Three Contributions to the Theory of Sex - Sigmund Freud

If the transference of the erogenous excitability from the clitoris to the vagina has succeeded, the woman has thus changed her leading zone for the future sexual activity; the man on the other hand retains his from childhood. The main determinants for the woman's preference for the neuroses, especially for hysteria, lie in this change of the leading zone as well as in the repression of puberty. These determinants are therefore most intimately connected with the nature of femininity.-from \The Transformations..
