Studies regarding the meaning of sexual intercourse sometimes conflict. While most consider penile—vaginal intercourse to be sex, whether anal or oral intercourse are considered sex is more debatable, with oral sex ranking lowest.

Sexual intercourse or other sexual activity can encompass various sexually stimulating factors physiological stimulation or psychological stimulation , including different sex positions such as the missionary position , the most common human sex position or the use of sex toys.

Non- primate females copulate only when in estrus , [53] but sexual intercourse is possible at any time of the menstrual cycle for women.

During coitus, the partners orient their hips to allow the penis to move back and forth in the vagina to cause friction, typically without fully removing the penis.

In this way, they stimulate themselves and each other, often continuing until orgasm in either or both partners is achieved.

Anal sex involves stimulation of the anus , anal cavity, sphincter valve or rectum ; it most commonly means the insertion of a man's penis into another person's rectum, but may also mean the use of sex toys or fingers to penetrate the anus, or oral sex on the anus anilingus , or pegging.

Oral sex consists of all the sexual activities that involve the use of the mouth and throat to stimulate genitalia or anus.

It is sometimes performed to the exclusion of all other forms of sexual activity, and may include the ingestion or absorption of semen during fellatio or vaginal fluids during cunnilingus.

Fingering or digital penetration or digital intercourse involves the manual manipulation of the clitoris, rest of the vulva , vagina or anus for the purpose of sexual arousal and sexual stimulation; it may constitute the entire sexual encounter or it may be part of mutual masturbation, foreplay or other sexual activities.

Natural human reproduction involves penile—vaginal penetration, [70] during which semen , containing male gametes known as sperm cells or spermatozoa, is expelled via ejaculation through the penis into the vagina.

The sperm passes through the vaginal vault , cervix and into the uterus , and then into the fallopian tubes. Millions of sperm are present in each ejaculation to increase the chances of fertilization see sperm competition , but only one reaching an egg or ovum is sufficient to achieve fertilization.

When a fertile ovum from the female is present in the fallopian tubes, the male gamete joins with the ovum, resulting in fertilization and the formation of a new embryo.

When a fertilized ovum reaches the uterus, it becomes implanted in the lining of the uterus the endometrium and a pregnancy begins. Pregnancy rates for sexual intercourse are highest during the menstrual cycle time from some 5 days before until 1 to 2 days after ovulation.

When a sperm donor has sexual intercourse with a woman who is not his partner and for the sole purpose of impregnating the woman, this may be known as natural insemination , as opposed to artificial insemination.

Artificial insemination is a form of assisted reproductive technology , which are methods used to achieve pregnancy by artificial or partially artificial means.

For gay male pairings, there is the option of surrogate pregnancy; for lesbian couples, there is donor insemination in addition to choosing surrogate pregnancy.

There are a variety of safe sex methods that are practiced by heterosexual and same-sex couples, including non-penetrative sex acts, [12] [81] and heterosexual couples may use oral or anal sex or both as a means of birth control.

Safe sex is a relevant harm reduction philosophy [86] and condoms are used as a form of safe sex and contraception.

Condoms are widely recommended for the prevention of sexually transmitted infections STIs. Decisions and options concerning birth control can be affected by cultural reasons, such as religion, gender roles or folklore.

Penile—vaginal penetration is the most common form of sexual intercourse. Bruess et al. Regarding oral or anal intercourse, the CDC stated in , "Studies indicate that oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents.

The study said that fewer women reported engaging in anal sex than other partnered sexual behaviors. The prevalence of sexual intercourse has been compared cross-culturally.

In the second group, the data indicated families encouraged daughters to delay marriage, and to abstain from sexual activity before that time.

However, sons are encouraged to gain experience with older women or prostitutes before marriage. Age of men at sexual initiation in these societies is at lower ages than that of women; this group includes south European and Latin cultures Portugal, Greece and Romania are noted and such from Latin America Brazil, Chile , and the Dominican Republic.

