And if you look around the world there is a fuckload of different ways people got together, some involving choice of the participants, some not. And in situations where choice is limited affairs have ALWAYS been an option and male attractiveness has always been big thing. Read ancient love poems (Song of Solomon anyone?
# A bundle of myrrh is my well-beloved unto me; he shall lie all night betwixt my breasts.
# My beloved is unto me as a cluster of camphire in the vineyards of Engedi.
# Behold, thou art fair, my love; behold, thou art fair; thou hast doves' eyes.
# Behold, thou art fair, my beloved, yea, pleasant: also our bed is green.
# The beams of our house are cedar, and our rafters of fir.
She likes his doves' eyes. Yeah, really.
