There exists two hypothetical sex organs as opposite-sex
biological mechanisms: the female organ is self-activating and internally
self-sustaining, whereas the male organ is not.
Recognition in physiological endowment that men are inferior to women: A girl is born with all the vital organs and fluids necessary for her to attain adult reproductive competence naturally. Women's own bodies internally produce the menarche, the hallmark of reproductive maturity. Girls grow easily and quickly outpacing men.There is no comparable mechanism in a boy, nothing that can stimulate his secondary traits; only semen can do that; only men have semen. Oral ingestion of semen is essential to the growth of manhood. The ritualized simulation of manhood is collective initiation rigidly structured from seven to fifteen years of age. Loss of semen is a contant worry of manhood. - Gilbert Herdt 1982 Rituals of Manhood
