Rielle Hunter Says Sex with John Edwards Was Like a 'Rock Concert'

"Something happened internally with me. I responded... I have not experienced it or felt what was happening before. Ever. An intensity, like a rock concert. A lot of energy," Hunter told Cuomo, her first interview since Edwards' acquittal on charges of accepting illegal campaign contributions.

All this week Hunter has been very vocal about her six-year affair with the former presidential candidate, as she promotes her tell-all, "What Really Happened: John Edwards, Our Daughter, and Me," to be published June 26.

Defending her actions, Hunter insisted she's not a home wrecker and that Edwards' 11-year marriage to wife, Elizabeth, who died from breast cancer in 2010, was troubled before the affair began.

"Their marriage was ruined before I got there. Years before I got there," Hunter told Cuomo. She said Edwards told her he had had other mistresses -- that she was not the first.

Hunter also talks about their 4-year-old daughter, Quinn, and how she is speaking out now for Quinn's sake. "I feel for both my daughter and for all the kids involved, the full truth needs to be in the public domain," Rielle said. "Their father's not a demon and their mother's not a saint. And I'm not a home wrecker. We're real human beings. And there is a real dynamic that was going on, good and bad. And we all made mistakes."
