What won't surprise you is the men who were taller and had more muscular physiques scored even higher in the test, according to the study published in the Proceedings of the National Academy of Sciences.
It found that women indeed prefer larger penises - certainly up to 5.1 inches (13cm) flaccid.
Interestingly, beyond 2.99 inches, the extra attractiveness points per length started to wane.
Why is this good news? Well, according to a 2001 Italian study, that particular length was considered 'below average'.
The results suggested that a larger penis helped taller men the most, which maybe has something to do with looking in proportion.
Sadly larger genitals didn't seem to help the shorter men pictured in the study, according to the Huffington Post.
Scientists reckon this could help explain why humans have abnormally large genitals compared to their average size, when compared to gorillas and other large primates.
Despite weighing 400lbs, gorillas only have erections measuring 1.5 inches on average - whereas this study found that the average size for male humans appears to be just over 5 inches.
Evolutionary biologists believe this could be because females were drawn to males with larger genitals in the days before clothes arrived on the scene - leading to big penis genes being passed down the generations.
