The Japan Times reports that nearly half of unmarried adult Japanese men and women are virgins. Decades of social "reforms" have left the Japanese population docile to the point sex outside a marital contract rarely happens, and Japan's low birthrate suggests that even marital contracts to little to promote sex among those residents of Japan who managed to lose their virginity.
A similar though less developed trend of sexlessness is beginning to emerge in the young adult population in the United States, though rampant transmayogenderism complicates comparisons by as many young Americans can be visually identified as sexually defective from a distance. Japan's increase in obesity lags their growing sexlessness while American sexlessness lags their increasing obesity. The failure of the fundamental biological drive to "make baby" suggest deep defects at the societal and personal level in both cases.
Peace (by attrition) in our time.
