Fourth, we have developed an imperialistic, colonial mentality about public health in the developing world, rooted in modern Western assumptions about sex. We assume that modern, technologized cultures will have more sex as they follow the pattern of secularization that has characterized Western modernity. We do not question whether secularization is necessary or even good. Nor do we challenge the assumption that women (or men) will benefit from the de-sacralization of sex.
Fifth, we've made sexual transactions cheap precisely because they are so abundant, and the losers are women. Analysis of demographic data from 117 countries has shown that when men outnumber women, women have the upper hand: Marriage rates rise and fewer children are born outside marriage. An oversupply of women, however, tends to lead to a more sexually permissive culture.
