New research reveals the ‘most attractive penis’ – according to straight women and men

A new study has revealed the ‘ideal’ shape and length of a penis.

Researchers asked 1,029 men and women to examine 14 computer-generated images of erect, circumcised penises.

Participants rated an aspect of the penis in each image, such as the shaft or the cylindrical structure from the base to the head, or the head of the penis.

The findings allowed researchers at the University of California, Riverside, to construct the “perfect” penis.

In the study, participants were shown a pair of images in which one aspect of the penis had been digitally altered, such as the length of the shaft or the shape of the head.

They were asked to indicate which they preferred, with researchers analyzing the answers to reveal which feature was ‘best’ and to construct the ideal penis.

This was repeated seven times for participants – who were on average 30 to 39 years old – to assess seven different characteristics of the penis.

Overall, the majority of participants said they preferred a penis with a longer shaft, a more prominent corona (the rounded ridge at the base of the glans), and a slightly smaller head.

When viewing the penis from the side, participants also said they preferred a head that ran down from the end of the shaft and was slightly angled at the base.

On average, participants said they liked the same width across the entire organ rather than a penis that grew larger at the base.

The researchers didn’t ask participants to rate the overall length of the penises to determine “best,” but previous studies on ideal length have concluded that 6 inches when erect is most preferred.

For comparison: a meta-analysis involving more than a thousand men – mainly in Europe, America and Asia – suggested that the average length of the erect penis was 15.1 to 17.5 centimeters.

The researchers also found variation in penis preferences based on age and sexual orientation.

They emphasized that their results suggested that penis preference was intensely personal (default).

Older adults were 25 percent less likely to prefer a larger ridge at the base of the penis, compared to younger individuals, and 18.4 percent less likely to prefer a head that was angled at the base.

Heterosexual adults – who made up the majority in the study – were 65 percent more likely to prefer a larger corona.

The results also showed significant differences in penis preferences between medical professionals, who made up half of the participants, and others, which the scientists said could be related to their training backgrounds.

The researchers said they conducted the study to provide doctors with a guide to reconstructing penises after catastrophic injuries.

Summarizing the results, Dr. Justin Cordero, a urologist, and the others in the study wrote: ‘The ideal phallic aesthetic varies by individual, and there were statistically significant preferences based on age… and sexual orientation.

‘This study can serve as a guideline for phalloplasty for patients and gender-affirming surgeons.’

In the study, published in the journal UrologyResearchers said penis preferences could be determined by viewing pornography.

The study recruited participants through surveys distributed on Craigslist, Amazon and Reddit.

Of the participants, the majority – 539 people – were heterosexual, but the remaining 370 were homosexual, bisexual or another sexuality.

By gender, most participants were male (440 people) or female (334 people).

The paper also included 92 adults who were transgender males – 10 percent of the total – and 25 transgender females – three percent of the total.
