"Grey's Anatomy" star T.R. Knight says the 16-year age difference between him and his 19-year-old boyfriend is "bound to raise some eyebrows."

"But we love each other," Knight, 35, told "Extra" on Wednesday. "He's an amazing guy."

The actor said he and Mark Cornelson have no plans to wed, adding, "We've only been together for six months, so I think it's a little soon to consider marriage."

But he does want to marry eventually.

"I think it's very important to honor marriage. I take it very seriously. And I'm glad I can finally take it seriously."

Gender-neutral marriage licenses will be issued in California beginning June 17.
