Khloe Kardashian’s ex, Lamar Odom reveals he is addicted to s*x and has slept with over 2,000 women

Lamar Odom is opening up for the first time about a crippling s-x and drug addiction that nearly cost him his life. In his new memoir, Darkness to Light exclusively excerpted in PEOPLE the NBA champion writes,

“I have been obsessed with s-x for as long as I can remember.” I am a s-x addict,” writes Odom, who was married to Khloé Kardashian for four years before they split in 2013.

The 39-year-old reveals that he has had s-x with more than 2,000 women.

“There were too many strippers to count,” he writes. “It wasn’t a big deal, but often I would pay them. I never thought less of them.”

Odom also reveals that he cheated on Kardashian throughout their marriage; she eventually discovered the infidelities.

“I was shocked and embarrassed,” he tells PEOPLE in an exclusive interview.

“I wanted to take it back, but you can’t. [I] wanted to hide it. But that sick sin was hard for me to hide … I had a problem.”

Continues Odom: “[I] ran out of porn to watch! That’s how you know when you are going a little overboard.”

Odom’s addiction to s-x was compounded by his addiction to drugs.

“S-x was a trigger for me to do drugs,” he tells PEOPLE. “Because you double up on [that] good feeling.”
