Our knowledge of sex comes from the uncomfortable “birds and the bees” talk with our parents, sex ed, and high school hallways. Whether you’re a Don Jon or a bombshell, chances are you have some preconceived notions about sex based on anecdotes over the years. These sex myths are based on a numbers game, where penis size, frequency of masturbation, and sex, among many other beliefs are severely skewed.

Wrongfully, these common myths have led to a glorified model of what sex should be like and have therefore positioned themselves as the “norm.” There is a wide range of sexual “accomplishments” and a distorted view of where the average person should fall on this sex spectrum. Science has proven time and again it is the quality, not the quantity, of sex that makes it pleasurable for both partners.

A 2013 study published in the journal Proceedings of the National Academy of Sciences found it is not penis size but the person attached to the penis that makes a difference. Researchers asked women to rate the attractiveness of males based on computer-generated images of different body types and penis sizes. Although taller and fitter men were much more desirable, a flaccid penis played a role in their perceived attractiveness, meaning a penis in proportion with the male body is much more desirable. Confidence, personality, and attraction are strong predictors of sexual satisfaction, and tend to weigh far higher than disproportionate penis size.

It’s time to put the penis size myth to rest, and other prominent sex myths exposed by the Greek organization The Institute for the Study of Urologic Diseases (ISUD), that may actually be ruining your love life.
