Women aroused as quickly as men

Researchers using night vision infrared cameras on test subjects found out that women aroused as quickly as men. From LiveScience:

Thermal imaging technology, which uses cameras that detect heat given off by different objects, is a relatively non-invasive way of measuring the time it takes a person to reach peak arousal.

So researchers focused the cameras on the genitals of test subjects while the subjects watched footage of pornography, travel shows and horror clips. This provided measurements of heat from both the sexually aroused and from whatever arousal or lack of it was spurred by the other programming.

"Comparing sexual arousal between men and women, we see that there is no difference in the amount of time it takes healthy young men and women to reach peak arousal," said Irv Binik, a McGill University psychology professor and founder and director of the Sex and Couple Therapy Service of Royal Victoria Hospital.
