Despite concerted efforts, LGBTQ + inclusivity is not fostered across all sporting contexts. Interpersonal relationships with teammates and coaches are particularly significant when it comes to cultivating positive and inclusive LGBTQ + experiences within sport. Using online qualitative data collected from 741 LGBTQ + adults, this study examined how relationships with coaches, teammates and sport-related staff impacted sport experiences and participation. Participant responses were independently coded using reflexive thematic analysis. Data were used to develop a new visual model to understand different types of relationships LGBTQ + individuals experience in sport and how this impacted their sport experiences. Exclusive sport relationships were characterised by experiences of discrimination and were found to greatly influence how participants viewed sport and physical activity contexts as adults. Inert or neutral sport relationships were maintained through protective self-distancing techniques. Inclusive relationships with coaches and teammates were primarily based on acceptance and associated with viewing physical activity positively. Identity-concealment strategies and athletic ability were identified as factors that impacted LGBTQ + adults' relationships within sport. Our overall findings demonstrate how discrimination in the form of overt or subtle sexual and gender prejudice can thwart feelings of relatedness among LGBTQ + athletes.
