text_A: The critic Edward Champion notes that Updike's prose heavily favors "external sexual imagery" rife with "explicit anatomical detail" rather than descriptions of "internal emotion" in descriptions of sex. In Champion's interview with Updike on "The Bat Segundo Show", Updike replied that he perhaps favored such imagery to concretize and make sex "real" in his prose. Another sexual theme commonly addressed in Updike is adultery, especially in a suburban, middle class setting, most famously in "Couples" (1968). The Updikean narrator, on the other hand, is a man who refrains from "infidelity and abandonment of his family".
text_B: Does the controversial sexual imagery in Updike's stories likely come from first-person accounts given by the narrator?
NO.
