Meaning "quality of having a moderate opinion of oneself" is from 1550s; that of "womanly propriety" is from 1560s.
La pudeur donne des plaisirs bien flatteurs à l'amant: elle lui fait sentir quelles lois l'on transgresse pour lui; (Modesty both pleases and flatters a lover, for it lays stress on the laws which are being transgressed for his sake.) [Stendhal "de l'Amour," 1822]
