa region, and South Asia. Common practices associated with the practice include female genital mutilation. Individuals believed to have engaged in behaviours contradicting social, religious or cultural expectations of sexual repression, such as same-sex sexual activity, may be punished through honor killings, per ...

Religion And Sexuality
The views of the various different religions and religious believers regarding human sexuality range widely among and within them, from giving sex and sexuality a rather negative connotation to believing that sex is the highest expression of the divine. Some religions distinguish between human sexual activities that are practised for biological reproduction (sometimes allowed only when in formal marital status and at a certain age) and those practised only for sexual pleasure in evaluating relative morality. Overview Sexual morality has varied greatly over time and between cultures. A society's sexual norms—standards of sexual conduct—can be linked to religious beliefs, or social and environmental conditions, or all of these. Sexuality and reproduction are fundamental elements in human interaction and societies worldwide. Furthermore, "sexual restriction" is one of the universals of culture peculiar to all human societies. Accordingly, most religions have seen a need to a ...

History Of Human Sexuality
The social construction of human sexuality and Human sexual activity, sexual behavior—along with its taboos, regulation, and sociology, social and politics, political impact—has had a profound effect on the various cultures of the world since Prehistory, prehistoric times. The study of the history of human sexuality The work of Swiss jurist Johann Bachofen made a major impact on the study of the history of sexuality. Many authors, notably Lewis Henry Morgan and Friedrich Engels, were influenced by Bachofen, and criticized Bachofen's ideas on the subject, which were almost entirely drawn from a close reading of ancient mythology. In his 1861 book ''Mother Right: An Investigation of the Religious and Juridical Character of Matriarchy in the Ancient World'' Bachofen writes that in the beginning human sexuality was chaotic and promiscuous. This "aphroditic" stage was replaced by a matriarchal "demeteric" stage, which resulted from the mother being the only reliable way of esta ...

Social Learning Theory
Social learning is a theory of learning process social behavior which proposes that new behaviors can be acquired by observing and imitating others. It states that learning is a cognitive process that takes place in a social context and can occur purely through observation or direct instruction, even in the absence of motor reproduction or direct reinforcement. In addition to the observation of behavior, learning also occurs through the observation of rewards and punishments, a process known as vicarious reinforcement. When a particular behavior is rewarded regularly, it will most likely persist; conversely, if a particular behavior is constantly punished, it will most likely desist. The theory expands on traditional behavioral theories, in which behavior is governed solely by reinforcements, by placing emphasis on the important roles of various internal processes in the learning individual. History and theoretical background In the 1941s, B. F. Skinner delivered a series of lect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reproduction Strategies
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce and organisms only pass on 50% of their genes.John Maynard Smith ''The Evolution of Sex'' 1978. Sexual reproduction typically requires the sexual interaction of two speciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
