Hours after Kim Kardashian's sister Khloé Kardashian got candid about having sex for the first time, the 35-year-old mother of two opened up about sex and love during a live Q-and-A on her website.

During the livestream, one of Kim's fans asked the "Keeping Up with the Kardashians" star if she was a member of the mile-high club.

"Am I? Yeah," Kim told her assistant Steph, who was asking her all the questions. "But, like, the private. I don't think, like, a public plane... It would have to be an international flight. It was an international, night flight when no one's, like, around."

While an airplane bathroom is certainly not the bedroom, Kim went on to reveal that a plane was nowhere near the craziest place she has ever had sex. So what was?

"Like, a public movie theater, yeah," she said.

The reality star did not reveal who the lucky men were, but her husband Kanye West did rent out a movie theater in Prague during their honeymoon where they watched "X-Men: Days of Future Past," and also rented out a theater in Los Angeles for her 35th birthday where they watched "Steve Jobs."

Earlier in the day, Kim's younger sister Khloé opened up about a bunch of firsts in her life, including her first kiss, the first time she said "I love you" and when she lost her virginity. The 31-year-old said she had her first kiss when she was 12 or 13 years old when she was on a family vacation to Hawaii, and then revealed she told her boyfriend when she was 16 that she loved him and had her heart broken for the first time when she was 17.

Khloé then got very candid with her fans and shared the story of how she had sex for the first time when she was 15 years old.

"It's not funny to lose your virginity! It's weird and you're scared and it hurts and you don't know what will happen," Khloé wrote. "I was 15 and he was an older guy who wasn't a virgin. I don't really remember it hurting but I do remember that I just wanted to get it over with. You definitely don't have an orgasm your first time. I didn't for the first few years! I didn't even know what the feeling was until I had one; I just liked the intimacy part. When it happened, I was like, "Ohhhhh, that's what that is!!!"
