<P> The series follows a group of 7th graders, including best friends Nick Birch and Andrew Glouberman, as they navigate their way through puberty, masturbation, and sexual arousal in the suburbs of New York City . Acting as sex - based shoulder angels are the hormone monsters: Maurice, who pesters Andrew and occasionally Nick and Jay; and Connie, who pesters Jessi and occasionally Missy . Throughout the series, the kids interact with people and objects who are personified in one way or another and offer helpful, albeit confusing, advice in their puberty - filled lives including the ghost of Duke Ellington, a French accented Statue of Liberty, a pillow capable of getting pregnant, and even Jessi's own genitals . </P> <Ul> <Li> Nick Kroll as: <Ul> <Li> Nick Birch, an almost - adolescent boy living with loving and overprotective parents .
