Gender makes a distinct difference on what parts are stared at the longest.
Take a look at the hotspot picture.
All users tested looked the image, but there was a distinct difference in focus between men and women.
Although both men and women looked at the image of George Brett when directed to find out information about his sport and position, men tend to focus on private anatomy as well as the face.
For the women, the face is the only place they viewed.
This difference doesn’t just occur with images of people.
Men tend to fixate more on areas of private anatomy on animals as well, as evidenced when users were directed to browse the American Kennel Club site.
Where men focus and where women do not. Ha!

Men looked at the female face much more than women, and both looked at the genitals comparably.
