When does Sex Education return?

Sex Education is a British comedy-drama streaming television series created by Laurie Nunn for Netflix. It follows the lives of the students, staff and parents of the fictional Moordale Secondary School as they contend with various personal dilemmas, often related to sexual intimacy. The series stars Asa Butterfield, Gillian Anderson, Ncuti Gatwa, Emma Mackey, Connor Swindells, Kedar Williams-Stirling, Alistair Petrie, Mimi Keene, and Aimee Lou Wood. The programme has been a viewership success, with over 40 million viewers streaming the first series after its debut.
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.