The study considered many Asian societies to also fall into this group, although matching data was only available from Thailand.

In the third group, age of men and women at sexual initiation was more closely matched; there were two sub-groups, however. In non-Latin, Catholic countries Poland and Lithuania are mentioned , age at sexual initiation was higher, suggesting later marriage and reciprocal valuing of male and female virginity.

The same pattern of late marriage and reciprocal valuing of virginity was reflected in Singapore and Sri Lanka. The study considered China and Vietnam to also fall into this group, though data were not available.

Concerning United States data, tabulations by the National Center for Health Statistics report that the age of first sexual intercourse was In humans, sexual intercourse and sexual activity in general have been reported as having health benefits as varied as increased immunity by increasing the body's production of antibodies and subsequent lower blood pressure , [99] [] and decreased risk of prostate cancer.

Sexually transmitted infections STIs are bacteria , viruses or parasites that are spread by sexual contact, especially vaginal, anal, or oral intercourse, or unprotected sex.

There are 19 million new cases of sexually transmitted infections every year in the U. Of the 2. The World Health Organization also stated that the "estimated 1.

In cases where infection is suspected, early medical intervention is highly beneficial in all cases. They added that "several co-factors may increase the risk of HIV transmission through oral sex"; this includes ulcers, bleeding gums , genital sores, and the presence of other STIs.

In , the World Health Organization estimated that million women become pregnant worldwide each year, and around 87 million of those pregnancies or Approximately 46 million pregnancies per year reportedly end in induced abortion.

However, many more women become pregnant and miscarry without even realizing it, instead mistaking the miscarriage for an unusually heavy menstruation.

This data includes live births, abortions, and fetal losses. It has been linked to atypical levels of dopamine, a neurotransmitter.

This behavior is characterized by a fixation on sexual intercourse and disinhibition. It was proposed that this 'addictive behavior' be classified in DSM-5 as an impulsive—compulsive behavioral disorder.

Addiction to sexual intercourse is thought to be genetically linked. Those having an addiction to sexual intercourse have a higher response to visual sexual cues in the brain.

Those seeking treatment will typically see a physician for pharmacological management and therapy. It is manifested by hypersomnia and hypersexuality and remains relatively rare.

Sexual activity can directly cause death , particularly due to coronary circulation complications, which is sometimes called coital death, coital sudden death or coital coronary.

Sexual intercourse, when involving a male participant, often ends when the male has ejaculated, and thus the partner might not have time to reach orgasm.

In , scholars from the Kinsey Institute stated, "The truth is that the time between penetration and ejaculation varies not only from man to man, but from one time to the next for the same man.

But he didn't ask if the men or their partners considered two minutes mutually satisfying" and "more recent research reports slightly longer times for intercourse".

Anorgasmia is regular difficulty reaching orgasm after ample sexual stimulation, causing personal distress. Vaginismus is involuntary tensing of the pelvic floor musculature, making coitus, or any form of penetration of the vagina, distressing, painful and sometimes impossible for women.

It is a conditioned reflex of the pubococcygeus muscle, and is sometimes referred to as the PC muscle. Vaginismus can be hard to overcome because if a woman expects to experience pain during sexual intercourse, this can cause a muscle spasm, which results in painful sexual intercourse.

For those whose impotence is caused by medical conditions, prescription drugs such as Viagra , Cialis , and Levitra are available. However, doctors caution against the unnecessary use of these drugs because they are accompanied by serious risks such as increased chance of heart attack.

Sexual intercourse remains possible after major medical treatment of the reproductive organs and structures. This is especially true for women. Even after extensive gynecological surgical procedures such as hysterectomy , oophorectomy , salpingectomy , dilation and curettage , hymenotomy , Bartholin gland surgery, abscess removal, vestibulectomy , labia minora reduction, cervical conization , surgical and radiological cancer treatments and chemotherapy , coitus can continue.

Reconstructive surgery remains an option for women who have experienced benign and malignant conditions.

