'''Safe sex''' (also called '''safer sex''') is the practice of [[sexual activity]] in a manner that lowers the risk of [[infection]] with [[sexually transmitted disease]]s (STDs). Conversely, '''unsafe sex''' is the practice of [[sexual intercourse]] or other sexual contact without regard for prevention of STDs.

Although some safe sex practices can be used as [[contraception]], most forms of contraception don't protect against all or any STDs; likewise, some safe sex practices, like partner selection and low risk sex behavior, aren't effective forms of contraception.

Recently, and mainly within [[Canada]] and the [[United States]], the use of the term ''safer sex'' rather than ''safe sex'' has gained greater use by health workers, with the realization the grounds that risk of transmission of sexually transmitted infections in various [[sexual activities]] is a continuum rather than a simple dichotomy between risky and safe. However, in most other countries, including the [[United Kingdom]] and [[Australia]], the term ''safe sex'' is still mostly used by sex educators.

However, some practices, such as [[self-bondage]] and [[autoerotic asphyxia]], are made considerably more dangerous by the absence of people who can intervene if something goes wrong.
Modern technology does permit some activities, such as "[[phone sex]]" and "[[cybersex]]", that allow for partners to engage in sexual activity without being in the same room, eliminating the risks involved with exchanging bodily fluids.

===Partner selection===
⚫
* [[Monogamy]], practiced faithfully, is very safe (as far as STDs are concerned) when all partners are non-infected. However, many monogamous people have been infected with sexually transmitted diseases by partners who are [[sexual infidelity|sexually unfaithful]], have used injection drugs, or were infected by previous sexual partners; the same risks apply to [[polyfidelity|polyfidelitous]] people, who face higher risks depending on how many people are in the polyfidelitous group.
⚫
* For those who are not monogamous, reducing the number of one's sexual partners, particularly anonymous sexual partners, may also reduce one's potential exposure to STDs. Similarly, one may restrict one's sexual contact to a community of trusted individuals - this is the approach taken by some [[pornographic actor]]s and other [[Forms of nonmonogamy|non-monogamous]] people.

Poster for AIDS education campaign in Laos

Safe sex (also called safer sex or protected sex) is the practice of sexual activity in a manner that lowers the risk of infection with sexually transmitted diseases (STDs), conversely, unsafe sex is sexual contact without regard for prevention of STDs. The term unprotected sex is used for anal or vaginal sexual intercourse without a condom[1] (colloquially known as bareback).

Safe sex practices became more prominent in the late 1980s as a result of the AIDS epidemic. Promoting safe sex is now a principal aim of sex education. From the viewpoint of society, safe sex can be regarded as a harm reduction strategy aimed at reducing risks.

There is strong evidence that condom use reduces the risk of transmission of HIV, gonorrhea, chlamydia, and herpes simplex virus in men and women, and the risk of human papillomavirus (HPV) infection in women.[2]

The risk reduction of safe sex is not absolute; "for example, experts estimate that consistent condom use reduces the risk of HIV transmission by about 80 to 90 percent."[2]

Although some safe sex practices can be used as contraception, most forms of contraception don't protect against all or any STDs; likewise, some safe sex practices, like partner selection and low risk sex behavior, aren't effective forms of contraception.

Terminology

Recently, and mainly within Canada and the United States, the use of the term safer sex rather than safe sex has gained greater use by health workers, in order to make it clearer that these practices reduce risk of transmission along a continuum, rather than a simple dichotomy between risky and safe. However, in most other countries, including the United Kingdom and Australia, the term safe sex is still mostly used by sex educators.

Focus on condoms and HIV control

Much attention has focused on controlling HIV, the virus that causes AIDS, through the use of barrier protection for the penis, specially condoms. However, the HIV is a delicate virus, so protections focused on HIV may not protect against other STIs, which can also be transmitted through other areas of the body where the pathogen (virus or bacteria) has higher prevalence and resistance. Thus some sex educators recommend the use of barrier protection for any sexual contact with anal or vaginal cavities, or oral stimulation of those cavities or penis.

Sex by yourself

Known as autoeroticism, solitary sexual activity is relatively safe. Masturbation, the simple act of stimulating one's own genitalia, is safe so long as contact is not made with other people's discharged bodily fluids. However, some practices, such as self-bondage and autoerotic asphyxia, are made considerably more dangerous by the absence of people who can intervene if something goes wrong. Modern technology does permit some activities, such as "phone sex" and "cybersex", that allow for partners to engage in sexual activity without being in the same room, eliminating the risks involved with exchanging bodily fluids.

