With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
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 narrator in an Updike story tend to be more of a role model for the reader, even among lascivious circumstances, because he stays with his family?
YES.
