(PHOENIX) -- Though accused murderer Jodi Arias said she sometimes felt "like a prostitute" at the hands of her ex-boyfriend, Travis Alexander, she admitted on Tuesday that she often enjoyed their sex life and even suggested sex acts they could try.
Prosecutor Juan Martinez, after a day of aggressive questioning and bickering with Arias, asked her about her own suggestions for her sex life with Alexander, including a phone conversation in which she suggested using sexual lubricant.
Arias, 32, is accused of killing Alexander, but claims it was in self-defense.
"You introduced KY Jelly into the relationship to make it more sexually enjoyable, right? When we're talking about the level of experimentation, it looks like both of you were experimenting together sexually. So when we hear things like, 'I felt like a prostitute,' that's not exactly true, is it?" Martinez said.
"It was often mutual," Arias said. "I didn't feel like a prostitute during, just after."
Martinez showed the jury a text message Arias sent offering to perform oral sex on Alexander, comparing it to a statement she made on direct testimony saying that she once felt like a prostitute when Alexander tossed a piece of chocolate at her and walked away without a word after she performed oral sex.
"How is it you can say you 'felt like a prostitute' when you're moving the relationship ahead like this?" Martinez asked. "The act itself is the same thing, and here you're requesting it. The geography is different, but that aside, isn't it the same act? And you're requesting it?"
"When he (ejaculated) and left afterward I felt like a prostitute. When we mutually went through things together I didn't," she said.
Arias also admitted that she sent Alexander a topless photo of herself after he sent her photos of his penis, and that she only did it after she had her breasts enhanced surgically.
The testimony came as Martinez continued his efforts to discredit Arias' testimony on the stand, including her statements that she often succumbed to Alexander's sexual fantasies so she wouldn't hurt his feelings. Martinez has focused on portraying Arias as a liar for much of his direct examination.
Arias is charged with murder for killing Alexander at his home in Mesa, Ariz., in June 2008. She claims she killed him in self defense and that he had been increasingly violent and sexually demanding in the months before the confrontation. She also claimed he was interested in young boys.
The prosecution claims she killed him in a jealous rage. She could face the death penalty if convicted of first degree murder.
