The "Jennifer's Body" actress claims men are driven by sex, which their girlfriends or wives can use to their advantage.

She said: "Women hold the power because we have the vaginas. If you're in a heterosexual relationship and you're a female, you win."

The 23-year-old star also insists her sexy reputation is unfounded, and says she can count on one hand the amount of men she has undressed in front of.

She added: "I never call them guys. I always called them boys. Maybe it's a superiority complex - my needing to keep them down."

Megan – who has an on/off romance with actor Brian Austin Green - loves being in a relationship, and finds it easy to not flirt with other guys when she is committed to a man.

She explained to America's Cosmopolitan magazine: "I can flip on a switch in my brain, and even if the next Brad Pitt is standing next to me, I won't look at him. But I can also turn that switch off, and then I collect attractive boys."

"It's fun when someone intends to put you in his back pocket, but instead, he walks away wounded. I make it a mind game so they don't know if I'm hitting on them or mocking them."

Although she insists she is a one-man woman, Megan has no problem discussing which Hollywood stars she finds attractive.

She revealed: "I'd like a sexy sandwich with Andy Samberg and Jonah Hill."