Obstacles that those with disabilities face with regard to engaging in sexual intercourse include pain, depression , fatigue, negative body image , stiffness, functional impairment, anxiety, reduced libido , hormonal imbalance, and drug treatment or side effects.

Sexual functioning has been regularly identified as a neglected area of the quality of life in patients with rheumatoid arthritis.

The mentally disabled also are subject to challenges in participating in sexual intercourse. Women with Intellectual disabilities ID are often presented with situations that prevent sexual intercourse.

This can include the lack of a knowledgeable healthcare provider trained and experienced in counseling those with ID on sexual intercourse.

Those with ID may have hesitations regarding the discussion of the topic of sex, a lack of sexual knowledge and limited opportunities for sex education.

In addition there are other barriers such as a higher prevalence of sexual abuse and assault. These crimes often remain underreported. There remains a lack of "dialogue around this population's human right to consensual sexual expression, undertreatment of menstrual disorders, and legal and systemic barriers".

Women with ID may lack sexual health care and sex education. They may not recognize sexual abuse. Consensual sexual intercourse is not always an option for some.

Those with ID may have limited knowledge and access to contraception, screening for sexually transmitted infections and cervical cancer. Sexual intercourse may be for reproductive, relational, or recreational purposes.

In humans and bonobos , the female undergoes relatively concealed ovulation so that male and female partners commonly do not know whether she is fertile at any given moment.

One possible reason for this distinct biological feature may be formation of strong emotional bonds between sexual partners important for social interactions and, in the case of humans, long-term partnership rather than immediate sexual reproduction.

Sexual dissatisfaction due to the lack of sexual intercourse is associated with increased risk of divorce and relationship dissolution, especially for men.

For women, there is often a complaint about the lack of their spouses' sexual spontaneity. Decreased sexual activity among these women may be the result of their perceived failure to maintain ideal physical attractiveness or because their sexual partners' health issues have hindered sexual intercourse.

Research additionally indicates that non-married couples who are cohabiting engage in sexual intercourse more often than married couples, and are more likely to participate in sexual activity outside of their sexual relationships; this may be due to the " honeymoon " effect the newness or novelty of sexual intercourse with the partner , since sexual intercourse is usually practiced less the longer a couple is married, with couples engaging in sexual intercourse or other sexual activity once or twice a week, or approximately six to seven times a month.

Adolescents commonly use sexual intercourse for relational and recreational purposes, which may negatively or positively impact their lives. For example, while teenage pregnancy may be welcomed in some cultures, it is also commonly disparaged, and research suggests that the earlier onset of puberty for children puts pressure on children and teenagers to act like adults before they are emotionally or cognitively ready.

Some studies from the s through s suggested an association between self-esteem and sexual intercourse among adolescents, [] while other studies, from the s and s, reported that the research generally indicates little or no relationship between self-esteem and sexual activity among adolescents.

Psychiatrist Lynn Ponton wrote, "All adolescents have sex lives, whether they are sexually active with others, with themselves, or seemingly not at all", and that viewing adolescent sexuality as a potentially positive experience, rather than as something inherently dangerous, may help young people develop healthier patterns and make more positive choices regarding sexual activity.

High-quality romantic relationships are associated with higher commitment in early adulthood, [] and are positively associated with social competence.

While sexual intercourse, as coitus, is the natural mode of reproduction for the human species, humans have intricate moral and ethical guidelines which regulate the practice of sexual intercourse and vary according to religious and governmental laws.

Some governments and religions also have strict designations of "appropriate" and "inappropriate" sexual behavior, which include restrictions on the types of sex acts which are permissible.

A historically prohibited or regulated sex act is anal sex. Sexual intercourse with a person against their will, or without their consent , is rape , but may also be called sexual assault ; it is considered a serious crime in most countries.

Most countries have age of consent laws which set the minimum legal age with whom an older person may engage in sexual intercourse, usually set at 16 to 18, but ranges from 12 to 20, years of age.

In some societies, an age of consent is set by non-statutory custom or tradition. Some countries treat any sex with a person of diminished or insufficient mental capacity to give consent, regardless of age, as rape.

