So generally speaking, humans have gotten bigger over time. Now science is indicating that trend may apply below the belt, too.

A recent report in the Sun indicates that a 2016 study conducted in part by King’s College London found that the average erect penis measured just a bit over 5 inches in length. Not too shabby, right? Adding to that finding is condom maker SKYN, who in 2017 revealed that this size is significantly bigger for millennials. Their investigation found that the average penis size for 18- to 34-year-olds is around 6.1 inches when fully aroused.

So why did the studies have two different outcomes? Because most men lie about wiener size, duh.

The King’s College survey had a larger sampling size, 15,521 men. SKYN’s survey result was reportedly taken from 3,037 sexually active adults and the results were gathered from forms filled out online. 

Also noted by the Sun, it’s very much so possible that the dudes questioned were straight-up lying about their d-size. The larger King’s College sample tends to support this conclusion. 

The real question here is: Does size really matter to women? According to an Australian study done about a year ago, size does matter—but only as part of the overall package. Pun intended. Women also notice things like shoulder width and torso size, and let’s face it, money plays a role in overall attractiveness, too. In the end, in bed, quality usually always trumps quantity. So just start practicing, quit worrying and have yourselves a ball. So to speak.