Partner selection

  • Monogamy, practiced faithfully, is very safe (as far as STDs are concerned) when all partners are non-infected. However, many monogamous people have been infected with sexually transmitted diseases by partners who are sexually unfaithful, have used injection drugs, or were infected by previous sexual partners; the same risks apply to polyfidelitous people, who face higher risks depending on how many people are in the polyfidelitous group.
  • For those who are not monogamous, reducing the number of one's sexual partners, particularly anonymous sexual partners, may also reduce one's potential exposure to STDs. Similarly, one may restrict one's sexual contact to a community of trusted individuals - this is the approach taken by some pornographic actors and other non-monogamous people.
  • When selecting a sexual parter, some characteristics can increase the risks for contracting sexually transmitted diseases.[3] These include: an age discordance of more than five years[3]; having STD in the past year[3]; problems with marijuana or alcohol[3]; having had sex with other people in the past year[3].

Non-penetrative sex

Main article: Non-penetrative sex

A range of sex acts, sometimes called "outercourse", can be enjoyed by lovers with significantly reduced risks of infection and pregnancy. U.S. President Bill Clinton's surgeon general, Dr. Joycelyn Elders, tried to encourage the use of these practices among young people, but her position encountered opposition from a number of outlets, including the White House itself, and resulted in her being fired by President Clinton in December 1994.[4][5][6]

Barrier protection

Various protective devices are used to avoid contact with blood, vaginal fluid, semen or other contaminant agents (like skin, hair and shared objects) during sexual activity. Practice of sexual activity using this devices is called protected sex.

Condom machine
  • Condoms cover the penis during sexual activity. They are most frequently made of latex, but can also be made out of polyurethane. Polyurethane is thought to be a safe material for use in condoms, since it is nonporous and viruses cannot pass through it. However, there is less research on its effectiveness than there is on latex.
  • Female condoms are inserted into the vagina prior to intercourse. They may also be used for anal sex, although they are less effective.[citation needed]
  • A dental dam (originally used in dentistry) is a sheet of latex used for protection when engaging in oral sex. It is typically used as a barrier between the mouth and the vulva during cunnilingus or between the mouth and the anus during anilingus.
  • Medical gloves made out of latex, vinyl, nitrile, or polyurethane may be used as an makeshift dental dam during oral sex, or to protect the hands during sexual stimulation, like in masturbation. Hands may have invisible cuts on them that may admit pathogens or, more usually, serve as vehicle for contamination of other body part or partner.
  • Another way to protect against pathogen transmission is the use of protected or properly cleaned dildos or other sex toys. If a sex toy is to be used in more than one orifice or partner, a condom can be used over it and changed when the toy is moved.

If any latex barrier is being used, oil-based lubrication should not be used, as this can break down the structure of the latex and remove the protection it provides.

Condoms (male or female) may be used to protect against STDs, and used with other forms of contraception to improve contraceptive effectiveness. For example, simultaneously using both the male condom and spermicide (applied separately, not pre-lubricated) is believed to reduce perfect-use pregnancy rates to those seen among implant users.[7] However, two condoms should not be used simultaneously (male condom on top of male condom, or male condom inside female condom), since this increases the chance of condom failure.[8][9]

Proper use of barriers, such as condoms, depends on the cleanness of surfaces of the barrier, care should be taken to avoid contamination of the barrier when handling it and to control contamination from used surfaces of a barrier.

Limitations

While the use of condoms can reduce HIV transmission, it does not do so completely. One study has suggested it might be around by a factor of 85% to 95% and questioned that effectiveness beyond 95% would be unlikely because of slippage, breakage, and incorrect use.[10] It also noted "In practice, inconsistent use may reduce the overall effectiveness of condoms to as low as 60–70%".[10]p. 40.

The risk of the receptive partner acquiring HIV from HIV seropositive partners not wearing condoms is 0.82% and from those wearing condoms is 0.18%, a four- to five-fold reduction.[11] Where the partner's HIV status is unknown, "Estimated per-contact risk of protected receptive anal intercourse with HIV-positive and unknown serostatus partners, including episodes in which condoms failed, was two thirds the risk of unprotected receptive anal intercourse with the comparable set of partners."[11]p. 310.

STD testing

Main article: STD testing
  • If a person is sexually active with a number of partners, or otherwise at high risk for STD, it is important that they get regular sexual health check-ups. Anyone noticing unusual symptoms should get medical advice quickly as HIV is sometimes asymptomatic or symptoms will have a nonspecific nature and can even be misdiagnosed.[12][13]
  • Tests for some STDs may be advisable before starting to have sex with a new partner. Some pathogens are only detectable a while after infection, so it may be necessary to wait a while after stopping sexual contact with a former partner before testing to improve test accuracy.
  • Periodic STD testing has been used to reduce STD infections in Cuba and among pornographic film actors. Cuba implemented a program of mandatory testing and quarantine early in the AIDS epidemic. [14] In the US pornographic film industry in the US, many production companies will not hire actors without tests for Chlamydia, HIV and Gonorrhea that are no more than 30 days old-and tests for other STD's no more than 6 months old. AIM Medical foundation claims that program of testing has reduced the incidence of STD infection to 20% of that of the general population.

Other Precautions

Acknowledging that it is usually impossible to have entirely risk-free sex with another person, proponents of safe sex recommend that some of the following methods be used to minimize the risks of STD transmission and unwanted pregnancy.

