As Dr. Peter Newmans, a celebrated sex therapist in his early thirties, delves into the intricate world of human intimacy through his best-selling book, he finds himself in a curious contradiction: despite his mastery in the field, he is emotionally detached and physically indifferent towards the notion of romance. The ever-observant Michelle is the one to notice this paradox unfold, especially as her own life takes a turn after she ends a demanding relationship with her work-focused partner. Peter’s life takes another unexpected twist when he grapples with persistent migraines, which culminate in a serious incident—a debilitating groin injury that forces him to confront his own vulnerabilities on the court.

Upon receiving a diagnosis from hospital examinations, Peter learns that a benign brain tumor has been subtly stunting his hormonal development, leaving his reproductive system in a state of dormancy. However, with the possibility of a surgical fix comes a spark of hope—this procedure may help awaken his neglected maturity and unveil new experiences in intimacy. While he recuperates at his parents’ home post-surgery, his friends, well-meaning yet unconventional in their methods, try to reignite his sleeping sexuality, but their attempts largely fall flat.

As Peter begins to navigate the nascent stirrings of puberty, the changes in his life spark a whirlwind of emotions that are difficult to control. When Michelle heads off to a culinary retreat, Peter is left wrestling with unsettling feelings of jealousy and possessiveness during their FaceTime chats. Helpful advice from his teenage neighbor hints that casual encounters could be a solution to his new needs; thus, Peter plunges into a world of rapid Tinder escapades.

When Michelle returns, Peter’s newfound self-awareness leads to a disastrous misunderstanding, and his arrogant demeanor pushes her away. With a controversial incident threatening his professional integrity and his relationships crumbling, he stands at a crossroads in his life. A heartfelt discussion with his father becomes a pivotal moment for Peter, as he is compelled to reckon with the intricacies of love, identity, and the very essence of the human experience.

Through the process of refining his manuscript, Peter reaches a significant epiphany: the celebration of open and consensual sexual exploration represents a vital part of adulthood. He conveys sincere apologies to those he has affected, particularly to Michelle, embarking with her on a beautiful romantic journey. Their love flourishes, leading to an unexpected surprise—Michelle’s pregnancy, which deepens their connection. In time, Peter channels his transformative experiences into a new book aimed at guiding teenage boys towards emotional maturity and responsible masculinity. Years later, Peter and Michelle find themselves in a fulfilling life, overflowing with love, joy, and mutual respect.
