Jean Milburn is Otis's mother and a renowned sex therapist in Sex Education — a frank, brilliant, sometimes overbearing expert on intimacy who is far more assured with her clients than with her own son. Warm, witty, and unfiltered, Jean embodies the show's open, compassionate approach to sex even as her professional candor complicates her relationship with Otis.
Her arc balances comedy and real feeling, as Jean navigates single parenthood, her own romantic life, and the irony of being a sex expert whose family communication is fraught. The series uses her to model honesty about sexuality while exploring the limits of expertise at home. She is formidable, funny, and tender.
Gillian Anderson brings impeccable comic timing and warmth to the role.
