A one-night stand is a single sexual encounter between individuals, where at least one of the parties has no immediate intention or expectation of establishing a longer-term sexual or romantic relationship.
Anonymous sex is a form of one-night stand or casual sex between people who have very little or no history with each other, often engaging in sexual activity on the same day of their meeting and usually never seeing each other again afterwards.
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.
During the sexual revolution in the United States and Europe in the 1960s and 1970s, social attitudes to sexual issues underwent considerable changes.
A study of hookup culture at the University of Iowa found that waiting to have sex does not contribute to a stronger future relationship.
Data on gay and lesbian students show mixed results, as some research shows that they engage in hookups at the same rate as heterosexual students while others suggest that it occurs less due to college parties not always being gay-friendly, as most hookups occur at such gatherings.The advent of the pill and other forms of birth control, the Women's Liberation movement, and the legalization of abortion in many countries are believed to have led to a wider practice of casual sex.Most religions disapprove of sex outside marriage (see religion and sexuality), although the consequences may be very serious, or none.More and more people are turning to the internet and using dating websites to help them find a partner.There are hundreds of thousands of success stories, and the stigma once attached to the use of online dating websites, that it’s the last resort of desperate people, is long gone.Many specialist online dating services or other Internet websites, known as "adult personals" or "adult matching" sites, cater to people looking for a purely sexual relationship, without emotional attachments.
