It has been almost a year since Ryan Reynolds and Blake Lively secretly tied the knot in South Carolina, and now Reynolds is finally opening up about their relationship.

Reynolds, who stars in the new film R.I.P.D., revealed in the August issue of Details his plans to start a family. 

"We'd love to have a big family," he said. "We both come from big families - my parents did four, 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." 

"I'm terrified that I'm genetically predisposed to only having boys. That's frightening. By the time I was 10 years old, and I'm not exaggerating, I knew how to patch drywall. There's nothing my brothers and I didn't put a hole in. We turned our home into a Wiffle house. That's something I'm not looking forward to," Reynolds added. 

He married Lively in a surprise South Carolina wedding last September, just one year after they began dating. Aside from a handful of photos published in Martha Stewart Weddings, the couple has kept their relationship under wraps 

"I don't intentionally try to be evasive about that stuff," Reynolds explained. "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."
