The hormone is also released in women when they give birth or are breastfeeding. Prolactin and oxytocin are responsible for inducing milk production in women. Follicle-stimulating hormone (FSH) is responsible for ovulation in women, which acts by triggering egg maturity; in men it stimulates sperm production. Luteinizing hormone (LH) triggers ovulation, which is the release of a mature egg.
Male anatomy and reproductive system
Males have both internal and external genitalia that are responsible for procreation and sexual intercourse. Production of spermatozoa (sperm

The two bodies that lie side by side in the upper portion of the penis are the corpora cavernosa (cavernous bodies). The third, called the corpus spongiosum (spongy body), is a tube that lies centrally beneath the others and expands at the end to form the tip of the penis (glans).
The raised rim at the border of the shaft and glans is called the corona. The urethra connects the urinary bladder to the penis where urine exits the penis through the urethral meatus

The prostate gland and the seminal vesicles produce seminal fluid that is mixed with sperm to create semen. The prostate gland lies under the bladder and in front of the rectum. It consists of two main zones: the inner zone that produces secretions to keep the lining of the male urethra moist and the outer zone that produces seminal fluids to facilitate the passage of semen. The seminal vesicles secrete fructose for sperm activation and mobilization, prostaglandins to cause uterine contractions that aid movement through the uterus, and bases that help neutralize the acidity of the vagina. The Cowper's glands, or bulbourethral glands, are two pea-sized structures beneath the prostate.

The mons veneris, also known as the Mound of Venus, is a soft layer of fatty tissue overlaying the pubic bone. Following puberty, this area grows in size. It has many nerve endings and is sensitive to stimulation.
The labia minora and labia majora are collectively known as the lips. The labia majora are two elongated folds of skin extending from the mons to the perineum. Its outer surface becomes covered with hair after puberty. In between the labia majora are the labia minora, two hairless folds of skin that meet above the clitoris to form the clitoral hood, which is highly sensitive to touch. The labia minora become engorged with blood during sexual stimulation, causing them to swell and turn red.
The labia minora are composed of connective tissues that are richly supplied with blood vessels which cause a pinkish appearance. Near the anus, the labia minora merge with the labia majora. In a sexually unstimulated state, the labia minora protects the vaginal and urethral opening by covering them. At the base of the labia minora are the Bartholin's glands

Other connective tissue, which forms dense strands called suspensory ligaments, extends inward from the skin of the breast to the pectoral tissue to support the weight of the breast. Heredity and the quantity of fatty tissue determine the size of the breasts.
Men typically find female breasts attractive and this holds true for a variety of cultures. In women, stimulation of the nipple seems to result in activation of the brain's genital sensory cortex (the same region of the brain activated by stimulation of the clitoris, vagina, and cervix). This may be why many women find nipple stimulation arousing and why some women are able to orgasm by nipple stimulation alone.[

, the ovum travels down the Fallopian tubes to the uterus. These extend about from both sides of the uterus. Finger-like projections at the ends of the tubes brush the ovaries and receive the ovum once it is released. The ovum then travels for three to four days to the uterus. After sexual intercourse, sperm swim up this funnel from the uterus. The lining of the tube and its secretions sustain the egg and the sperm, encouraging fertilization

. The female reproductive system does not produce the ova; about 60,000 ova are present at birth, only 400 of which will mature during the woman's lifetime.
Ovulation is based on a monthly cycle; the 14th day is the most fertile. On days one to four, menstruation and production of estrogen and progesterone decreases, and the endometrium starts thinning. The endometrium is sloughed off for the next three to six days. Once menstruation ends, the cycle begins again with an FSH surge from the pituitary gland. Days five to thirteen are known as the pre-ovulatory stage. During this stage, the pituitary gland secretes follicle-stimulating hormone (FSH). A negative feedback loop is enacted when estrogen is secreted to inhibit the release of FSH. Estrogen thickens the endometrium of the uterus. A surge of Luteinizing Hormone

On day 14, the LH surge causes a Graafian follicle to surface the ovary. The follicle ruptures and the ripe ovum is expelled into the abdominal cavity. The fallopian tubes pick up the ovum with the fimbria. The cervical mucus changes to aid the movement of sperm. On days 15 to 28—the post-ovulatory stage, the Graafian follicle—now called the corpus luteum

