Otis, a sixth form student whose mother Jean is a sex therapist, struggles with his inability to masturbate. His best friend Eric, who is openly gay, informs him that everyone in their class has had sex over the summer, except Otis. Adam, the school bully and the son of the headmaster, is unable to orgasm after sex with his girlfriend Aimee. Aimee shares her troubles with Maeve, who has a reputation for being promiscuous. Adam and Otis are assigned partners; when Adam comes over to Otis's house, he discovers all of Jean's paraphernalia despite Otis's efforts to hide it. The next day, Adam tells everyone in class, causing an embarrassed Otis to rush out, with Maeve going after him. Later, they find Adam in an abandoned building, unable to calm down after having taken three Viagra pills. Adam explains his situation, and Otis gives him advice to own his narrative. The next day, Adam exposes himself in front of the entire cafeteria as a means of "owning his narrative." He is able to achieve orgasm with Aimee, but she dumps him as he is now an embarrassment. Maeve proposes to Otis that they run a sex therapy clinic at the school – with Maeve handling the logistics and Otis providing the therapy – and split the profits.
