Episode 1
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 else in their class had sex over the summer. Adam, the school bully and son of the headmaster, is unable to have an orgasm with his girlfriend Aimee, who shares her troubles with Maeve. When Adam comes over to Otis’s house to work on a school project, he discovers Jean’s sexual paraphernalia, and exposes Otis as a supposed “sex freak” to the whole school. Otis flees the classroom in embarrassment, and Maeve is sent after him. They find Adam in the abandoned gym lavatory, alarmed at his priapism after taking three Viagra pills. Adam explains the stresses that led him to take it – being son of the headmaster and the reputation of his large penis – and Otis advises him to “own his narrative”. The next day, Adam exposes his penis in the school cafeteria as a means of doing so. He is then able to achieve orgasm with Aimee, but she dumps him, as she is now embarrassed by him.
