The `Black Swan` actress - who this week announced her split from actor Macaulay Culkin after eight years together - said she was brought up in a very liberal household and has always gravitated toward the gay community.
She told The Advocate magazine: "I grew up in West Hollywood, in the heart of the gay community, so I`ve always been attuned with the gays. I`ve often been told I`m a gay man in a woman`s body. I`m a massive "fairy princess," as I like to call it."
While she grew up liberal, the 27-year-old said she was always sure of her own sexuality and never had the urge to experiment.
She said: "There was no need to experiment because I knew what I wanted. I was a very late bloomer, so it took me a long time to become comfortable with who I was, physically and sexually, but once I did, I knew what I liked. All my friends were experimenting around me, though.
"I actually live vicariously through the characters I play. I love that I get to live all these different little lives."
`Black Swan`, which features Mila and Natalie Portman is released from January 20 in Europe.
