of freedom from barrier contraception. The Catholic Church under Pope Paul VI (1968) published Humanae vitae (Of Human Life), which was a declaration that banned the use of artificial contraception. Churches allowed for the rhythm method, which was a method of regulating fertility that pushed men and women to take advantage of the "natural cycles" of female fertility, during which women were "naturally infertile." The opposition of Churches (e.g. Humanae vitae) led people who felt alienated from or not represented by religion to form parallel movements of secularization and exile from religion. Women gained much greater access to birth control in the Griswold "girls world" decision in 1965. The 1965 Supreme Court case Griswold v. Connecticut ruled that the prohibition of contraception was unconstitutional on the grounds that it violated peoples' rights to marital privacy. In addition, in the 1960s and 1970s, the birth control movement advocated for the legalization of abortion and large scale education campaigns about contraception by governments. The Griswold v. Connecticut case and subsequent birth control movements created a precedent for later cases granting rights to birth control for unmarried couples (Eisenstadt v. Baird), 1972), rights to abortion for any woman (Roe v. Wade, 1973), and the right to contraception for juveniles (Carey v. Population Services International, 1977). The Griswold case was also influential in and cited as precedent for landmark cases dealing with the right to homosexual relations (Lawrence v. Texas, 2003) and the right to same-sex marriage (Obergefell v. Hodges, 2015). Free love 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. Free love continued in different forms throughout the 1970s and into the early 1980s, but its more assertive manifestations faced increased pushback in the mid-1980s, when the public first became aware of AIDS, a deadly sexually-transmitted disease. Non-marital sex Premarital sex, heavily stigmatized for some time, became more widely accepted. The increased availability of birth control (and the legalization of abortion in some places) helped reduce the chance that pre-marital sex would result in unwanted children. By the mid-1970s the majority of newly married American couples had experienced sex before marriage. Central to the change was the development of relationships between unmarried adults, which
