Casual sex

Casual sex is sexual activity that takes places outside of a romantic relationship and implies an absence of commitment, emotional attachment, or familiarity between sexual partners. Examples are sex in casual relationships, one-night stands, extramarital sex, prostitution, or swinging.

Attitudes to casual sex range from conservative and religious views, the extreme of which may result in imprisonment or even capital punishment for sexual relations outside heterosexual marriage, to liberal or libertarian views, the extreme of which is free love.

In the United States in the 1920s, "petting parties", where petting ("making out" or foreplay) was the main attraction, became a popular part of the flapper lifestyle, which diminished after the end of the Roaring Twenties.

During the sexual revolution in the United States and Europe in the 1960s and 1970s, social attitudes to sexual issues underwent considerable changes. The advent of the pill and other forms of birth control, the Women's Liberation movement, and the legalization of abortion in many countries is believed to have led to a wider practice of casual sex. Most religions disapprove of sex outside of marriage (see religion and sexuality).
