Ray J Book on Kim Kardashian Reveals Her Sex Life, History of Cheating on Men

In his new book entitled, Death of a Cheating Man: What Every Woman Must Know About Men Who Stray, Ray J goes on the record about his relationship with Kim Kardashian, revealing her history of cheating on men, their sex life in bed and her obsessive behavior.

Ray J, 31, spills the details about a woman he dated for over two years by the name of KK, and it appears to be no coincidence that the initials of the woman in the book, time frame of dating and secret details match up with 31-year-old Kardashian.

According to the tell-all, KK pursued Ray J while she was still married to music producer Damon Thomas before they divorced in 2004.

To be honest, the whole thing started off wrong, Ray J wrote. We'd known each other for a while before we dated and there was a mutual attraction, but she was married ... She let me know she wanted to get with me. She left her husband for me as soon as we started having sex and things between us got intense really fast. After that, I felt obligated to be with her.

Ray J also said the relationship was purely sexual with Kardashian, whom he made a sex tape with in 2003 that spread around the Internet four years later.

We were like animals; sexually free to try anything, and we did, Ray J wrote in the book released on Valentine's Day, ironically enough. For years KK and I had a great sex life. There was more to our relationship, but the majority of it was about our wild and extreme sexual chemistry. She was a straight freak who was down to do whatever, whenever and that seriously hypnotized me.

Kim Kardashian and Ray J reportedly also cheated on each other, leading to a tumultuous relationship of jealousy, going as far as taping each other's phones.

As far as sex, it was intense. It was a rollercoaster ride of fun and emotions and infidelity and lies from both ends. We were the same person; we lived the same life; we lied the same; we cheated the same. We were the same person in different forms, but at the end of the day, it clashed, he wrote.

Ray J also wrote that at times, KK locked him in an emotional world with behavior perceived by outsiders as slightly obsessive.

I was hypnotized. Waking up in the morning with toothpaste already on your toothbrush, a warm towel already ready to go to wash your face. The perks of being with a woman like that could really trap you into an emotional world that it's hard to get out of, he wrote.

But the couple eventually split in the summer of 2006, which Ray J believes was for the good.

The relationship with KK ended because we just felt like we were friends. We were honest with each other, but as far as our commitment as a one-on-one relationship, that just wasn't working, he said.

While the book exposes the woman in the relationship who is obviously Kardashian, Ray J said it is by no mean's a tell-all.

I don't mention any names in the book. I kinda leave it open. I didn't want to make it a tell-all. I wanted to make it a book about revelation about the things that I've done and things that I want to do in the future, he told The Insider.
