Actress Emmy Rossum insists that she's not as approachable as her character Fiona Gallagher in TV series `Shameless`.

In an interview to Cosmopolitan magazine, the actress said that although she's had sex on a first date, she doesn't consider herself to be as easy to bed as her character in the US remake of the hit series, reports contactmusic.com.

She explained: "I feel like on the first date with a guy he'll think I'm easy (like Fiona), and that's so disconcerting.`

"It's not like I haven't had sex on the first date, but usually that ended up in a two year relationship."
