Though pretty much every issue of Zoo seems like a sex issue (or at least a sexy issue), they do, in fact, have one specific issue that is explicitly devoted to naughty business.

And to make their latest sex issue extra special—or at least extra sexy—they've recruited Madison Welch to don a mortarboard, doff her top, and spill all her best sex secrets. Hey, if this stuff works on Madison Welch, it's gotta work on women across the world, right?
