Inchworm, inchworm

From today's Telegraph:

Although six inches has long been the accepted “norm” for the length of a manhood, the average is actually almost a full inch smaller, research reveals.

Length
Analysis of 17 studies involving more than 15,500 men revealed that the average length of an erect penis is 5.16 inches (13.12 centimetres) and 3.6 inches (9.16cm) when flaccid.

Girth
The study found the average penis had a girth of 4.59 inches (11.66 cm) when erect, and 3.66 inches (9.31cm) when flaccid.

Range
The scale the scientists used tracks a range of penis lengths and girths, with measurements of length when erect ranging from 1.9 inches (4.8cm) to 8.3 inches (21.2cm).

Psychiatrists who carried out the study said they hope the findings could help men suffering from “small penis anxiety” because of concern that they do not match up to the norm.

The study was led by the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London and South London and Maudsley NHS Foundation Trust (SLaM).

The study did not draw any conclusions about differences in penis sizes across different races.

One study in 2013 suggested that penis length and girth was greatest in sub-Saharan Africans, intermediate in Caucasians and smallest in East Asians.

However, those findings were based on studies which did not meet the criteria of the new research, which was largely made up of Caucasian and Middle Eastern men.

The new analysis suggests age makes little difference, although some of the studies found the flaccid lengths and circumferences of the penises of older men were greater than those of younger men.

Suddenly, I'm not so upset about getting old...
