Khloé Kardashian has made a sex tape and stripped down in a candy-filled bathtub — so, well, this is nothing. The Keeping Up With the Kardashians star revealed on Monday, January 25, the three wildest places she's ever had sex.

Kardashian, 31, posted the juicy tidbits on her website khloewithak.com. Even more, she ranked each spot.

"I'm not out there getting freaky in the craziest places, but I've had my fair share of chasing a thrill," Kardashian prefaced before noting that she's a member of the mile-high club.

"Doing it on a private plane is great, especially when there are other passengers on board. It's part of the thrill!" the Strong Looks Better Naked author wrote, giving the experience a 5 out of 5 rating. "I walked into the bathroom first and then he followed so it wasn't exactly stealth, haha!!! Everyone obviously knew what was going on in and when I walked out, they asked if we had fun, LOL!!!"

Kardashian also gave the same score to a room in her estate. "You're at home, so it's comfortable, but it's still a little different than the norm," she explained. "A marble kitchen counter is sexy, thrilling...and cold, LOL!"

The reality personality warned that other places just aren't as fun, though. Case in point: that time she tried to have sex in a car.

"Someone else was driving and I was in the backseat, but I'm a tall girl so it feels cramped and it hurts my f--king knees. Getting down in a moving car is a waste of time, because nothing happens for me. I just don't get to the finish line!" she wrote. "If you're down for a thrill, then by all means, but this one gets a low rating from me!"

The score she gave? A measly 2 out of 5.
