I chose my words very carefully... chosing "most" instead of "all" was clearly the right thing to do.
Although the "Christian" polls will tell you it's as high as 72% of men, better sources say it's closer to 54%...
http://www.pbs.org/wgbh/pages/frontline/shows/porn/special/why.htmlSome scientists believe that these differences have a biological basis. Evolutionary psychologists argue that ancestral men, to spread their genes, had much to gain from having sex with as many women as possible. In contrast, given the biological limitations on the number of children women could have and raise, they would benefit from being selective -- choosing mates with the best genes. Thus, men evolved a sexual psychology that makes sex with new women exciting both to imagine and to engage in, and this made men especially responsive to visual signals of sex. Porn, a largely visual medium, parades many youthful and attractive partners, and provides physical gratification without commitment or encumbering relationships. There are other social-historical explanations for the gender discrepancy, however, including the fact that, until recently, porn has not been created with the intention of appealing to women.
Does this mean that women are unresponsive to porn? Not exactly. Or, better, it depends. In his landmark interview studies in the 1940s and '50s, conducted with nearly 17,000 men and women, Alfred Kinsey and his colleagues found that 54 percent of men and only 12 percent of women reported being erotically aroused by seeing photographs, drawings, or paintings of nude people. Kinsey also found that during masturbation, men tend to fantasize visually while women generally don't do so. This does not mean, however, that porn does not elicit sexual arousal in women. Laboratory studies have shown that women almost invariantly show physical signs of sexual excitement to porn movies, as indicated by increased vaginal blood flow. Interestingly, this can happen even when women don't like the movies or when they experience negative emotions such as disgust or anger. And studies have also shown that women show stronger physical sexual responses to porn than to more romantic erotic stimuli.
