Could it be that penises are getting longer?

It might not be the most burning question keeping you awake at night (if it is burning, go see a doctor), but science is still important, right?

The average penis size is 6.1 inches when fully aroused, according to a survey of millennials by the makers of SKYN condoms Ansell.

But a study from 2015 found that the average length then was 5.16 inches when erect. Almost an inch shorter.

And research in 2013 found the average length to be 5.6 inches.

And another study, in 2012, found that the average British penis reached 5.5 inches.

Before you go around telling everyone penises are getting bigger: a study titled "Am I Normal?" from King's College London and the NHS found the average length to be 6.3 inches in July 2016.

So that bucks the trend.
