Zachary Quinto says “boundaries are very important to me” as he refuses to answer questions about whether he's gay.

Quinto, best known for playing a young Spock in the 2009 J. J. Abram's directed Star Trek reboot, didn't talk about the subject in a New York Times interview.

The 33-year-old actor's portrayal of openly gay Iranian-American Sasan on the short-lived VH1 sitcom so noTORIous starring Tori Spelling got tongues wagging in 2006. And an increasingly visible profile advocating for gay rights coupled with a new Off Broadway gay role are stoking those gay rumors once again.

Quinto plays Louis Ironson in the revival of Tony Kushner's groundbreaking AIDS drama Angels in America.

He's also an enthusiastic supporter of gay marriage and repeal of “Don't Ask, Don't Tell,” the Pentagon policy that bans open gay service. And has also spoken out about the recent rash of gay teens bullied to death.

But he's not speaking about whether he's gay or straight, telling the Times: “The fact that these things are such hot-button issues right now, socially and politically, I would much rather talk about that than talk about who I sleep with,” Quinto said. “I would love to be a voice in this maelstrom of chaos and obsessive celebrity infatuation that says, 'Let's talk about something that matters.'”
