Sex-positivity is a political position that embraces sexuality and sexual expression, with an emphasis upon safe and consensual sex.
It also advocates for comprehensive sex education and safe sex. Many asexual spectrum people are sex-positive in this sense, and it is possible for an asexual to be repulsed by sex on a personal level while being sex-positive in regard to other people.
The term "sex-positive" is sometimes confused with the term "sex-favorable", which refers to asexual people who enjoy sex under the right circumstances.
History
In general use, the term "sexual liberation" is used to describe a socio-political movement, witnessed from the 1960s - 1970s. However, the term has been used since the late 1920s and is commonly attributed as being influenced by Freud's writing on sexual liberation and psychosexual issues, as well as Wilhelm Reich, who originally coined the term.
In the 1960s, a shift in the ways people thought about sexuality began to take place, which began a period of de-conditioning in some circles away from old world antecedents, and developing new codes of sexual behavior. The 1960s also heralded a new culture of "free love" with millions of young people embracing the hippie ethos and preaching the power of love and the beauty of sex as a natural part of ordinary life. Hippies commonly believed that sex and sexuality were natural biological phenomena which should be neither denied nor repressed. These changes in attitudes reflected a perception that traditional views on sexuality were both hypocritical and chauvinistic.
The term sex-positive first came in into use in the United States in the late 1990s with the founding of the Center for Sex and Culture in San Francisco, California and The Center for Sex Positive Culture in Seattle, Washington. In 2009 Sex Positive World began in Portland, Oregon. As of 2019 there are more than sixteen chapters of the nonprofit, in five countries.
Sexual liberalization heralded a new ethos in experimenting with open sex in and outside of marriage, contraception and the pill, public nudity, gay liberation, legalized abortion, interracial marriage, a return to natural childbirth, women's rights, and feminism. Because of this, the polyamorous and WLW/MLM groups were positively effected by this movement, making it an important piece to the LGBT+ movement.
