The 23 year-old, who plays the lesbian vampire queen Sophie-Anne
in the hit American TV series True Blood, made the comments in an
interview with Metro.
"I've always felt this way about myself since I can remember,
since I was a little girl," she says. "I grew up being
terrified of it and not understanding it. No one explains it to
you. It's something that no one ever discusses. So I remember
growing up and seeing women and actresses who had come out and were
open about it, and it made me feel so much better.
"I didn't even know bisexuality was a thing until I heard
[actress] Fairuza Balk talk about it when I was a kid. I was like:
'Oh my God, you can like both - and that's OK'. It was
revelation."
Wood, who has played several lesbian characters during her
career, lso said that telling her parents was difficult.
"It's always one thing to say that and it's another to be
presented with it. They dealt with it really well but it is always
hilarious talking about sex with your parents.
"Whatever sexuality you are, they don't really want to
acknowledge it either way. So they were fine with it but they don't
really want to talk about it."
She stars in the new George Clooney film The Ides Of March,
which opens on Friday.
