Ryan Reynolds has spoken about his reluctance to speak about his marriage to Blake Lively, and opened up about his desire to have a "big family".

The Green Lantern star said that he cannot put into words his feelings for Lively, who he married in a secret ceremony in September 2012.

Reynolds said in an interview with Details magazine: "I don't intentionally try to be evasive about that stuff. If you ask me to describe my relationship, I mean - words are too clumsy to accurately describe how I feel in that regard, particularly in an interview.

"It's a strange thing. I understand the climate we live in and why people are curious. But it's just tough and almost emotionally violent - for anyone, I think - to see your personal life summarized in a sentence."

The 36-year-old star added that he and former Gossip Girl actress Lively would like to have a big family together.

He said: "We'd love to have a big family. We both come from big families - my parents did four [children], Blake's did five.

"A lot of people say it's crazy, but we'll only know when we're there, you know? We'll walk through that fire pretty happily, I think."
