Having been dating Mark Cornelsen since February, Grey's Anatomy star T.R. Knight has formed some perspective on their relationship.

Specifically, in regard to their age difference.

"It's bound to raise some eyebrows," the 35-year-old, who plays Dr. George O'Malley, said in an interview with Extra. "But we love each other."

Mark Cornelsen, 19, is a student and "an amazing guy. I love being around him," says Knight. "I love what we have."

With a laugh, the actor says, "I was surprised he was interested!"

Despite the legalization of gay marriage in California - which prompted talk show host Ellen DeGeneres and others to announce that they intend to wed their partners - T.R. Knight has no similar plan for the immediate future.

"We've only known each other for six months, so I think it's a little soon to consider marriage." Still, the Grey's Anatomy star says, "I don't think you date anyone that you don't see a future with."

Asked if he's interested in having children: "The idea of it, yes," he responds. "Adopting."
