The sexual revolution, also known as a time of sexual liberation, was a social movement that challenged traditional codes of behavior related to sexuality and interpersonal relationships throughout the United States and the developed world from the 1960s to the 1980s. Sexual liberation included increased acceptance of sex outside of traditional heterosexual, monogamous relationships. The normalization of contraception and the pill, public nudity, pornography, premarital sex, homosexuality, masturbation, alternative forms of sexuality, and the legalization of abortion all followed.

Despite a wide variation in the restrictions under which it is permitted, abortion is legal in most European countries. 95% of European women of reproductive age live in countries which allow abortion on demand or for broad socioeconomic reasons. The exceptions are the mini-state of Malta and the micro-states of Vatican City, Liechtenstein and Andorra, and the large state of Poland, where abortion is illegal or severely restricted. The other state with existent, but less severe restrictions is Monaco. Abortion was also criminalised in San Marino, but a referendum on 26 September 2021 legalised abortion for women up until the twelfth week of pregnancy.

Abortion laws vary widely among countries and have changed over time. Such laws range from abortion being freely available on request, to regulation or restrictions of various kinds, to outright prohibition in all circumstances. Many countries that allow abortion have gestational limits for the procedure depending on the reason; with the majority being up to 12 weeks for abortion on request, up to 24 weeks for rape, incest, or socioeconomic reasons, and more for fetal impairment or threats to the woman's health or life.

Abortion-rights movements, also referred to as pro-choice movements, advocate for legal access to induced abortion services including elective abortion. It is the argument against the pro-life movement. The Abortion rights movement seeks out to represent and support women who wish to terminate their pregnancy at any point. This movement attempts to establish a right for women to make the choice to have an abortion without fear of legal and/or social backlash. The issue of induced abortion remains divisive in public life, with recurring arguments to liberalize or to restrict access to legal abortion services. Abortion-rights supporters themselves are divided as to the types of abortion services that should be available and to the circumstances, for example different periods in the pregnancy such as late term abortions, in which access may be restricted.

Black Bear Ranch is an 80-acre intentional community located in Siskiyou County, California, about 25 miles from Forks of Salmon. It was founded in 1968, with the watchword "free land for free people". It has been considered by some participants and commentators to be one of the more radical examples of communal living/intentional communities that grew out of the counterculture of the 1960s.

The combined oral contraceptive pill (COCP), often referred to as the birth control pill or colloquially as "the pill", is a type of birth control that is designed to be taken orally by women. It includes a combination of an estrogen and a progestogen. When taken correctly, it alters the menstrual cycle to eliminate ovulation and prevent pregnancy.

Deep Throat is a 1972 American pornographic film that was at the forefront of the Golden Age of Porn (1969–1984). The film was written and directed by Gerard Damiano, who was listed in the credits as "Jerry Gerard"; produced by Louis Peraino, credited as "Lou Perry"; and starring Linda Lovelace, the pseudonym given to Linda Susan Boreman.

The Devil in Miss Jones is a 1973 pornographic film, written, directed and produced by Gerard Damiano and starring Georgina Spelvin and Harry Reems. It is widely regarded as a classic adult film, released during the Golden Age of Porn (1969–1984). After his 1972 success with Deep Throat, Damiano shot the film in a converted apple-packing plant in Milanville, Pennsylvania. Along with Deep Throat and Behind the Green Door, the film is associated with a time in American culture known as "porno chic", in which adult erotic films were just beginning to be widely released, publicly discussed by celebrities and taken seriously by film critics. The film's plot was inspired by the 1944 play No Exit by French philosopher Jean-Paul Sartre. The Devil in Miss Jones went on to spawn numerous remakes and sequels.

Free love is a social movement that accepts all forms of love. The movement's initial goal was to separate the state from sexual matters such as marriage, birth control, and adultery. It stated that such issues were the concern of the people involved, and no one else. The movement began around the 19th century, but was notably progressed by the hippies in the Sixties.

The gay liberation movement is a social and political movement of the late 1960s through the mid-1980s that urged lesbians and gay men to engage in radical direct action, and to counter societal shame with gay pride. In the feminist spirit of the personal being political, the most basic form of activism was an emphasis on coming out to family, friends, and colleagues, and living life as an openly lesbian or gay person.

Hair: The American Tribal Love-Rock Musical is a rock musical with a book and lyrics by Gerome Ragni and James Rado and music by Galt MacDermot. The work reflects the creators' observations of the hippie counterculture and sexual revolution of the late 1960s, and several of its songs became anthems of the anti-Vietnam War peace movement. The musical's profanity, its depiction of the use of illegal drugs, its treatment of sexuality, its irreverence for the American flag, and its nude scene caused much comment and controversy. The musical broke new ground in musical theatre by defining the genre of "rock musical", using a racially integrated cast, and inviting the audience onstage for a "Be-In" finale.

A hippie, also spelled hippy, especially in UK English, was a member of the counterculture of the 1960s, originally a youth movement that began in the United States during the mid-1960s and spread to other countries around the world. The word hippie came from hipster and was used to describe beatniks who moved into New York City's Greenwich Village, San Francisco's Haight-Ashbury district, and Chicago's Old Town community. The term hippie was used in print by San Francisco writer Michael Fallon, helping popularise use of the term in the media, although the tag was seen elsewhere earlier.

It shows explicit views of the female genitalia, becoming one of the first major US-based magazines to do so, in contrast with relatively modest publications like Playboy.
