This paper, based on the perspectives of young men, explores the relationship between dominant constructions of masculinities and the sexual harassment of young women in Australian secondary schools, within a feminist poststructuralist theoretical framework. Of particular importance in this process are the ways in which sexual harassment is integral to the construction of hegemonic heterosexual masculine identities; the importance of popularity, acceptance and young men's fears within male peer group cultures; and the utilization of sexual harassment as a means through which to maintain and regulate hierarchical power relationships, not just in relation to gender, but how it intersects with other sites of power such as "race" and class. It is highlighted that sexual harassment is considered a legitimate and expected means through which to express and reconfirm the public and private positions of 'hegemonic masculinity' within a heterosexualized, racialized and classed gender order.
