Her husband of 24 years, Kevin Bacon, has it all figured out.
"He is so honorable. He is so ethically true. He has high moral standards, and he doesn't lie and he doesn't cheat – and I find that sexy!" the actress, 47, says in the January issue of a newly redesigned Good Housekeeping.
"I don't know how he does it, but he always makes me feel like I'm the most beautiful woman in the room – the only girl in the room," she says of her relationship with Bacon, 54, whom she married in 1988.
"He says 'Honey, you look beautiful. You are sexy!' Always, always, always!"
While their love has lasted over decades – an eternity in Hollywood – the couple is experiencing a kind of "second-honeymoon" now that their children Travis, 23, and Sosie, 20, have left the nest.

"There's a lot more walking around the house naked," Sedgwick says.
But it's clearly more than occasional nudity that keeps their love alive.
"I am constantly in awe of Kevin's levelheadedness and his lack of 'crazy,' " she says.
