It's a gimmick. She isn't promoting nudism. She wants her clients aroused. According to her website all of her clients are men. She is that same thing as a prostitute or porn star selling her body, sex sells. She is the same as any other webcam model, but she is just hiding under the thin veiled guise of therapy.
From her webpage:
Price: $200 for an hour-long webcam session
Q: How does a session work?
Different clients require/desire different things, but generally you decide if you’d like to start with a text chat and a one-way cam (you can see me but I can’t see you) or a voice chat and two-way cam (we can both see and hear each other).
Q: What happens during the sessions?
You and I talk about whatever you want to talk about, and, should you wish it, I (and/or you) get naked in the course of that conversation.
Q: Am I allowed to make special requests?
Yes. If you want me to wear something special, ask me in advance and it can be arranged. If you want me to undress in a certain way, that can also be happen. And if you want to see me from a certain angle, or you want me to do or say something specific, simply ask. I do have my limits and only do what I consider to be therapeutically relevant to your progress, but I am also very open minded :-)
Q: Can I masturbate during my session?
Yes.
Q: Do you accept health insurance plans?
Currently no, but maybe some day!
Q: What are your credentials?
First off, I am not a licensed psycho-therapist. In fact, I can’t be licensed because my techniques are considered unethical by state licensure boards. However, I have studied psychology, human sexuality, and social biology, and I have helped hundreds of people, many of whom say that Naked Therapy has made a huge difference in their lives. Further, I consider myself highly skilled at talking, listening, and counseling while also being arousing :-)