Sexual response cycle
The sexual response cycle is a model that describes the physiological responses that occur during sexual activity. This model was created by William Masters
William Howell Masters (December 27, 1915 – February 16, 2001) was an American gynecologist, best known as the senior member of the Masters and Johnson sexuality research team. Along with his partner Virginia E. Johnson, he pioneered research i ...
and Virginia Johnson. According to Masters and Johnson, the human sexual response cycle consists of four phases; excitement, plateau, orgasm, and resolution, also called the EPOR model. During the excitement phase of the EPOR model, one attains the intrinsic motivation to have sex. The plateau phase is the precursor to orgasm, which may be mostly biological for men and mostly psychological for women. Orgasm is the release of tension, and the resolution period is the unaroused state before the cycle begins again.
The male sexual response cycle starts in the excitement phase; two centers in the spine are responsible for erections. Vasoconstriction in the penis begins, the heart rate increases, the scrotum thickens, the spermatic cord shortens, and the testicles become engorged with blood. In the plateau phase, the penis increases in diameter, the testicles become more engorged, and the Cowper's glands secrete pre-seminal fluid. The orgasm phase, during which rhythmic contractions occur every 0.8 seconds, consists of two phases; the emission phase, in which contractions of the vas deferens, prostate, and seminal vesicles encourage ejaculation, which is the second phase of orgasm. Ejaculation is called the expulsion phase; it cannot be reached without an orgasm. In the resolution phase, the male is now in an unaroused state consisting of a refractory (rest) period before the cycle can begin. This rest period may increase with age.
The female sexual response begins with the excitement phase, which can last from several minutes to several hours. Characteristics of this phase include increased heart and respiratory rate, and an elevation of blood pressure. Flushed skin or blotches of redness may occur on the chest and back; breasts increase slightly in size and nipples may become hardened and erect. The onset of vasocongestion
Vasocongestion, vascular congestion or vascular engorgement is the swelling of bodily tissues caused by increased vascular blood flow and a localized increase in blood pressure. Typical causes of vasocongestion in humans includes menstruation, sexu ...
results in swelling of the clitoris, labia minora, and vagina. The muscle that surrounds the vaginal opening tightens and the uterus elevates and grows in size. The vaginal walls begin to produce a lubricating liquid. The second phase, called the plateau phase, is characterized primarily by the intensification of the changes begun during the excitement phase. The plateau phase extends to the brink of orgasm, which initiates the resolution stage; the reversal of the changes begun during the excitement phase. During the orgasm stage the heart rate, blood pressure, muscle tension, and breathing rates peak. The pelvic muscle near the vagina, the anal sphincter, and the uterus contract. Muscle contractions in the vaginal area create a high level of pleasure, though all orgasms are centered in the clitoris.
Sexual dysfunction and sexual problems
Sexual disorders, according to the DSM-IV-TR, are disturbances in sexual desire and psycho-physiological changes that characterize the sexual response cycle and cause marked distress and interpersonal difficulty. The sexual dysfunctions is a result of physical or psychological disorders. The physical causes include hormonal imbalance, diabetes, heart disease and more. The psychological causes includes but are not limited to stress, anxiety, and depression. The sexual dysfunction affects men and women. There are four major categories of sexual problems for women: desire disorders, arousal disorders, orgasmic disorders, and sexual pain disorders. The sexual desire disorder occurs when an individual lacks the sexual desire because of hormonal changes, depression, and pregnancy. The arousal disorder is a female sexual dysfunction. Arousal disorder means lack of vaginal lubrication. In addition, blood flow problems may affect arousal disorder. Lack of orgasm, also known as, anorgasmia is another sexual dysfunction in women. The anorgasmia occurs in women with psychological disorders such as guilt and anxiety that was caused by sexual assault. The last sexual disorder is the painful intercourse. The sexual disorder can be result of pelvic mass, scar tissue, sexually transmitted disease and more.
There are also three common sexual disorders for men including, sexual desire, ejaculation disorder, and erectile dysfunction. The lack of sexual desire in men is because of loss of libido, low testosterone. There are also psychological factors such as anxiety, and depression.
The ejaculation disorder has three types: retrograde ejaculation, retarded ejaculation, premature ejaculation. The erectile dysfunction is a disability to have and maintain an erection during intercourse.
Psychological aspects
As one form of behavior, the psychological aspects of sexual expression have been studied in the context of emotional involvement, gender identity, intersubjective intimacy, and Darwinian reproductive efficacy. Sexuality in humans generates profound emotional and psychological responses. Some theorists identify sexuality as the central source of human personality. Psychological studies of sexuality focus on psychological influences that affect sexual behavior and experiences. Early psychological analyses were carried out by Sigmund Freud

