Sex Facts: Measuring Up

People have a ton of questions about how they match up against others in bed. Most of us are confident with one skill and question our effectiveness in other areas. We worry about being too big or too small, to dry or to wet, going to long or to fast. So, where do you stack up?

I have delved into the various academic and medical journals about sex and sexuality to give you, dear reader, some answers.

Does it matter if my girls are small?

Not particularly. In a study in the Journal of Sexual Behavior  by Dixon et al (2009) researchers tracked eye moments of men looking at photos of women. Men looked at the face and pelvis region first and looked at the breasts longest on each image. Attractiveness was correlated with hip to waist ratios (an hour glass figure was most desirable) and that breast size did not significantly influence judgement of attractiveness.

Is my vagina too big/too loose?

As with so much in medicine, since this involves women, it remains vastly understudied. There are very few studies describing the average dimensions of a healthy vagina. Almost all studies about vaginal function and size has to do with disease and dysfunction. Apparently while researchers are anxious to study dick size, measuring thousands upon thousands and comparing the results, very few care about vaginal size or function. So ladies, if someone ever tells you your vagina is “not normal” or “too small” or “too big,” tell them that is a nonsense statement since science chooses to remain in the dark about our lady bits!

Does it matter?

In a study by the National Institutes of Sexual Health, research on over 500 women found that the length of the vaginal canal did not predict sexual satisfaction.

Does my dick measure up?

Every man wonders about dick size. Most men worry about being small in comparison to others. Many scientists are apparently anxious to grab the members of other men, measure them, and see how everyone compares. Science is literally a dick measuring contest!  But how does your little dude compare with his peers?

Veale et al (2014) compiled metadata about penis size from a large number of studies. To be inlcuded in the metadata, the studies had to meet significant requirements for number of participants, use of the five Kinsey measurements for penis size, and reliability and validity. Some of their findings are below:

The measurements below are the 50th percentile measurement across studies with more than 15,000 participants:

Average length flaccid, not stretched = 3.228 inches

Average length flaccid, stretched = 4.722 inches

Average length erect = 4.75 inches

Girth, flaccid = 3.54 inches

Girth, erect = 4.33 inches

In an article by Boegart and Hershberger in the Archives of Sexual Behavior, researchers measured length and width of more than 5,000 men. They found on average, heterosexual men have larger penises than homosexual men. They suggest a number of reasons, including hormonal differences, that could account for this.

But does it really matter?
