Sexual racism, resistance and empowerment against racism, and muscle dysmorphia among sexual minority Asian American men
Body image research has documented that Asian American men experience disproportionately high rates of muscularity-related concerns compared to other racial groups. This is particularly pertinent among sexual minority Asian American men who face frequent experiences of sexual racism within the sexual minority community, which can significantly shape their body image attitudes. Nevertheless, limited studies have examined the impact of sexual racis…
