A new scientific study by Australian National University researchers showed that penis size directly correlates with a man’s attractiveness to women.

When 105 Canberra women were asked to asses 53 fully life-sized, 3D video images of naked men, they displayed a clear preference for penises in excess of 13 centimetres in their flaccid state reports Stuff.co.nz 

This, in case you’re starting to panic, is beyond the measurements of 95 per cent of men.

Professor Jennions, who is set to publish the research this week said: “I guess there are going to be a lot of guys out there with rulers today. Not that they don’t already know instantaneously,”

He added that one of the most surprising aspects of the study was it could not accommodate an end point at which women found any penis too large. “Our curve wasn’t going down at 13 centimetres  so we did not reach the most attractiveness in terms of size. The concept of a penis that was ‘too big’ was outside the range that we tested and we simply didn’t find an absolute maximum size, even though it strikes me that it is going to start to look ridiculous and actually quite painful.”

Professor Jennions said the study was a valid scientific question.

“Humans have slightly longer and notably thicker penises for their body size compared to other primates. It’s been suggested that before humans wore clothes, females used penis size as one of the deciding factors when choosing a mate. Until now there has been very little data to support that. Our results hint that humans might have larger penises because females in the past were more likely to mate with well-endowed males,” he said.

“We may debate whether a man is attractive when he has kind eyes or a good sense of humour, but now, at least, we know the truth.”
