Khloe Kardashian says Kris Jenner showed her herpes photos to scare her out of having sex as a teenager

• Khloe Kardashian said her mom, Kris Jenner, used photos of herpes to scare her out of teenage sex.
• Kourtney Kardashian added that Jenner also preached no sex before marriage, though her advice didn't stick.
• Sexual health experts are divided over using fear-based tactics to prepare teens for sex.

Khloe Kardashian revealed that her mother Kris Jenner used scare tactics to teach her about sex when she was a teenager.

In a clip from The Ellen Show's "Lady Parts," a miniseries about sex hosted by actress Sarah Hyland, sisters Khloe and Kourtney Kardashian discussed family planning, how they first learned about sex, and lessons their parents taught them.

When Hyland asked what the sisters' first sex talks with their parents were like, Kourtney described an abstinence- and fear-based approach.

Kourtney said her parents preached no sex until marriage to all three Kardashian sisters when they were teenagers. That's when Khloe recalled how her mother, Kris Jenner, instilled a bit of fear in her daughters.

"I was so afraid of getting pregnant. I mean, my parents would scare the s--- out of me and would show me like, 'This is herpes,' and would show me photos," Khloe told Hyland. "I had to look at all these visuals and if I had sex, that was going to happen to me."

Experts do not advise scare-based tactics and abstinence in sex ed

Sex educators have debated the use of scare tactics. On one hand, showing imagery of the consequences of unprotected sex could make students feel more confident and equipped to take charge of their health.

At the same time, fear-based approaches can be misleading because not every person with an STI shows physical symptoms. Therefore, they could add to existing stigma and misinformation, Tulane University public and reproductive health professor Alyssa Lederer wrote.

Additionally, experts have disproven abstinence-based sex education as an effective way to prevent teen pregnancy and STIs.

According to Khloe, the imagery Kris showed pushed her to go to the gynecologist at age 14 or 15 and go on birth control. She said the decision made her feel safer because it prevented her from becoming pregnant, though no form of birth control completely protects against herpes.

Kourtney said Kris didn't employ the same approach with her when it came to the sex talk.

Khloe told Hyland she had the added benefit of learning about sex from her two older sisters, Kourtney and Kim, when she eavesdropped on their conversations.

"I think I had it easier because of Kourtney and Kim. Like when you're the third child, they've already heard it all," Khloe said of her parents. "I think the shock of their daughters having sex before marriage already went out the window."
