In contemporary Vietnam, young, unmarried, educated women are struggling to negotiate the contradictory expectations of femininity. Qualitative research conducted in Hanoi with 13 unmarried, educated women, aged from 25 to 34 years, explored women's sexual agency in a context of changing discourses on sexuality and gender roles. Interviews were conducted several times with each woman to enable in-depth understanding of sexual experiences and meanings. Either implicitly or explicitly, women in the research were found to resist the power of public discourses on femininity and sexuality. Notions of femininity can be interpreted as a temporary means for women to gain control over sexual relationships. It is crucial to acknowledge the sexual agency of unmarried, educated women and its diverse forms in order to understand complex sexual behaviours and to promote their sexual rights and health.
