Is a big penis more attractive than a mid-size model? What about a small penis? The long and the short of it is that when it comes to what makes a pretty penis beautiful, dimensions matter. One study found that women rated overall genital appearance and manicured pubic hair as the most important factors in determining what makes a pretty penis. Credit the manscaping movement for being more than just hype and marketing.
Bigger is better—at least when it comes to a woman's penis preferences, a new study says.
What penis size do women prefer?
The findings suggest that female choice may have driven the evolution of larger penises in humans. Past psychology studies that have asked women about their preferences for penis size have produced mixed opinions, with some saying they don't care about the size, while others say they prefer larger penises.
But those women may have felt pressured to say the politically correct thing: That size doesn't matter, said study leader Brian Mautza biologist at the University of Ottawa, Canada. So his team set up an experiment in which Australian women—averaging 26 years old—each looked at 53 life-size images of various computer-generated male silhouettes projected onto a screen.
The gray, homogenous-looking men had different heights, shoulder-to-hip ratios or body shapesand flaccid-penis lengths. In past studies, women have generally perceived tall men with greater shoulder-to-hip ratios as more alluring, making these factors important in how a woman judges attractiveness.
The women in the current study were then asked to rate the men on an attractiveness scale ofwith 1 being least attractive and 7 being most attractive.
Size matters, but not as much as men think, studies say.
Although body shape was the most important factor in whether or not women rated a male shape as attractive or not, penis size also ificantly influenced attraction. However, the relationship wasn't necessarily linear—i. Read about the barnacle, which has the longest penis relative to body size in the animal kingdom. For example, the rate at which women rated the men as attractive fell when flaccid penises were longer than 2.
What's more, height was also a factor: "Tall guys with really large penises ended up being most attractive relative to other figures," Mautz said. It's not totally clear why women prefer bigger penises, but studies have shown that women prefer larger sizes because they can increase sexual satisfaction, Mautz said. Since early humans didn't wear clothes, male penises were obvious to women.
So if women chose their mates based on the size of their genitalia, it's possible that these decisions influenced the evolution of bigger penises, according to the study, which was published in the journal Proceedings of the National Academy of Sciences.
Explore an interactive of the human body. But evolutionary psychologist Gordon Gallup, Jr. For one, studies have shown that "the flaccid human penis is an imperfect indicator of the size of the erect penis," said Gallup, of the State University of New York at Albany, who was not involved in the study. Theoretically, women in the early days of human evolution would have seen most penises in a flaccid state. What's more, the show that women paid more attention to shoulder-and-hip ratios than penis size when rating an image as attractive, he said.
Gallup has done his own research on penis evolution, which he said has been shaped by a man's competition with other males to fertilize a woman's egg. Gallup's research has found that the penis's arrow-like shape is able to scoop rival male semen out of the female's reproductive tract. Also see "Sperm Works Best in the Winter. What's more, studies using models of human genitalia have shown that deeper thrusting displaces more semen from a woman's reproductive tract than shallow thrusting.
Therefore, "long penises may have also evolved to deposit semen in the deepest and more remote parts of the vagina to promote more effective sperm retention," he said. Whatever the reason for large penises, this field of study addresses a question that some will find humorous, study leader Mautz acknowledged. All rights reserved.
