What if We Can Use Mathematical Equations in Understanding Sex and Relationships

When sex is on your mind (and let’s face it, it constantly is), it’s not common for it to share the same thoughtspace as a mathematical equation. But who said it shouldn’t?


The most complex equation is understanding sex… worst relationships. But what if we can use mathematical equations to solve this great mystery?

Mathematician Clio Cresswell, who has also been cited as one of the sexiest scientists alive, has made it her life’s work to relate mathematics to sex by essentially boiling down fluid emotions into static and complicated equation in an effort to predict sexual behaviour.

Basically, she’s using math to tell you why you got dumped. Or why you keep lying about how many women you’ve slept with. Or why you have an STD (okay, maybe not that – go see a doctor).

In a recent TedxSydney talk, Cresswell outline some of her findings:

1. Cyclic Dynamics in Romantic Relationships

Ever wondered why you and that manic pixie dream girl didn’t work out? Apparently, there’s an equation for that. Cresswell cited a study that outlined which factors and personality traits influence relationship longevity – and no, it’s not how good you are at doing the alphabet with your tongue.

2. Men and women report number of sexual partners differently

Mathematicians have determined that women, when asked how many men they’ve slept with, tend to enumerate, while men approximate. And when you enumerate, you underestimate, and when you approximate, you tend to overestimate. Fun fact: 80% of men’s results were divisible by 5 – take that how you will.

3. Women’s (and Men’s!) Hormone Equations

Mathematicians looked at how the female body knew how a month has passed between cycles and how these cycles affect their moods. The entire male populace has been criticizing women’s hormones for centuries, so it’s just fair to look at men’s hormones as well. And will you look at that, men’s are much more complicated.

4. Thinking about sex makes your brain better

Studies show that big, philosophical ideas like love help the brain process big-picture problems, while the gritty things like sex help people dive into the details and analysis of problems. Easy as that.

According to Cresswell, mathematics lies at the roots of humanity – much like sex. So the next time anyone tells you you’re weird for being too into math, just ignore them. You’re the sexiest person in town.
