Sure, she juggles a career and two daughters (Violet, 4, and Seraphina, 1), but Jen Garner says she still manages to keep the sparks alive with husband of four years, Ben Affleck.

"You steal the time. You steal a date, you steal a kiss, you steal a whisper. You sit next to each other on the couch with computers on your laps. After the kids are asleep you...well, you know," the Valentine's Day star, 37, tells Parade. "Whatever it is. You slip away for a night, which we've only just now done for the first time. Of course, I call home while we're away. Ben would be surprised if I didn't."

She began dating Affleck, 37, after her 2003 split from actor Scott Foley.

"Well, it helped that we were both single at the time," she says of falling for Affleck, her costar in the 2003 comic-book movie Daredevil. "He's a very good writer."

Asked if he wooed her with letters, she says, "Don't make assumptions. I didn't say that! Okay...e-mail. He's a very persuasive writer."

She describes her husband as "sexy and kind, but he's also a riot. We can be very goofy together."

He's also a family man: She says he didn't have to work hard to win over Garner's mom and sisters.

"He doesn't have trouble wiggling his way in anywhere," she says. "Ben is charm personified when he wants to be. He's not easily threatened or made uncomfortable--he's very secure in that way. Maybe he just knows I'm nuts about him, and he doesn't have anything to worry about."
