Sexual intercourse or coitus or copulation is principally the insertion and thrusting of the penis into the vagina for sexual pleasure , reproduction , or both. There are different views on what constitutes sexual intercourse or other sexual activity , which can impact on views on sexual health. Various jurisdictions place restrictions on certain sexual acts, such as incest , sexual activity with minors , prostitution , rape , zoophilia , sodomy , premarital and extramarital sex.

Religious beliefs also play a role in personal decisions about sexual intercourse or other sexual activity, such as decisions about virginity , [16] [17] or legal and public policy matters. Religious views on sexuality vary significantly between different religions and sects of the same religion, though there are common themes, such as prohibition of adultery.

Reproductive sexual intercourse between non-human animals is more often called copulation , and sperm may be introduced into the female's reproductive tract in non-vaginal ways among the animals, such as by cloacal copulation. For most non-human mammals , mating and copulation occur at the point of estrus the most fertile period of time in the female's reproductive cycle , which increases the chances of successful impregnation.

Sexual intercourse may be called coitus , copulation , coition , or intercourse the last of which is typically shorthand for sexual intercourse.

Coitus is derived from the Latin word coitio or coire , meaning "a coming together or joining together" or "to go together", and is known under different ancient Latin names for a variety of sexual activities, but usually denotes penile—vaginal penetration.

Although sexual intercourse , sex and "having sex" also most commonly denote penile—vaginal intercourse, [30] sex can be significantly broad in its meaning and may cover any penetrative or non-penetrative sexual activity between two or more people. Vaginal, anal and oral sex are recognized as sexual intercourse more often than other sexual behaviors. Researchers commonly use sexual intercourse to denote penile—vaginal intercourse while using specific words, such as anal sex or oral sex , for other sexual behaviors.

Lerner and Laurence Steinberg state that researchers also "rarely disclose" how they conceptualize sex "or even whether they resolved potential discrepancies" in conceptualizations of sex. 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 , [56] 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, [73] 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, [15] [84] 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, [12] [89] 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 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 Latin cultures, both from southern Europe Portugal, Greece and Romania are noted and 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 , [] [] 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.
