There's new news about what gets women turned on -- and what gets them off, which always piques our interest.
There's no better person to explain these orgasmic breakthroughs than our special guest blogger Ian Kerner, author of "
She Comes First: The Thinking Man's Guide to Pleasuring a Woman," out in paperback for the first time this week.
In fact, check back early and often -- during our countdown to Valentine's Day, that holiest of holy get-it-on holidays, the sex doctor will be
in.
In fact, Kerner will be guest-blogging and offering his free advice -- including answers to your
most pressing sex questions -- all week. For now, he shares four things that put the "Oh!" in orgasm.
1. Your brain needs to turn off for your orgasm to turn on. Researchers in the Netherlands found that the key to getting a woman to the heights of orgasmic bliss is a deep sense of relaxation -- and a lack of anxiety. All in the name of science, researchers at the University of Groningen scanned the brains of women and men while they were manually stimulated to orgasm by their partners. The scans showed that, for women, the parts of the brain responsible for processing fear, anxiety and emotion slowed down the more aroused they became, producing a trance-like state when they climaxed. Says Dr. Gert Holstege of women's sexual wiring: "What this means is that deactivation, letting go of all fear and anxiety, might be the most important thing, even
necessary, to have an orgasm." Men's gray matter, on the other hand, showed far less change.
So, how you do turn off in order to turn on? More on that after the jump.
