Debra LaFave: I crossed the line that never should have been crossed.
She's a top contender for the title of "America's Most Notorious Schoolteacher."
In 2004, Debra Beasley-LaFave was arrested at the home of a middle school student, accused of
having sex with him at her apartment, in her car and in her classroom.
She was 23. He was 14.
Debra LaFave: He wanted it and, yeah, I gave it to him.
Matt Lauer: Weren't you scared to death he would tell someone?
Debra LaFave: Obviously, not, 'cause I did it again.
Matt Lauer: And again.
Debra LaFave: And again.
In her first-ever television interview, Debra LaFave says - behind the lurid details of the case, there was a deeply troubled young woman.
Matt Lauer: When you were 13-years-old, 8th grade, you were raped by someone you knew?
Debra LaFave: Uh, huh.
Debra says an early, abusive relationship with an older boy forever shaped her view of sex.
Debra LaFave: I kind of developed this idea, that it was my role...in order to make a man-guy-boy happy, I had to do my part, which was pleasing him in that way.
Debra also maintains that bipolar disorder affected what she did.
Debra LaFave: Symptoms of bipolar definitely contributed to my mind-frame.
Still, Debra says she does not blame anyone else for what happened.
Debra LaFave: I'm not trying to give excuses. All I'm being is truthful. I'm going to be the first person to say, 'Yes, it's my fault,' And I'm dealing with that.