Heterosexual people are romantically/sexually attracted to the members of the opposite sex, gay and lesbian people are romantically/sexually attracted to people of the same sex, and those who are bisexual are romantically/sexually attracted to both sexes.
The idea that homosexuality results from reversed gender roles is reinforced by the media's portrayal of male homosexuals as effeminate and female homosexuals as masculine. However, a person's conformity or non-conformity to gender stereotypes does not always predict sexual orientation. Society believes that if a man is masculine he is heterosexual, and if a man is feminine he is homosexual. There is no strong evidence that a homosexual or bisexual orientation must be associated with atypical gender roles. By the early 21st century, homosexuality was no longer considered to be a pathology. Theories have linked many factors, including genetic, anatomical, birth order, and hormones in the prenatal environment, to homosexuality.
Other than the need to procreate, there are many other reasons people have sex. According to one study conducted on college students (Meston & Buss, 2007), the four main reasons for sexual activities are; physical attraction, as a means to an end, to increase emotional connection, and to alleviate insecurity.

From birth, the mother's connection to the infant affects the infant's later capacity for pleasure and attachment. Freud described two currents of emotional life; an affectionate current, including our bonds with the important people in our lives; and a sensual current, including our wish to gratify sexual impulses. During adolescence, a young person tries to integrate these two emotional currents.

Sex play with others usually decreases as children grow, but they may later possess romantic interest in their peers. Curiosity levels remain high during these years, but the main surge in sexual interest occurs in adolescence.
Sexuality in late adulthood
Adult sexuality originates in childhood. However, like many other human capacities, sexuality is not fixed, but matures and develops. A common stereotype associated with old people is that they tend to lose interest and the ability to engage in sexual acts once they reach late adulthood. This misconception is reinforced by Western popular culture, which often ridicules older adults who try to engage in sexual activities. Age does not necessarily change the need or desire to be sexually expressive or active. A couple in a long-term relationship may find that the frequency of their sexual activity decreases over time and the type of sexual expression may change, but many couples experience increased intimacy and love.
Sociocultural aspects
Human sexuality can be understood as part of the social life of humans, which is governed by implied rules of behavior and the status quo. This narrows the view to groups within a society.

Sex education
The age and manner in which children are informed of issues of sexuality is a matter of sex education. The school systems in almost all developed countries have some form of sex education, but the nature of the issues covered varies widely. In some countries, such as Australia and much of Europe, age-appropriate sex education often begins in pre-school, whereas other countries leave sex education to the pre-teenage and teenage years. Sex education covers a range of topics, including the physical, mental, and social aspects of sexual behavior. Communities have differing opinions on the appropriate age for children to learn about sexuality. According to ''Time

Proponents for an abstinence-only education believe that teaching a comprehensive curriculum would encourage teenagers to have sex, while proponents for comprehensive sex education argue that many teenagers will have sex regardless and should be equipped with knowledge of how to have sex responsibly. According to data from the National Longitudinal Survey of Youth, many teens who intend to be abstinent fail to do so, and when these teenagers do have sex, many do not use safe sex practices such as contraceptives.
Sexuality in history
Sexuality has been an important, vital part of human existence throughout history. All civilizations have managed sexuality through sexual standards, representations, and behavior.
Before the rise of agriculture, groups of hunter-gatherers and nomadic groups inhabited the world. These groups had less restrictive sexual standards that emphasized sexual pleasure and enjoyment, but with definite rules and constraints. Some underlying continuities or key regulatory standards contended with the tension between recognition of pleasure, interest, and the need to procreate for the sake of social order and economic survival. Hunter-gatherers also placed high value on certain types of sexual symbolism.
A common tension in hunter-gatherer societies is expressed in their art, which emphasized male sexuality and prowess, but also blurred gender lines in sexual matters. One example of these male-dominated portrayals is the Egyptian creation myth

Once agricultural societies emerged, the sexual framework shifted in ways that persisted for many millennia in much of Asia, Africa, Europe, and parts of the Americas. One common characteristic new to these societies was the collective supervision of sexual behavior due to urbanization and the growth of population and population density. Children would commonly witness parents having sex because many families shared the same sleeping quarters. Due to land ownership, determination of children's paternity became important, and society and family life became patriarchal. These changes in sexual ideology were used to control female sexuality and to differentiate standards by gender. With these ideologies, sexual possessiveness and increases in jealousy emerged.
While retaining the precedents of earlier civilizations, each classical civilization established a somewhat distinctive approach to gender, artistic expression of sexual beauty, and to behaviors such as homosexuality. Some of these distinctions are portrayed in sex manuals, which were also common among civilizations in China, Greece, Rome, Persia, and India; each has its own sexual history.

