How to Look Good Naked

From playing a sex addict on "Shameless" to a six-packed pirate on "Black Sails," Zach McGowan fills the bill for the latest edition of "Ali Interviews a Hot Guy." The sexy actor made waves in 2012 for his full-frontal scene on "Shameless." Zach's past time spent modeling for art classes helped him ease his anxiety about the scene. "At first I got really nervous," he says, "but then after a while it became, like, no big deal."

With notoriously cold sets, shrinkage is a definite concern. Zach was on his own to make sure his member looked its very best. "There's no fluffer, unfortunately," he says, admitting he searched online for tips to look great naked. "You kind of just have to keep yourself warm. If you drink a lot of water, that helps."

Zach's enjoying his most recent project, playing Charles Vane, a pirate captain with a vicious temper on the Starz show "Black Sails." "They've taken Treasure Island, and you're meeting many of those characters 20 years before the book," Zach explains about the show's concept. "You're meeting many of the true pirates."
