With apologies for the obvious

"With apologies for the obvious, I must say that it is the primary purpose of all animals to perpetuate themselves and that furthermore it is the responsibility of the female to see to it that the job gets done. It conveniently happens that every little cell in her body is attuned to this charge, and, as with all the really big things in life – God, growing up, death, etc. – intelligent beings have a tendency to ritualize things their cells, nerve endings, and hormones so disturbingly tell them to do. The programming is there, nagging and insistent, and I wouldn't dare, for the sake of my sanity, attempt to defy all my little cells when they tell me to cast a commensurate sidelong glance. The ritual merely lends grace to the task and disguises the enormity of its truth." — Helen S. Clark, "In Defense of Rape"
