The growing acceptance of the concept of primary femininity suggests inquiry into the process through which adolescent girls integrate their rapidly developing, specifically female sexual capacities. A review of classic observations makes it apparent that, in heterosexual adolescence, the girl comes to terms with her fertility and increasing sexual excitement and with intensified wishes both to draw the opposite sex to herself and to be penetrated by the male. A discussion of these issues provides an interpretive matrix for an examination of themes of female adolescent sexual development in Anne Frank's The Diary of a Young Girl.
