<p>Things that make you say, "Hmmmm"....</p>
<p>"As the writer of a blog called Sex and the Ivy, Harvard student Lena Chen promotes herself as something of an authority on sex. The 20-year-old sociology major is a minor celebrity around campus for her musings on hook-ups, booty calls and friends with benefits. So Chen, as self-appointed poster girl for what could be called a group of brainy girls gone wild, was an obvious choice to document a week's worth of conquests for a national magazine's online sex diary.

<p>Chen says she's since broken her dry spell, but the episode illustrates a paradox of modern college life: students are publicly documenting their sex lives more than ever, making it easy to get the impression that elite campuses are an equivalent of the sex club in "Eyes Wide Shut," with a perfect SAT score as the password.</p>

Despite this, blogs such as Chen's, student-paper sex columns, student-run sex magazines like Harvard's H Bomb, Yale's SWAY (an acronym for Sex Week at Yale) and Boston University's Boink have proliferated. </p>

One answer is that in an era of online exposure, where changing definitions of privacy have shifted sexual mores for the young, enterprising students no longer see a distinction between their bedroom behavior and their publishing activities. Rather than something to destroy upon graduation, they may even consider their magazines, blogs and columns r</p>
