Thankfully this does not mean the laughs and drama are in short supply, with Otis Milburn ( Asa Butterfield ), Eric Effiong (Ncuti Gatwa), Maeve Wiley (Emma Mackey) and all of the regular characters to get into some unique and sexy situations.Sex Education season 3 release date, cast, plot and trailer for Netflix hit
