This paper critically explores how queer youth experience sport for development programmes in Brazil. Whilst the Sport for Development and Peace (SDP) field is not void of discussions that touch upon heteronormativity and sexuality, the ‘sensitive’ stories of lesbian, gay, bisexual and transgender (LGBT) individuals within SDP initiatives remain rather unheard. Drawing on ethnographic methodology and queer theory, this paper aims to understand the impact of two different SDP programmes located in Sao Paulo, Brazil, that use sport to address sexuality and gender issues as part of their mission. The findings of this study indicate that delivery of sexuality-focused projects is a complex, problematic and contested process. Whilst the programme is conceived of as and committed to being LGBT-inclusive, the space is not completely void of heterosexism and homophobia. The queer lens here allowed for the revelation that whilst the SDP initiative provided a relatively supportive environment regarding the free expression of queer desires, it creates rather ‘safe(r)’ spaces, as the conventional norms of mainstream hetero-patriarchal society permeate these spaces. Furthermore, initiatives led to new means of exclusion and alienating experiences for its non-queer beneficiaries. Ultimately, raising the question of sexual diversity resulted in unexpected consequences outside the SDP space associated with misinterpretations, suspicions and a rejection of the initiatives. The conclusion consists of overall reflections regarding the use of the queer approach within SDP research and suggests possible directions for future studies of this topic.
