A study that appeared in the peer-reviewed scientific journal Proceedings of the National Academy of Sciences (PNAS) discovered that the respondents (women) rated tall men with large penises as the type of male they found sexually attractive. Even though there were short males with large genitalia who were also presented to the women as well, they were not categorized as attractive.
The study results “directly contradict claims that penis size is unimportant to most females” and also hints at why human males tend to have relatively larger genitalia when compared to other primates, the study said.
According to evolutionary principles, the researchers of the study state, “Our results show that female mate choice could have played a role in the evolution of the relatively large human male penis,” the authors wrote. The scientists also deduced that the women may have looked at the endowed men as someone who could adequately sire a healthy child.
The study, however, did not get in to the racial background of men and whether that may affect penis size.
