Safe sex

Safe sex is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Safe sex rather than just read about it. In short: Safe sex is sexual activity using protective methods or contraceptive devices (such as condoms) to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. The terms safer sex and protected sex are sometimes preferred, to indicate that even highly effective prevention practices do not eliminate all possible risks.

Key takeaways

  • Safe sex belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Safe sex to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Safe sex from memory before moving on to harder problems.

Reference excerpt

Safe sex is sexual activity using protective methods or contraceptive devices (such as condoms) to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. The terms safer sex and protected sex are sometimes preferred, to indicate that even highly effective prevention practices do not eliminate all possible risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks. The concept of safe sex emerged in the 1980s as a response to the global AIDS epidemic, and possibly more specifically to the AIDS crisis in the United States. Promoting safe sex is now one of the main aims of sex education and STI prevention, especially reducing new HIV infections. Safe sex is regarded as a harm reduction strategy aimed at reducing the risk of STI transmission. Although some safe sex practices (like condoms) can also be used as birth control (contraception), most forms of contraception do not protect against STIs. Likewise, some safe sex practices, such as partner selection and low-risk sex behavior, might not be effective forms of contraception.

History

Although strategies for avoiding STIs like syphilis and gonorrhea have existed for centuries and the term safe sex existed in English as early as the 1930s, the use of the term to refer to STI-risk reduction dates to the mid-1980s in the United States. It emerged in response to the HIV/AIDS crisis. A year before the HIV virus was isolated and named, the San Francisco chapter of the Sisters of Perpetual Indulgence published a small pamphlet titled Play Fair! out of concern over widespread STIs among the city's gay male population. It specifically named illnesses (Kaposi's sarcoma and pneumocystis pneumonia) that would later be understood as symptoms of advanced HIV disease (AIDS). The pamphlet advocated a range of safe-sex practices, including abstinence, condoms, personal hygiene, use of personal lubricants, and STI testing/treatment. It took a casual, sex-positive approach while also emphasizing personal and social responsibility. In May 1983—the same month HIV was isolated and named in France—the New York City-based HIV/AIDS activists Richard Berkowitz and Michael Callen published similar advice in their booklet, How to Have Sex in an Epidemic: One Approach. Both publications included recommendations that are now standard advice for reducing STI (including HIV) risks.

Safe sex as a form of STI risk reduction appeared in journalism as early as 1984, in the British publication The Daily Intelligencer: "The goal is to reach about 50 million people with messages about safe sex and AIDS education." Although safe sex is used by individuals to refer to protection against both pregnancy and HIV/AIDS or other STI transmissions, the term was born in response to the HIV/AIDS epidemic. It is believed that the term safe sex was used in the professional literature in 1984, in the content of a paper on the psychological effect that HIV/AIDS may have on gay and bisexual men.

A year later, the same term appeared in an article in The New York Times. This article emphasized that most specialists advised their AIDS patients to practice safe sex. The concept included limiting the number of sexual partners, using prophylactics, avoiding bodily fluid exchange, and resisting the use of drugs that reduced inhibitions for high-risk sexual behavior. Moreover, in 1985, the first safe sex guidelines were established by the 'Coalition for Sexual Responsibilities'. According to these guidelines, safe sex was practiced by using condoms also when engaging in anal or oral sex. Although the term safe sex was primarily used in reference to sexual activity between men, in 1986 the concept was spread to the general population. Various programs were developed to promote safe sex practices among college students. These programs were focused on promoting the use of the condom, a better knowledge about the partner's sexual history, and limiting the number of sexual partners. The first book on this subject, Safe Sex in the Age of AIDS, appeared in the same year. It had 88 pages that described both positive and negative approaches to sexual life. Sexual behavior was loosely sorted into safe (kissing, hugging, massage, body-to-body rubbing, mutual masturbation, exhibitionism, phone sex, and use of separate sex toys); possibly safe (use of condoms); or unsafe. In 1997, specialists in this matter promoted the use of condoms as the most accessible safe sex method (besides abstinence), and they called for TV commercials featuring condoms. During the same year, the Catholic Church in the United States issued its own safer sex guidelines on which condoms were listed. Two years later, the Vatican urged chastity and heterosexual marriage, attacking the American Catholic bishops' guidelines. A 2006 survey found that the most common definitions of safe sex are condom use (68% of the interviewed subjects), abstinence (31.1% of the interviewed subjects), monogamy (28.4% of the interviewed subjects), and safe partner (18.7% of the interviewed subjects). The term safer sex in Canada and the United States has gained greater use by health workers, reflecting that risk of transmission of sexually transmitted infections in various sexual activities is a continuum. Safer sex is thought to make it more obvious to individuals that any sexual activity carries a certain degree of risk. The term safe sex is still in common use in the United Kingdom, Australia and New Zealand. The term safe love has also been used, notably by the French Sidaction in the promotion of men's underpants incorporating a condom pocket and including the red ribbon symbol in the design, which were sold to support the charity.

Practices Sexual Health Educators and Public Health Agencies recommend a range of safe-sex practices. Many of these practices can reduce (but not eliminate) risk of transmitting or acquiring STIs.

Phone sex/cybersex/sexting Sexual activities, such as phone sex, cybersex, and sexting, that do not include direct contact with the skin or bodily fluids of sexual partners, carry no STI risks and, thus, are forms of safe sex.

Worked examples

Example 1 — a first encounter with Safe sex

Start with the simplest possible case. Write down what Safe sex claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Safe sex before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Safe sex ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Safe sex

In research
Safe sex appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Safe sex in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Safe sex is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birth control, Harm reduction, Infection-control measures, so understanding it makes those chapters shorter.
In everyday life
Look for Safe sex outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
