A good sex life is in your hands.
A new study on the relationship between sex, love and upper body strength suggests that first impressions — sealed with a handshake — can reveal key details about your personal life.
The study, published in Evolution and Human Behavior, reviewed people’s grip strength, a common measure of upper body strength, and survey responses about sexual behavior.
The researchers at Washington State University analyzed data from 4,316 US adults obtained from the 2013–2014 National Health and Nutrition Examination Survey to discover their results.
Stronger men are more likely to be in long-term relationships and have more sexual partners compared to their peers, the study found.
Meanwhile, stronger women are more likely to have a longer list of sexual partners compared to their weaker peers. However, strength did not appear to influence the length of women’s past relationships.
Experts have long believed men’s strength to be an evolutionary marker as men competed against each other for access to mates — survival of the fittest.
Another theory claims that stronger men were more desirable as partners because they could hunt for meat as the women cared for the children, especially during pregnancy and infancy.
“People have assumptions about men’s sexual behavior and how that’s related to evolution,” lead author and anthropologist Caroline Smith said in a statement to Phys.org.
“Besides acquiring more sexual partners, establishing long-term relationships was likely also important for men in evolutionary history.”
However, why women’s strength impacts their sex life remains mostly a mystery.
“Men are stronger than women, on average, and men report more lifetime partners than women, but men and women are on the same regression line,” WSU evolutionary anthropologist Ed Hagen said.
“Regardless of whether they’re males or females, stronger individuals have more lifetime sexual partners. That was a surprising finding and somewhat contrary to the sexual selection hypothesis.”
A man’s hands can likely determine more than just their sexual history.
A new app claims to be able to deliver an accurate prediction of a man’s penis size and shape and your potential sexual compatibility using just a photo of their hand.
Brand strategist Triin Randloo recently released SizeHim, a titillating new tool to give you a hand.
Once users upload a photo of their hand and the hand of their potential partner, the site’s calculations will then predict which of the seven penis types — curved UP Banana/C-Shape, bender, cucumber, big shaft, big head, mushroom or pencil — the person likely has, the odds of your physical sexual compatibility and even give suggestions of what sexual positions would feel best with this sexy combo.
The hand really can tell us a lot, Randloo and her curious crew confirmed — when a couple’s proportions were similar, there is a higher likelihood of a physical match, which increases the odds of great sex.
