Megan Fox may not mind kissing girls onscreen, but in real life, the 23-year-old "Jennifer's Body" star says she likes to dominate men in her relationships.

"Women hold the power, because we have the vaginas. If you're in a heterosexual relationship and you're a female, you win," she said in an interview for the October issue of Cosmopolitan. "I never call them guys. I always called them boys. Maybe it's a superiority complex — my needing to keep them down."

Although she's had a very on-again, off-again relationship with her beau, Brian Austin Green, she told the magazine that she has "no problem" with committing to someone. "I have no problem with commitment — you can't have a real relationship without it," she said. "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."

In addition to revealing her fear of "touching newspaper" and regret that she wasn't in "The Hannah Montana Movie," Fox also talked about the challenge of dating actors, because they always try to flash their power and money in her face. "It's fun when someone intends to put you in his back pocket, but instead, he walks away wounded," she said. "I make it a mind game, so they don't know if I'm hitting on them or mocking them. Male actors drop lines about their private jets, trying to seem powerful, but I don't give a sh--. I don't need someone else's power. I'm obtaining my own."
