How to read the numbers
Measured beats self-reported
When people report on themselves, sizes and times come out bigger. This site leads with figures where a clinician held the ruler or a couple held a stopwatch, and says so when it doesn't.
Averages hide a lot
Most of these measures are lopsided, with a few very large values. The median, the middle person, usually describes a typical man better than the mean, so you'll see both where it matters.
Who was studied
Much of the research comes from heterosexual adults in a handful of countries. Where that limits what the numbers can tell you, the page says so.
