Exercise unleashes dopamine, the feel-good chemical, but did you know that it can also trigger testosterone production?

Hit the Books
That California sextress on the beach with a book in her hand isn’t just sweating it out in the sun—she’s putting her brain to work. “Explorers could be reading everything that Shakespeare wrote, and then watching all of his plays,” Fisher says. Remember how you secretly enjoyed reading Faulkner in college? Pick up a few of his books. A University of California-Davis study found that women prefer smart men when it comes to one-night stands.

Be Spontaneous

While you don’t have to go jump off the nearest cliff, seeking adventure certainly isn’t going tohurt your libido.
