Sexual arousal

Sexual arousal also sexual excitement is typically the arousal of sexual desire during or in anticipation of sexual activity. A number of physiological responses occur in the body and mind as preparation for sexual intercourse and continue during it. Male arousal will lead to an erection , and in female arousal the body's response is engorged sexual tissues such as nipples , vulva , clitoris , vaginal walls and vaginal lubrication. Mental stimuli and physical stimuli such as touch, and the internal fluctuation of hormones , can influence sexual arousal. Sexual arousal has several stages and may not lead to any actual sexual activity, beyond a mental arousal and the physiological changes that accompany it.

Going by a recent story in the Daily Beast, it would seem so. But a closer look at both the article and the research it cites reveals that the problem isn't with deceptive women—it's with how the science of women's arousal is conducted and interpreted. The Daily Beast story covers research that found that, while straight women say they're not aroused by lesbian pornography or wildlife documentaries showing mating, measurements of those women's vaginas suggest otherwise. The research Cormier reports on traditionally measures blood flow to men's penises and to women's vaginas as a mark of study volunteers' physical arousal in response to images and videos. The study found that men's physical measures typically follow what they say they find arousing—in other words, according to these studies, men's mental and physical arousal match—while women's don't.
