Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include anal fingering, the use of sex toys, anilingus, pegging, as well as electrostimulation and erotic torture such as figging. Although anal sex most commonly means penile–anal penetration, sources sometimes use anal intercourse to exclusively denote penile–anal penetration, and anal sex to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation.
A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both male and female condoms.
Sexual intercourse is sexual activity involving the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators. These activities involve physical intimacy between two or more people and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.
Safe sex is sexual activity using methods or contraceptive devices to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks.
The diaphragm is a barrier method of birth control. It is moderately effective, with a one-year failure rate of around 12% with typical use. It is placed over the cervix with spermicide before sex and left in place for at least six hours after sex. Fitting by a healthcare provider is generally required.
Nonoxynol-9, sometimes abbreviated as N-9, is an organic compound that is used as a surfactant. It is a member of the nonoxynol family of nonionic surfactants. N-9 and related compounds are ingredients in various cleaning and cosmetic products. It is widely used in contraceptives for its spermicidal properties.
Spermicide is a contraceptive substance that destroys sperm, inserted vaginally prior to intercourse to prevent pregnancy. As a contraceptive, spermicide may be used alone. However, the pregnancy rate experienced by couples using only spermicide is higher than that of couples using other methods. Usually, spermicides are combined with contraceptive barrier methods such as diaphragms, condoms, cervical caps, and sponges. Combined methods are believed to result in lower pregnancy rates than either method alone.
Vaginal lubrication is a naturally produced fluid that lubricates the vagina. Vaginal lubrication is always present, but production increases significantly near ovulation and during sexual arousal in anticipation of sexual intercourse. Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. Without sufficient lubrication, sexual intercourse can be painful. The vaginal lining has no glands, and therefore the vagina must rely on other methods of lubrication. Plasma from vaginal walls due to vascular engorgement is considered to be the chief lubrication source, and the Bartholin's glands, located slightly below and to the left and right of the introitus, also secrete mucus to augment vaginal-wall secretions. Near ovulation, cervical mucus provides additional lubrication.
Personal lubricants are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts or applied to sex toys to reduce friction or to ease penetration. Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. As of 2015, the personal lubricant market was estimated to be worth at least $400 million.
Oral sex, sometimes referred to as oral intercourse, is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth. Cunnilingus is oral sex performed on the vulva while fellatio is oral sex performed on the penis. Anilingus, another form of oral sex, is oral stimulation of the anus.
Genital herpes is a herpes infection of the genitals caused by the herpes simplex virus (HSV). Most people either have no or mild symptoms and thus do not know they are infected. When symptoms do occur, they typically include small blisters that break open to form painful ulcers. Flu-like symptoms, such as fever, aching, or swollen lymph nodes, may also occur. Onset is typically around 4 days after exposure with symptoms lasting up to 4 weeks. Once infected further outbreaks may occur but are generally milder.
There are many methods of birth control that vary in requirements, side effects, and effectiveness. As the technology, education, and awareness about contraception has evolved, new contraception methods have been theorized and put in application. Although no method of birth control is ideal for every user, some methods remain more effective, affordable or intrusive than others. Outlined here are the different types of barrier methods, hormonal methods, various methods including spermicides, emergency contraceptives, and surgical methods and a comparison between them.
Women who have sex with women (WSW) are women who engage in sexual activities with other women, whether they identify themselves as lesbian, bisexual, or heterosexual, or dispense with sexual identification altogether. The term WSW is often used in medical literature to describe such women as a group for clinical study, without needing to consider sexual self-identity.
An internal condom is a barrier device that is used during sexual intercourse as a barrier contraceptive to reduce the probability of pregnancy or a sexually transmitted infection (STI). Meant as an alternative to the condom, it was invented by Danish MD Lasse Hessel and designed to be worn internally by the woman during vaginal sex to prevent exposure to semen or other body fluids. His invention was launched in Europe in 1990 and approved by the FDA for sale in the US in 1993. Its protection against STIs is inferior to that of male condoms. Internal condoms can be used by the receptive partner during anal 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 sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or cuddling. 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.
The history of condoms goes back at least several centuries, and perhaps beyond. For most of their history, condoms have been used both as a method of birth control, and as a protective measure against sexually transmitted infections such as syphilis, gonorrhea, chlamydia, hepatitis B and more recently HIV/AIDS. Condoms have been made from a variety of materials; prior to the 19th century, chemically treated linen and animal tissue are the best documented varieties. Rubber condoms gained popularity in the mid-19th century, and in the early 20th century major advances were made in manufacturing techniques. Prior to the introduction of the combined oral contraceptive pill, condoms were the most popular birth control method in the Western world. In the second half of the 20th century, the low cost of condoms contributed to their importance in family planning programs throughout the developing world. Condoms have also become increasingly important in efforts to fight the AIDS pandemic.
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is spread by sexual activity, especially vaginal intercourse, anal sex, oral sex, or sometimes manual 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.
A conception device is a medical device which is used to assist in the achievement of a pregnancy, often, but not always, by means other than sexual intercourse. This article deals exclusively with conception devices for human reproduction.