New pornographic industries grew and Japan adopted its first laws against homosexuality. In Western societies, the definition of homosexuality was constantly changing; Western influence on other cultures became more prevalent. New contacts created serious issues around sexuality and sexual traditions. There were also major shifts in sexual behavior. During this period, puberty began occurring at younger ages, so a new focus on adolescence as a time of sexual confusion and danger emerged. There was a new focus on the purpose of marriage; it was increasing regarded as being for love rather than only for economics and reproduction.

and Sigmund Freud adopted more accepting stances toward homosexuality; Ellis said homosexuality was inborn and therefore not immoral, not a disease, and that many homosexuals made significant contributions to society. Freud wrote that all human beings as capable of becoming either heterosexual or homosexual; neither orientation was assumed to be innate. According to Freud, a person's orientation depended on the resolution of the Oedipus complex. He said male homosexuality resulted when a young boy had an authoritarian, rejecting mother and turned to his father for love and affection, and later to men in general. He said female homosexuality developed when a girl loved her mother and identified with her father, and became fixated at that stage.

" category. This system of gender contradicts both the gender binary and the assertion that sex and gender are the same. Instead of conforming to traditional roles of men and women, two-spirit fill a special niche in their communities.
For example, two-spirited people are commonly revered for possessing special wisdom and spiritual powers. Two-spirited people also can take part in marriages, either monogamous and polygamous ones. Historically, European colonizers perceived relationships involving two-spirited people as homosexuality, and therefore believed in the moral inferiority of native people. In reaction, colonizers began to impose their own religious and social norms on indigenous communities, diminishing the role of two-spirit people in native cultures. Within reservations, the Religious Crime Code of the 1880s explicitly aimed to "aggressively attack Native sexual and marriage practices". The goal of colonizers was for native peoples to assimilate into Euro-American ideals of family, sexuality, gender expression, and more.
The link between constructed sexual meanings and racial ideologies has been studied. According to Joane Nagel, sexual meanings are constructed to maintain racial-ethnic-national boundaries by the denigration of "others" and regulation of sexual behavior within the group. She writes, "both adherence to and deviation from such approved behaviors, define and reinforce racial, ethnic, and nationalist regimes". In the United States people of color face the effects of colonialism in different ways with stereotypes such as the Mammy and Jezebel for Black women; lotus blossom and dragon lady for Asian women; and the spicy Latina. These stereotypes contrast with standards of sexual conservatism, creating a dichotomy that dehumanizes and demonizes the stereotyped groups.

Stigma of contraceptives in the U.S.
In 1915, Emma Goldman and Margaret Sanger, leaders of the birth control movement, began to spread information regarding contraception in opposition to the laws, such as the Comstock Law, that demonized it. One of their main purposes was to assert that the birth control movement was about empowering women with personal reproductive and economic freedom for those who could not afford to parent a child or simply did not want one. Goldman and Sanger saw it necessary to educate people as contraceptives were quickly being stigmatized as a population control tactic due to being a policy limiting births, disregarding that this limitation did not target ecological, political, or large economic conditions. This stigma targeted lower-class women who had the most need of access to contraception.
Birth control finally began to lose stigma in 1936 when the ruling of U.S. v. One Package declared that prescribing contraception to save a person's life or well-being was no longer illegal under the Comstock Law. Although opinions varied on when birth control should be available to women, by 1938, there were 347 birth control clinics in the United States but advertising their services remained illegal.
The stigma continued to lose credibility as First Lady Eleanor Roosevelt publicly showed her support for birth control through the four terms her husband served (1933–1945). However, it was not until 1966 that the Federal Government began to fund family planning and subsidized birth control services for lower-class women and families at the order of President Lyndon B. Johnson. This funding continued after 1970 under the Family Planning Services and Population Research Act. Today, all Health Insurance Marketplace plans are required to cover all forms of contraception, including sterilization procedures, as a result of The Affordable Care Act signed by President Barack Obama in 2010.
Stigma and activism during the AIDS epidemic

in America. The disease disproportionately affected and continues to affect gay and bisexual men, especially black and Latino men. The Reagan administration is criticized for its apathy towards the AIDS epidemic, and audio recordings reveal that Ronald Reagan's press secretary Larry Speakes viewed the epidemic as a joke, mocking AIDS by calling it the "gay plague". The epidemic also carried stigma coming from religious influences. For example, Cardinal Krol voiced that AIDS was "an act of vengeance against the sin of homosexuality", which clarifies the specific meaning behind the pope's mention of "the moral source of AIDS."

