Some are watching porn, as our sex columnist Ian Kerner pointed out in a recent column.But what women are viewing and reading is usually not what men are searching for, according to a new book on the subject.'It's all free, easy to access, available within seconds, 24 hours a day, seven days a week,' she said.But she added: 'In some porn users, the response to dopamine is dropping so low that they can't achieve an erection without constant hits of dopamine via the internet.' Many were initially shocked, she said, when they discovered their sensitivity was declining 'toward normal sex'.'People who exercise self-control in this area and make a point of steering clear of pornography and sexual imagery in all its forms are not the repressive killjoys they are often taken to be,' he added.Men everywhere have probably wondered for thousands of years: What turns women on?But she said that while recovering, addicts were likely to experience a temporary loss of libido as well as 'insomnia, irritability, panic, despair, concentration problems, and even flu-like symptoms'.
A 'paradoxical effect' is created whereby with each new thrill, or 'dopamine spike', the brain loses its ability to respond to dopamine signals, meaning that porn-users demand increasingly extreme experiences to become sexually aroused.'Today's users can force its release by watching porn in multiple windows, searching endlessly, fast-forwarding to the bits they find hottest, switching to live sex chat, viewing constant novelty, firing up their mirror neurons with video action and cam-2-cam, or escalating to extreme genres and anxiety-producing material.For men, the cues are predominantly visual, and aimed at the partner; they often enjoy seeing women orgasm, which may be one of the reasons why so many women fake.In "A Billion Wicked Thoughts," released Thursday, neuroscientists Ogi Ogas and Sai Gaddam combine web searches, personal search histories, websites, and classified ads with insights from brain science to discover precisely how different women are from men.Just like we're all born with taste cues - sweet, salty, savory, spicy, bitter - men and women's brains are wired with sexual cues, Ogas said.In the age of the Internet, it's possible to find out.
