Michael Fassbender is worried that being an actor will only attract women who are interested in him because he's famous.

The British star discusses his fear in the November issue of GQ magazine, saying, "You become a lot more successful in terms of, like, talking to a girl. She's all of a sudden more interested in me. I know that, like, three years ago, she would've walked away after two sentences left my mouth."

The "Prometheus" star says his longest relationship lasted only two years, and perhaps that has something to do with his fear.

"I was talking to this girl, I was like, 'God, I am so boring right now,'" he adds. "But she was like, 'That's so interesting!' I was like, 'You know what? Five years ago, this would not have been interesting.'"
