SEXY SCIENCE!—Sex sure seems like something louts do, with all that sweating and grunting and moaning. But even nerds do it. Because it's actually quite scientific. OMSI: After Dark has a whole buffet of sexy learning on tap tonight—digging into the relative alchemy of lube, pheromones, and vibrators. And that's not counting trivia, storytelling, and dancing. Learn something, and then try it out! DCT

READING—As an odd youth growing up in a suburb, reading Armistead Maupin's wildly entertaining Tales of the City series introduced me to a vibrant reality that existed outside of my homogenized world. So it was with heavy heart when I learned Maupin is hanging up this heartfelt, hilarious saga with his newest (and last) installation, The Days of Anna Madrigal, documenting the perhaps final road trip for 28 Barbary Lane's beloved transgender landlady.
