Eventually, this turned into a legal case, and then a book: Therapist, by Ellen Plasil. You can find it used on amazon.com at very low prices. I'm not especially recommending the book, but the basic situation she describes did happen.
I heard about it when it was first going on, before Ellen realized she was being used and abused. I heard about it from one of Ellen's friends. I heard the arguments Dr. Leonard was using, arguments that a woman with a healthy sexual response would necessarily respond to HIM, since he was so damned psychologically healthy.
In fact, of course, he was not a paragon of psychological health. He was a twisted creep. But patients have a strong tendency to idealize their therapists, so many bought his claims to perfection. There's even a technical name for such idealization of therapists: positive transference.
What really disturbed me, when I was told of his arguments, was that it struck me as a total twisting of Objectivism's position on romantic love. He turned it into a defense of polyamory, with himself in a privileged alpha male position, a sultan with his worshipful harem. It all seemed wrong to me, but there wasn't much spelled out in Objectivism to prove it wrong.
My own bias was towards monogamy. So I began thinking about the issue seriously.
Obviously, in retrospect, the reason there wasn't much pro-monogamy stuff in Objectivism, is that the two main theorists, Rand and Branden, were practicing non-monogamy for years. But that was on the QT until Barbara Branden's book came out.
So that is part of the reason I eventually came to write a book that focuses in part on monogamy vs. polygamy.
Rhyme of the day:
Dr. Leonard settled the case
And fled New York to hide his face.
