Khloe Kardashian, 14
Like her sister Kim, Khloe Kardashian also lost her virginity at 14. The reality star has been open about her first time and revealed in her book that she did it to impress her much older boyfriend.
“I was only 14, but I thought I was so mature, and I look back and see how wrong I was,” said Khloe. “Having sex for the first time is an extremely important decision that affects your whole life. You should never, EVER have sex when you’re that young. Feeling rushed and pressured and unsure should have been my clue that I wasn’t ready to take that step.”