during the AIDS crisis focused on promoting safe sex practices to raise awareness that the disease could be prevented. The "Safe Sex is Hot Sex" campaign, for example, aimed to promote the use of condoms. Campaigns by the U.S. government, however, diverged from advocacy of safe sex. In 1987, Congress even denied federal funding from awareness campaigns that " romotedor ncouraged directly or indirectly, homosexual activities". Instead, campaigns by the government primarily relied on scare tactics in order to instill fear in men who had sex with other men.
In addition to prevention campaigns, activists also sought to counteract narratives that led to the "social death" for people living with AIDS. Gay men
Gay men are male homosexuals. Some bisexual and homoromantic men may also dually identify as gay, and a number of young gay men also identify as queer. Historically, gay men have been referred to by a number of different terms, including ' ...

In his article "Emergence of Gay Identity and Gay Social Movements in Developing Countries", Matthew Roberts discusses how international AIDS prevention campaigns created opportunities for gay men to interact with other openly gay men from other countries. These interactions allowed western gay "culture" to be introduced to gay men in countries where homosexuality wasn't an important identifier. Thus, group organizers self-identified as gay more and more, creating the basis for further development of gay consciousness in different countries.

and worldwide there are over 340 million sexually transmitted infections each year. More than half of these occur in adolescents and young adults aged 15–24 years. At least one in four US teenage girls has a sexually transmitted disease. In the U.S., about 30% of 15- to 17-year-olds have had sexual intercourse, but only about 80% of 15- to 19-year-olds report using condoms for their first sexual intercourse. In one study, more than 75% of young women age 18–25 years felt they were at low risk of acquiring an STD.
Creating a relationship
People both consciously and subconsciously seek to attract others with whom they can form deep relationships. This may be for companionship, procreation, or an intimate relationship.

There are different types of flirting, and most people usually have one way of flirting that makes them most comfortable. When flirting, people can be polite, playful, physical, etc. Sometimes it is difficult to know whether or not the person is interested. Non-verbal flirting allows people to test another's interest without fear of direct rejection. Flirting styles vary according to culture. Different cultures have different social etiquette. For example, length of eye contact, or how closely one stands by someone.

In the United States, there are two fundamentally different approaches, applied in different states, regarding the way the law is used to attempt to govern a person's sexuality. The "black letter" approach to law focuses on the study of pre-existing legal precedent, and attempts to offer a clear framework of rules within which lawyers and others can work.[ In contrast, the socio-legal approach focuses more broadly on the relationship between the law and society, and offers a more contextualized view of the relationship between legal and social change.][

The gay liberation movement was a social and political movement of the late 1960s through the mid-1980s that urged lesbians and gay men to engage in radical direct action, and to counter societal shame with gay pride.Hoffman, 2007, pp.xi-xiii. ...

" and engage with the legal system, primarily through courts. Therefore, many issues regarding human sexuality and the law are found in the opinions of the courts.
Sexual privacy
While the issue of privacy has been useful to sexual rights claims, some scholars have criticized its usefulness, saying that this perspective is too narrow and restrictive. The law is often slow to intervene in certain forms of coercive behavior that can limit individuals' control over their own sexuality (such as female genital mutilation, forced marriages or lack of access to reproductive health care). Many of these injustices are often perpetuated wholly or in part by private individuals rather than state agents, and as a result, there is an ongoing debate about the extent of state responsibility to prevent harmful practices and to investigate such practices when they do occur.
State intervention with regards to sexuality also occurs, and is considered acceptable by some, in certain instances (e.g. same-sex sexual activity or prostitution
Prostitution is the business or practice of engaging in Sex work, sexual activity in exchange for payment. The definition of "sexual activity" varies, and is often defined as an activity requiring physical contact (e.g., sexual intercourse, n ...
).
The legal systems surrounding prostitution are a topic of debate. Proponents for criminalization argue that sex work is an immoral practice that should not be tolerated, while proponents for decriminalization point out how criminalization does more harm than good. Within the feminist movement, there is also a debate over whether sex work is inherently objectifying and exploitative or whether sex workers have the agency to sell sex as a service.
When sex work is criminalized, sex workers do not have support from law enforcement when they fall victim to violence. In a 2003 survey of street-based sex workers in NYC, 80% said they had been threatened with or experienced violence, and many said the police were no help. 27% said they had experienced violence from police officers themselves. Different identities such as being black, transgender, or poor can result in a person being more likely to be criminally profiled by the police. For example, in New York, there is a law against "loitering for the purpose of engaging in prostitution", which has been nicknamed the "walking while trans" law because of how often transgender women are assumed to be sex workers and arrested for simply walking out in public.
