Kourtney Kardashian is focusing on all the small things in life.

That's why she and her husband Travis Barker will take time to mark every relationship milestone, including the first time they ever had sex. As the reality star noted, "You have one life on this planet and we like to have an extra reason" to celebrate.

"Today is the three-year anniversary of the first time we were ever together," Kourtney revealed during the June 13 episode of The Kardashians, which was filmed in October before the couple welcomed their son Rocky. "We got engaged one year later on the same date."

To mark the occasion, the Poosh founder got Travis a special prop from True Romance, the movie they watched together on the night of their first hookup.

"It's his favorite movie," Kourtney explained. "So, I found the actual wedding rings from the movie." (To keep up with the Kardashian family, tune into Kards Katch Up every Thursday.)

During a conversation with her mom Kris Jenner, the 45-year-old also voiced concerns that her water would break before Travis arrived home to celebrate their special anniversary.

"I need to have sex," she quipped, prompting the momager to question why "sex is taking a priority over birth." 

Kourtney's response? "Because you can't have sex for six weeks after."

But prop wedding rings weren't the only present Kourtney gifted Travis ahead of their baby boy's birth. As she revealed on the Hulu series' May 30 episode, the Lemme creator also gave the Blink-182 drummer a vial of her blood so they could "just to have each other's" around the house.

New episodes of The Kardashians air Thursday on Hulu.
