UCLA researchers say they've got the first physical evidence to support the notion that some people's brains are wired for sex, reports the Los Angeles Daily News. In the study, they asked men and women how many sexual partners they've had, and they also showed them images that ranged from non-sexual to slightly sexual (like kissing) to explicitly sexual. The more partners a person had, the more likely their brains were to light up on EEGs when looking at those last two categories, reports Medical Xpress.
The researchers weren't surprised that their subjects reacted to graphic images, but they were intrigued to find the correlation with the G-rated images, too. “If your brain responds very strongly even to very tame pictures of sex, then you seem to be easily sexually excited in the real world, too,” says lead researcher Nicole Prause. The results could help those naturally inclined toward the risque to be safer, she says, as per Time. “Being aware that if you are going out, and there is the possibility of having a new partner, and thinking about ways to not get too excited may sound silly, but managing that rather than ignoring it may help with better ways to control risky sexual behavior."
