Legal and social norms regarding gender relations have undergone dramatic changes in the past 25 years. The changes have come about largely because of the confluence of changing economic and technological realities, the unfolding of the norm dictating equal treatment of individuals, the sexual revolution and its corollaries of improved contraception and legal abortion, the rise of women as a self-conscious group and a presence in the academy, and the interrelations of all of these factors. As men and women have come to share dormitories and workplaces, and as the old mores governing sex—and male-female relations in general—have broken down, there has been struggle and uncertainty over what norms should apply to sexual relations.
