Sex Education

2019 • TMDB 8.2 • 4 seasons • 32 episodes • Comedy, Drama • Netflix

Overview

Otis Milburn is the least likely sexpert at Moordale Secondary. His mum is a sex therapist, which has given him a mountain of second-hand knowledge and a total inability to talk about his own feelings. When rebellious new girl Maeve Wiley spots an opportunity, the pair set up an underground sex therapy clinic in a disused school toilet, charging classmates for advice on everything from crushes to performance anxiety. What follows is a warm, filthy and surprisingly tender coming-of-age comedy that treats teenage sexuality with rare honesty: nobody here is a punchline, and every awkward encounter comes with real consequences. As Otis, Maeve and their best friend Eric stumble through first loves, family chaos and the minefield of school politics, the show grows from a cheeky premise into something much deeper — a story about learning to be honest with yourself, and with the people you love. Funny, frank and endlessly quotable, it is one of Netflix’s most beloved British comedies.
