大众媒体对性取向的影响。（注：原文中“sexuality”更常见的释义为“性取向”，但从字面看“对性行为的影响”也说得通，这里根据常见语境翻译为“性取向”，你可根据实际情况调整。）严格来说，按照你要求的准确翻译，“sexuality”翻译为“性行为”更合适，即：大众媒体对性行为的影响。但考虑到实际情况，“性取向”在相关语境中也较为常见，所以给出上述两种翻译供你参考。以下为最终符合你要求的翻译：大众媒体对性行为的影响。

Abstract

The mainstream mass media (television, magazines, movies, music, and the Internet) provide increasingly frequent portrayals of sexuality. We still know relatively little about how this content is used and how it affects sexual beliefs and behaviors. The few available studies suggest that the media do have an impact because the media keep sexual behavior on public and personal agendas, media portrayals reinforce a relatively consistent set of sexual and relationship norms, and the media rarely depict sexually responsible models. More longitudinal research, especially with early adolescents is needed to learn more about how media content is attended to, interpreted, and incorporated into developing sexual lives.

摘要

主流大众媒体（电视、杂志、电影、音乐和互联网）对性的描绘越来越频繁。我们对这些内容的使用方式以及它如何影响性观念和性行为仍然知之甚少。现有的少数研究表明，媒体确实有影响，因为媒体将性行为置于公共和个人议程之上，媒体描绘强化了一套相对一致的性和关系规范，而且媒体很少描绘对性负责的榜样。需要更多的纵向研究，尤其是对青少年早期的研究，以更多地了解媒体内容是如何被关注、解读并融入到正在形成的性生活中的。
