In Brazil, Carnival is not only a time for vibrant celebrations but also a space where social norms around relationships are revisited. Amidst the festive atmosphere, some couples choose to explore non-monogamy, testing the waters of open relationships temporarily during this period of revelry. This phenomenon reflects broader trends within relationships, where individuals seek to embrace their desires while maintaining ethical and consensual arrangements.

One couple, Fernando and Vitória, exemplifies this trend as they decided to experiment with their relationship at the Carnival of 2025. After six years together, they felt the urge to flirt and engage with others. They set agreed-upon rules for their four days of celebration in São Paulo, indicating a shift from conventional monogamous frames toward more flexible, modern relationship styles. Their experience is emblematic of how Carnival serves as an experimental ground for such relationship dynamics.

The rise of non-monogamous arrangements highlights changing perspectives on love and fidelity, especially among younger generations. By approaching their relationship with openness, couples like Fernando and Vitória challenge stigmas associated with infidelity and rejection of monogamy. This cultural shift suggests not only a transformation in how romantic relationships are perceived but also raises questions about emotional honesty, jealousy, and the societal expectations surrounding commitment.
