Model Chrissy Teigen keeps it fairly modest on the cover of Cosmopolitan's June 2014 issue, and leaves the raciness for her interview inside the magazine.

Teigen, 28, married R&B singer John Legend, 35, in September 2013 and she has no problem letting everyone in on some of their intimate marital secrets. The details of the couple's entrance into the so-called Mile High Club is one experience she not only shared with Cosmo, but she joked that it should earn her and her husband a "trophy."

"We were on our way to Thailand to see my parents, flying commercial first class," the "Sports Illustrated" model said. "We were under a blanket. We weren't even in one of those pod things. I feel like we should get a trophy for that."

When the duo isn't finding ways to pass the time on planes, they still like to keep their adrenaline up with some restaurant-style public displays of affection. Teigen says that although they aren't anywhere close to being "freaky-deaky," they do keep an open mind where PDA is concerned.

"We're very OK with PDA," the model said of personal displays of affection. "When we go to a restaurant, he loves when I wear a dress, so he can do some upper-thigh rubbing."

She told the magazine that they "hooked up" on the set of Legend's single "Stereo," but she didn't try to force a relationship because she knew he was going on tour.

"I let him be himself for a while," Teigen said of when he went on the road. "The worst thing you can do is try to lock someone like that down early on, then have them think, 'There's so much more out there. '"

She continued: "I played it cool for a long time. Never once did I ask, 'What are we?' Marriage was never my goal, because I've never been very traditional. I was just happy to be with him."
