William John Fielding, Sex and the Love-Life (1927)
“ Infantile sexuality is quite devoid of centralization and specific organization. It is widely diffused over all parts of the body. As the child approaches puberty, however, the erogenous zones tend to concentrate to the region of the reproductive organs. Nor are the psychic and social expressions of sexual feeling absent in the prepubescent period. Choice in the matter of affections, jealousy, a leaning toward one of the sexes, and a preference for the parent, or other near relative, of the opposite sex—as so often observed—are widely manifested by very young children. ”
