It turns out that the average penis size for men across the board is getting bigger. Together, condom-brand SKYN and King’s College London came together to do some super-hard work and compiled the sizes of 15,521 men’s penises. They found that the average size of a man’s penis between the ages of 18-34 is 6.1. While the national average for the UK in 2016 was 5.16.
Don’t get too excited. The research is pretty flawed. Researches forewent actual measurements and had participants self-measure and send in their results.
A report found that men “…almost always really lie about how big their manhood is.”