  • Immunization against various viral infections that can be transmitted sexually before starting to have sex. For example, HPV vaccine, which protects against the types of human papillomavirus that are the most common causes of cervical cancer, and Hepatitis B vaccine.
  • Soap and water can reduce infectivity of HIV on devices, such as barrier contraceptives[15]. Douching with soap and water should be avoided because it has not been studied and by disrupting the vaginal flora it might increase risk of infection.[15]
  • Communication with one's sexual partner(s) makes for greater safety. Before initiating sexual activities, partners may discuss what activities they will and will not engage in, and what precautions they will take. This can reduce the chance of risky decisions being made "in the heat of passion".
  • Refraining from the use of recreational drugs, including alcohol, before and during sexual activity can protect against associated risks such as lowered inhibitions, decreased immune response, impaired judgment, and loss of consciousness.
  • Male circumcision is acknowledged by the World Health Organization as a preventative measure against HIV transmission from women to men. African studies have found that circumcision can reduce the rate of transmission of HIV to men by up to 60%.[16] Some advocacy groups dispute these findings.[17][18] However, at least in sub-Saharan Africa, condom use is estimated to be much more cost effective.[19]

Ineffective methods

Note that most methods of contraception other than the barrier methods mentioned above are not effective at preventing the spread of STDs. This includes the "rhythm method".

The spermicide Nonoxynol-9 has been claimed to reduce the likelihood of STD transmission. However a recent study by the World Health Organization [20] has shown that Nonoxynol-9 is an irritant and can produce tiny tears in mucous membranes, which may increase the risk of transmission by offering pathogens more easy points of entry into the system. Condoms with Nonoxynol-9 lubricant do not have enough spermicide to increase contraceptive effectiveness and are not to be promoted.[citation needed]

Coitus interruptus (or "pulling out"), in which the penis is removed from the vagina, anus, or mouth before ejaculation, is not safe sex and can result in STD transmission. This is because of the formation of pre-ejaculate, a fluid that oozes from the urethra before actual ejaculation. In opposition to conventional wisdom, some recent studies awaiting confirmation suggest that pre-ejaculate may not contain sperm[citation needed]; it can, however, contain pathogens such as HIV.[21][22]

Anal sex

Unprotected anal sex is a high risk activity regardless of sexual orientation. Research suggests that although gay men are more likely to engage in anal sex, heterosexual couples are more likely not to use condoms when doing so.[23]

Anal sex is a higer risk activity than vaginal, because very thin tissues of anus and rectum can be easily damaged; this includes by the use of anal toys. Even slight injuries can become "open gates" for various bacteria and viruses, including HIV. This implies that anal sex does require some certain safety measures. First of all, any partners who practice anal sex should be aware of the necessity of using a condom. The condom must be put on properly, otherwise it does not provide reliable protection. Users should keep in mind that oil-based lubricants damage latex. For this reason water-based lubricants should be used for anal sex. Those who have allergy to latex should consider use of non-latex condoms, for instance polyurethane condoms that are compatible with both oil-based and water-based lubricants.

Condoms should also be used with sex toys. By putting a condom on the sex toy, the user provides better hygiene and prevents transmission of infections if the sex toy is shared. However, the condom must be replaced when switching between partners. Cleaning of anal sex toys is also a very important matter as many anal sex toys are made of porous materials. Pores retain viruses and bacteria. For this reason users should clean anal toys (plugs, anal vibrators) thoroughly, preferably with use of special sex toy cleaners. Glass sex toys are more preferred for sexual uses because of their non-porous nature and ability to be sterilized between uses.

Abstinence as an alternative to safe sex

One way to avoid the risks associated with sexual contact is to maintain complete sexual abstinence, which minimizes the risk of contracting STDs. Complete sexual abstinence does not guarantee complete protection against STDs, for the following reasons:

  • Non-sexual transmission: STDs may also be transmitted through non-sexual means. HIV may be transmitted through contaminated needles used in tattooing, body piercing, or injections. Medical or dental procedures using contaminated instruments can also spread HIV, while some health-care workers have acquired HIV through occupational exposure to accidental injuries with needles.[24]
  • Non-consensual sex: A person maintaining complete sexual abstinence may be raped or sexually assaulted, during which STDs may be transmitted.

Long term abstinence is difficult to maintain - those intending to be abstinent may not follow through with that intention, thus when studying or advocating abstinence as a form of safer sex, it is important to consider the failure rate in typical use.[25]

Christian promotion of abstinence

Some groups, notably some evangelical Christians and the Roman Catholic Church oppose sex outside marriage, and object to safe-sex education programs because they believe that providing such education promotes promiscuity. Virginity pledges and sexual abstinence education programs are often promoted in lieu of contraceptives and safe-sex education programs. This can place some teenagers at higher risk of unintended pregnancy and STDs, because about 60 percent of teenagers who pledge virginity until marriage do engage in pre-marital sex and are then one-third less likely to use contraceptives than their peers who have received more conventional sex education.[26]
