Pressured by the feeling that everyone is having sex except him, Otis (Asa Butterfield), like most teenagers, is very uncomfortable with sex, masturbation, and intimacy in general. In addition to the standard-issue teenage awkwardness, to make things worse, he grows up in a sex-positive household under the watchful eyes of his mother Jean, played by Gillian Anderson, who is a sex therapist. Obviously, the subject is omnipresent as are erotic art, oversized dildos, and coitus-craving couples all over the house.

The twist comes when he transforms his tribulations into a business model by teaming up with bad girl Maeve Wiley (Emma Mackey) to counsel his teenage peers on sexual issues of all kinds. As you can imagine, uninitiated teenagers have a lot to offer in that department. Apart from its raunchy premise and explicit images, this is a hilarious, diverse, and warm teen comedy thanks, in particular, to the writing of playwright Laurie Nunn. Lauded by critics for its honesty, this future comedy classic will surely teach you a thing or two about sexuality yourself.
