Khloe Kardashian is really into documenting her sex life in many forms.

Just days after it was revealed the reality star made a sex tape with husband Lamar Odom, a source close to her spilled the beans about a sex diary she maintains. Kardashian keeps a highly-explicit sex journal where she details her encounters and grades her lovers, according to RadarOnline.com.

Khloe Kardashian Reveals Truth Behind Her Sex Tape With Lamar Odom

"Khloe was doing this before she married Lamar and started again right when they split," a family insider told the website. "He's in there, of course."

Odom and Kardashian have a tumultuous history, and they'd likely be divorced by now if the ex-NBA star didn't sustain a near-fatal overdose at a Nevada brothel back in October. Due to Odom nearly losing his life and having a long path to recovery, Kardashian put the split on hold in order to support him financially and emotionally.

James Harden Spends Night In L.A. With Strippers, Not Khloe Kardashian

That hasn't stopped her from moving on with her love life, however, as she is currently dating Rockets star James Harden. While Kardashian's raunchy side has definitely been exposed, the diary isn't just for the times she goes all the way, though there is some bizarre stuff in there.

"She has a special section for the guys she's just kissed as well as the ones she's slept with," the source said. "She's kept hold of other stuff too, like her exes' boxer shorts and even their socks. She has a special drawer at her home which is full of stuff from her past."

The "Keeping Up with the Kardashians" star has also dated rapper French Montana, and he probably surfaces in the journal as well. Kardashian has been on a media tour to promote her new talk show, "Kocktails with Khloe," and it was during this tour that she revealed her existing sex tape with Odom.

The only question now is who has the better grade: Kardashian's husband (Odom) or current boyfriend (Harden)?
