The teen-targeted website gURL. com is committed to providing educational information about sexuality and sexual health to young girls. In this article, I analyze girls' conversations posted on the site to explore how girls mediate the factual information presented, and how they challenge the borders of the scientific discourse on adolescent sexuality. Without overvaluing the freedom of online environments, I assume that the relatively unregulated space of the Internet encourages young women to create their narratives about sexuality and to imagine themselves as sexual beings. My assumptions are informed by the analyses of Susan Driver (2005), Barclay Barrios (2004) and Susannah Stern (2002): in contrast to the disempowering and alienating effects of institutional policies, I call for the recognition of less regulated sites, which imagine youth not as passive recipients but as active agents who strategically work on developing their understanding of sexuality, and on exploring their sexual selves.
