Albert Moll, The Sexual Life of the Child — The Sexual Organs… (1913)
“ Let us now pass to the consideration of the sexual impulse. We learn from personal observation that two entirely distinct processes participate in this impulse. In the first place, we have the physical processes that take place in the genital organs; these are in part unperceived, but in part they affect consciousness in the form of common sensations, or as ordinary tactile and other similar sensations. In the second place, we have those higher psychical processes by means of which man is attracted to woman, and woman to man. ”
