"It's good to make an effort to dress up sometimes – to do things outside of the norm," the fashion mogul, who is currently courting bodyguard Martin Kirsten, tells Marie Claire in its February issue.
"Some people are more experimental in bed and others are more boring. If you are wild and crazy, bring it on so the other person is well aware that you have little devil horns that come out every once in a while."
Klum, 39, who filed for divorce from Seal last April, doesn't understand why people call her split "devastating."
"Did I wish for this to happen to my family? No," she says. "But everyone is healthy. We're moving on with our lives. If someone got [very sick] – god forbid – that would be a real problem. It's not what I wanted. It's not what anyone wanted. But it's not a real problem."
Although Klum does not seem scarred by her split, she doesn't intend to say, "I do" again.
“I don't think [I'll get married again], no, no," she says. "I wanted to keep the memory of [mine and Seal's] wedding alive every year. That's why I thought it would be fun to get married over and over. But now I don't think it's that important. I'm not angry about anything, but I don't think I will. Maybe if I'm with someone for 15 or 20 years, and we do it in our old age as a fun thing to do. … But I don't have the urgency anymore."

"I can understand why a woman finds a young man attractive, because the truth is that when men get older, their shape changes," Klum says.
"Younger men train more, and when the clothes come off, it is nice to look at a sexy, ripped body. But I am realistic. I'm turning 40 next year. I don't think I could deal with waking up next to a 25-year-old."
