He does, and she doesn't

She didn't have to tell Charlotte, because he did it. One week later, he walked in for his second appointment, looking noticeably perturbed.

"Hello, Jack, come on in." She led him into her office and he lay on the sofa. She sat down, and he immediately started talking.

"Okay so I did what you said, and you won't believe what happened. The first day, when I told her about it, she didn't call me Jackie at all. The second day she called me Jackie twice. The third day it was eleven times, and the fourth day it was something like fifty, and since then she... she hasn't called me Jack even once. It's only been Jackie."

"I see, and how did you feel these last few days, Jackie?"

"Well, it's a little weird because, well..." he hesitated, unsure, "there's also the sex. In the past three days we've had sex seventeen times."

"How often do you normally have sex?"

"Maybe twice a week. We had sex twice this morning before breakfast, and once more before I came here."

"You had sex before meeting me?"

"She said she wanted to have sex with her beloved Jackie one last time before he was taken away."

"That is surprising. When the two of you have sex, who is usually in charge?"

"I am, I guess. But not these last few days. Even when she had me gag her, hold her down and fuck her, it felt like she was in control."

"She had you gag her and hold her down?"

"Yeah, she had me cum in my boxers and then shove them in her mouth."

"And you still felt like she was in control for all of this?"

"Yeah, weird, huh?"
