The film "Don't Tell My Partner" offers an empathetic and complex portrayal of a bisexual man navigating a secret gay relationship. It explores the internal and external pressures he faces, highlighting the challenges of authenticity and the desire for an openly affirmed queer identity. The narrative treats the LGBTQ+ characters and their relationships with dignity and depth.

The film features a character, Mandy, whose gender presentation as a woman, despite being biologically male, is central to the plot. The narrative primarily uses this aspect for comedic effect, focusing on the protagonist's shock and discomfort upon discovery. This portrayal leans negative, as it frames gender non-conformity as a source of misunderstanding and ridicule rather than affirming identity.
