There has been a lot of scientific and cultural interest lately in differences in the between men and women. For example, my colleague Dr. Meredith Chivers has been publishing some fascinating research showing major differences in the ways in which men and women experience sexual attractions. She has found that men are fairly specific in what turns them on sexually, whereas women in general have more flexibility. Men who identify as heterosexual become aroused when watching films of women but not men. Gay men tended to be aroused by films of men. This is very different with the women in her research. No matter how they identified in terms of their , they were more likely to show the same pattern of arousal to men, women, and both. Her research was featured in a New York Times Magazine cover story.

To help understand differences in sexual attractions and bisexuality in men and women, I sat down with Dr. Brian Dodge at a recent conference. As a Research Scientist and Associate Director of the Indiana University Center for Sexual Health Promotion, Dr. Dodge has conducted fascinating research on male sexuality, particularly bisexuality. In the video below he answers my question, "is bisexuality the same thing in men and women?"
