Let's talk about sex. For Khloe Kardashian, she was 15 years old when she lost her virginity, but the experience wasn't something she was savoring.

"He was an older guy who wasn't a virgin," she wrote on her subscription-based website and app on Monday. "I don't really remember it hurting but I do remember that I just wanted to get it over with."

Ouch!

The former "Kocktails with Khloe" host said she didn't know what would happen when she had sex for the first time.

"You definitely don't have an orgasm your first time," she said. "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!!!'"

This was all long before she needed that "sex calculator" next to her bed!

Khloe was obviously sentimental about her love life on the app. She also spoke about her first kiss, which happened during a family vacation when she was 12 or 13.

"We were in an arcade where the hotel kids hung out," she recalled. "I remember I kissed some guy there and I thought I was so cool and so grown. I don't remember the boy and I can't tell you anything else about the experience."

She said that wasn't with her famous family, but rather a friend's family on vacation. She only kissed the mystery boy because her friend kissed a boy, too.

"I lied and was like, 'I've totally done that before!', Lamar Odom's estranged wife said, adding, "but I hadn't, LOL."

Really, all those experiences left her with some sort of fondness. Her first breakup, though, wasn't the same.

"He was so mean," she said of the man without naming him. "He lived in L.A. but his mom lived in Atlanta, so on Valentine's Day, he told me he was going back home to Atlanta and just left and never came back."

"Later on, he called me and asked me to fly out there to meet him. My dad warned me not to go, but I did," she said. "The guy NEVER picked me up from the airport!!! He never showed! I got a voicemail from him and he said, 'I'm sorry. I can't do this.'"

So, here she was, a 17-year-old in Atlanta with no money or credit cards.

"My sisters told my dad and he got me a little hotel room and I took a flight back the next morning," she said. "My dad and I never, ever talked about it again. He knew how heartbroken and embarrassed I was, and I'm so thankful that he never said, 'I told you so.'"
