Sex Education primarily follows Otis Milburn, an insecure student at Moordale Secondary School. Otis begins the series ambivalent about sex, in part because his divorced mother Jean is a sex therapist who frequently has affairs with her male suitors, but is unable to maintain romantic relationships.
