The actor can currently be seen at the centre of a love triangle in the romance Cocktail.
He told The Times of India: "A great part of my career has been based on my lover boy image. I'm glad that Cocktail allows me to be charming on-screen and my character Gautam has a lot of energy.
"People say that I've excelled in lover boy roles. I do feel I have a range. I no longer feel tied down to the genre. I enjoy doing it, but I've started liking other kind of movies. Omkara, Aarakshan, Kurban, Agent Vinod and Race 2 are movies that I like.
"An actor should never be stifled by being asked to do the same thing over and over again."
He added: "I am romancing two girls at one go. The girls are fantastic. At a basic level, they represent two kinds of women; Meera is more conventional and emotional, while Veronica is western and wild.
"The film also traces the story of Gautam and his growth as well. Initially, he would have never looked at a girl like Meera. But he soon realises where his real feelings lie.
"In real life my idea of love is different. There was an Ayn Rand character who said that she doesn't trust love unless it comes in a slightly twisted form - that's me. I see more beauty in that. I might find Meera a bit boring in real life."
Khan and co-star Deepika Padukone have denied the film is similar to their most well-known project together Love Aaj Kal.
The Agent Vinod star will be marrying long-term girlfriend Kareena Kapoor on October 16.
