Researchers have delved deep into the bedrooms of US couples in a massive study to find out what turns them on.
The survey of 5,865 people was meant to reveal how men and women viewed sex — and how Americans have sexually evolved since the groundbreaking work of researcher Alfred Kinsey more than 60 years ago, the New York Post reported. In the latest study, the researchers from Indiana University found 85 percent of men said their female partners reached orgasm the last time they had sex — while only 64 percent of women said the same.
“We certainly know some women do fake it,” Debra Lynne Herbenick, a research scientist at the university’s School of Public Health, said. "This shows this is one area that the sexes can do a better job of — communicating,” she said.
The rise of oral sex could be the single biggest change in American sexuality over the past 60 years.
The survey showed 91 percent of men said they had received oral sex from a woman, compared with 30 percent in Kinsey’s study. In Kinsey’s day, 25 percent of women had received oral sex from a man, while 88 percent have now experienced it.
“What really changed was the sexual revolution and the dawn of the HIV epidemic,” Herbenick said. “Americans expanded their sexual repertoire and found that there are many, many ways to be sexual, safely, with others,” she added.
The findings will be highlighted Sunday on the Discovery Channel’s Sex in America, part of the network’s documentary series Curiosity.