Robert Francoeur et al. Kalbfleisch and Michael J. Over time, the meaning of rape broadened in some parts of the world to include many types of sexual penetration, including anal intercourse, fellatio, cunnilingus, and penetration of the genitals or rectum by an inanimate object.

In , they changed the meaning from "The carnal knowledge of a female forcibly and against her will" to "The penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim.

In most societies around the world, the concept of incest exists and is criminalized. James Roffee, a senior lecturer in criminology at Monash University , [] addressed potential harm associated with familial sexual activity, such as resulting children born with deficiencies.

However, the law is more concerned with protecting the rights of people who are potentially subjected to such abuse. This is why familial sexual relationships are criminalized, even if all parties are consensual.

There are laws prohibiting all kinds of sexual activity between relatives, not necessarily penetrative sex.

These laws refer to grandparents, parents, children, siblings, aunts and uncles. There are differences between states in terms of the severity of punishments and what they consider to be a relative, including biological parents, step-parents, adoptive parents and half-siblings.

Another sexual matter concerning consent is zoophilia , which is a paraphilia involving sexual activity between human and non-human animals, or a fixation on such practice.

Sexual intercourse has traditionally been considered an essential part of a marriage, with many religious customs requiring consummation of the marriage and citing marriage as the most appropriate union for sexual reproduction procreation.

Sexual relations between marriage partners have been a "marital right" in various societies and religions, both historically and in modern times, especially with regard to a husband's rights to his wife.

Adultery engaging in sexual intercourse with someone other than one's spouse has been, and remains, a criminal offense in some jurisdictions.

With regard to divorce laws , the refusal to engage in sexual intercourse with one's spouse may give rise to a grounds for divorce , which may be listed under "grounds of abandonment".

Dwyer stated that no-fault divorce laws "have made it much easier for a woman to exit a marital relationship, and wives have obtained greater control over their bodies while in a marriage" because of legislative and judicial changes regarding the concept of a marital exemption when a man rapes his wife.

There are various legal positions regarding the meaning and legality of sexual intercourse between persons of the same sex or gender.

Blanchflower , it was held that female same-sex sexual relations, and same-sex sexual practices in general, did not constitute sexual intercourse, based on a entry in Webster's Third New International Dictionary that categorizes sexual intercourse as coitus; and thereby an accused wife in a divorce case was found not guilty of adultery.

Opposition to same-sex marriage is largely based on the belief that sexual intercourse and sexual orientation should be of a heterosexual nature.

A related issue is whether the word marriage should be applied. There are wide differences in religious views with regard to sexual intercourse in or outside of marriage:.

In some cases, the sexual intercourse between two people is seen as counter to religious law or doctrine. In many religious communities, including the Catholic Church and Mahayana Buddhists , religious leaders are expected to refrain from sexual intercourse in order to devote their full attention, energy, and loyalty to their religious duties.

In zoology , copulation often means the process in which a male introduces sperm into the female's body, especially directly into her reproductive tract.

Before mating and copulation, the male spider spins a small web and ejaculates on to it. He then stores the sperm in reservoirs on his large pedipalps , from which he transfers sperm to the female's genitals.

The females can store sperm indefinitely. 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 reptiles , some fish , and most birds occur via cloacal copulation see also hemipenis , while mammals copulate vaginally, and many basal vertebrates reproduce sexually with external fertilization.

For primitive insects , the male deposits spermatozoa on the substrate, sometimes stored within a special structure; courtship involves inducing the female to take up the sperm package into her genital opening, but there is no actual copulation.

In dragonflies, it is a set of modified sternites on the second abdominal segment. Bonobos, chimpanzees and dolphins are species known to engage in heterosexual behaviors even when the female is not in estrus, which is a point in her reproductive cycle suitable for successful impregnation.

These species are also known to engage in same-sex sexual behaviors. From Wikipedia, the free encyclopedia. Redirected from Vaginal penetration.
