Testicle Size Matters & 10 More Bizarre Facts About Cheating

Hair color? Deep Voices? Facebook? See what else is leading to adultery, according to science.

Size does matter … just not the size of what you think.

A new study claims that women are more likely to cheat on their man if he has big balls. (Yep, you read that right.) Researchers from the University of Oslo studied primates — bonobos, specifically — and they found that a female is more likely to have other sexual relationships if their mate has large testicles.


And it doesn't stop with monkeys. "In one type of grasshopper, the testicles occupy half their body mass. The testicles are even larger in sea urchins. They spawn directly into the ocean. To increase the chance of fertilizing an egg, the sea urchin is a huge testicle with a little shell around it."

The testicles of humans are one and a half times larger than those of gorillas, the team said. They claim this shows that we are an unfaithful race by nature.

Personally, I'd like to know why they decided to study monkeys, bugs and sea urchins to determine human behavior, but I digress. The point is that you'd probably have to have big balls to interject yourself into someone else's relationship. (Bro code, guys?)

Still curious about other bizarre facts found from cheating studies? Here are 10 research-proven factoids that had us do a double-take:

1. Facebook: Is An Affair One Click Away?
They say that Facebook can figure out how long your relationship will last … but maybe, the reason is because they are the culprit? A new study published in the journal of Cyberpsychology, Behavior, and Social Networking suggests that the social networking site leads users to re-connect with old flings, which in turn is leading to more affairs, breakups or divorces.

2. The French Are Big-Time Cheaters
They say that the French make the best lovers in the world, but that doesn't make it true love. If you believe the findings from this study, probably not. A poll found that a majority of men and a third of women admitted to cheat on their partners, indicating that infidelity is on the rise in France among both sexes. Infidelity has been on the rise in that country since the 1970s, when only around 19 percent admitted to cheating (everything from kissing to swapping naughty texts).

3. A Slap For An Affair?
An eye for an eye … or rather, a slap for an affair. As part of the Crime Survey For England and Wales, ten percent of the total 38,500 people surveyed agreed that "hitting or slapping" your unfaithful partner is appropriate for a betrayal of the heart. Yikes.

4. Cheaters Love Chain Restaurants
Suspect that your partner is cheating? The first place you might want to scope out is a chain like Taco Bell. (You quiero ... an affair?) The infamous extra-marital affair dating website Ashley Madison asked over 40,000 cheaters where they loved to wine and dine in secret, and thus, revealed the top 10 dining destinations to have an affair. Among them? Red Lobster, Outback Steakhouse, Chili's and P.F. Chang's.

5. Cheaters Also Love Shopping (At Banana Republic, Among Others)
This isn't exactly great PR for Banana Republic. After delving into the wine-and-dine habits of the unfaithful, AshleyMadison.com also scoped out the most popular shopping outlets. After polling 50,000+ women, more than a third admitted spending double on keeping up their looks for their secret lover. In addition, 27 percent said they even have a secret credit card to keep their financial infidelity under wraps. So what are some of the other popular stores for cheaters? J. Crew, Macy's, Ann Taylor and H&M all ranked high on the list. (And here you thought she was just getting a new suit jacket for work.) 

6. Faking the Big O Is A Big Red Flag
If your partner is faking it in bed ... watch out. It could be a bad sign that he or she is getting action in a bedroom somewhere else. One study claims that both men and women who faked orgasms were far more likely to be unfaithful. KEEP READING ...
