When does Sex Education return?

Sex Education is a British teen sex comedy drama streaming television series. It follows the lives of the students, staff and parents of the fictional Moordale Secondary School. The first series was released on 11 January 2019, the second on 17 January 2020, and the third on 17 September 2021. The series stars an ensemble cast that includes Asa Butterfield, Gillian Anderson, Ncuti Gatwa, Emma Mackey, Connor Swindells, Kedar Williams-Stirling, Alistair Petrie, Mimi Keene, and Aimee Lou Wood.
Sex Education primarily follows Otis Milburn, a student at Moordale Secondary School. Otis begins the series ambivalent about sex, in part because his single mother, Jean, is a sex therapist who frequently has affairs with male suitors but does not maintain romantic relationships. Other students include Eric Effiong, Otis's best friend and the gay son of Ghanaian-Nigerian immigrants; Maeve Wiley, a highly intelligent, rebellious teen whose independence is overshadowed by her family's troubled past.
