There are few men who haven’t wondered at least once how they measure up in the bedroom.
Now the NHS has released a package of useful information about sexual health, and one key fact buried in there is the true average size of the great Brit penis.
Researchers at University College London measured the penises of 104 men to figure out just what we have down there.
They included males of all ages, from teenagers to pensioners.
The average penis length in this group was 5.1in (13cm) when “soft and gently stretched”, the research said.
They also noted that some penises are “growers” while others were more immediate “showers”.
NHS research revealed that men with penises at shorter end of the scale were more likely to see a bigger increase in length when they achieve an erection.
Research based on the penis measurements of 2,770 men found shorter penises increased by as much as 86% when erect.
Penises that were bigger to start with were only likely to increase in size by about 47%.
The average penis size can vary from 5in to 7in and the NHS points out that “you cannot make your penis larger or smaller with exercises or medication”.
But the researchers debunked the old wives’ – or old husbands’ – tale about a link between penis length and shoe size.
The health service added that there is significant variation in the angle of an erect penis, pointing out that “each penis is unique”.
The NHS report says: “Most men’s view about their penis is formed during childhood.
“Growing up, they may see the penis of an older brother, friend or their father and mentally compare this to their own.
“Fears and anxiety about penis size may also arise after taunts from other people during adolescence or following remarks from a sexual partner.
“However, men often have the wrong perspective on their penis.”
“To see your penis as other people would, look at yourself undressed in front of a full-length mirror.
“The penis looks longer and larger than when observed from above.”
To get a precise measurement of your own penis, assuming you have one, the NHS recommends you to do it when you have an erection.
It is standard to measure the penis on the top side, from the base to the tip.
There’s also a warning on the NHS’s penis facts site that you can break it if you’re not careful. So be careful!
