How young women negotiate sexual agency in first sex is contingent upon the specific social construction of female and male sexuality and the sexual double standards in a particular local context. Within Philippine Roman Catholicism, a strong religious moral discourse equates virginity with a woman’s honor, making first sex or virginity loss a source of shame. This has implications for women’s experiences of sexual agency. We report on research in which a group of eight young Filipina women wrote their memories of first sex and collectively analyzed these memories. Using thematic analysis, we derived five themes about why they engaged in first sex: (1) "giving in," (2) "nadala" or "carried away," (3) love, (4) self-expression, and (5) coercion. Avoiding sexual agency in giving in and nadala is linked to the experience of pain, loss, and shame. Recognizing sexual agency by articulating first sex as a need for sexual self-expression is tied to the experience of pleasure. The absence of sexual agency is seen in the experience of coercion and subsequent trauma. Despite variations in these women’s constructions of first sex, each can be seen as ways of preserving a woman’s social status and maintaining a "good girl" position.
