In Greek mythology, Tiresias was a blind prophet, the most famous soothsayer of ancient Greece. Having angered a goddess, he was transformed into a woman as punishment. Seven years later, Tiresias was able to reverse the curse, and became male once again. Since Tiresias possessed the knowledge of being both a man and woman, he was revered by even the gods.

Today's guest, Professor Ogi Ogas, is one of the first in history to see both male and female's secret sexual desires clearly and to extrapolate scientific explanations for them. The discoveries of Prof. Ogas and his academic partner, Sai Gaddam, came out of their background in cognitive neuroscience, and was bolstered by their brilliant use of the internet's empirical data. This work culminated in their groundbreaking book "A Billion Wicked Thoughts."

While working for years in the porn business, I had an intuitive idea about what men were into, but I never had the science to back it up. Three years ago, I read Ogi's Wall Street Journal article about his ingenious research, and was awed by it. I sent him an email and, to my delight, he wrote me back. We became fast friends.
