A new study was released today that shows and grows the belief that size does matter, evolutionarily speaking. But does it? Of all primates, humans have the largest penis, gorillas have the smallest. And science wondered why that would be. Now, we have an idea. The ladies pick their mates prior to having sex with them. The researchers showed women computer animated male figures accounting for traits normally associated with male attractiveness, like height and shoulder to hip ratio. But they added in flaccid penis size. Everyone finds taller men more attractive. It's just generally accepted. But when paired with the ideal body ratio and a larger penis size, attractiveness increased. In a nutshell, the results found that flaccid penis size did affect levels of attraction for women. Taller dudes with larger flaccid penises were considered more attractive. The scientists wanted to know, why are our penises larger relative to the size than other primates, and if females can affect the evolution of the male member in a species. Yes, in a nutshell. Female sexual selection can influence the size of a phallus over time. Girl power. Simply put, before we started wearing clothes 170,000 years ago, the females of our species would mate with males who had larger flaccid penises. As the selection continued, generation over generation, human penises gradually got larger. It seems like a win-win to me. Guys, this is important. Flaccid penises range in size. And if you're really concerned about the size of your member, you're probably thinking of it when it's erect. The average erect penis is around 5 1/2 inches, perhaps because of evolution cultivated a phallus that best fit with the size of the vagina, which is about four inches. But this study only tested flaccid penises, not erect ones. The Kinsey Institute points out that the averages for flaccid penises are like one to four inches, whereas erect is between five and seven, the smaller flaccid penises increasing in size way more than the larger. Why should we evolutionarily look for size to matter? A study published in The Journal of Sexual Medicine indicates that women report having more frequent orgasms with larger penises. But the obsession over size shrinks when you look at a myriad of studies that show the best predictor of sexual satisfaction is enjoying the company of the person attached to the penis, not the actual penis attached to the person. In worthwhile relationships and attachments, confidence and attraction wins over big dongs every time. For me, the study seems to miss the idea surrounding forcible mate selection in the history of our evolution. Were females hundreds of thousands of years ago free to select mates as they wished?
