At least Bi. Ezra already played two gay caracters: "Every Day" (2010) and will play gay again in the upcoming "The Perks of Being a Wallflower" (2012). On being questioned about what he thinks about Tom Hardy's famous declaration that he had gay sexual experiences, he said:
"Of course! Many! I've had many, you know, "happy ending sleepovers" in my early youth - my period of exploration. I think that's essential. Anyone who hasn't had a gay moment is probably trying to avoid some confrontation with a reality in their life."
After being questioned if he's planning to have another gay moment in the future and if guys can have any hope for crushing on him, he said:
"I'm not sure. Perhaps. I keep my options open. My spectrum remains broad. I've been in love with a lot of girls lately but that doesn't necessarily suggest anything definite about the future."

I think you mistake "sexual orientation" with specific types of orientation. Sexual orientation is a part of every humans make up. A person can not have a sexual orientation. Your sexual orientation is what makes you gay, straight or bisexual. Homosexuality IS illegal in some countries. You can outlaw a behavior but you can't outlaw an urge or feeling.
