Let’s face it. Penises are pretty cool. They provide pleasure while perpetuating the human race. Freud noted that human genitalia is, objectively, not exactly beautiful but that we lust after it anyway, at least when it’s attached to the right person. Here are 9 fascinating facts you probably didn’t know about penises.
#1. The average erect penis is about 5.56 inches
The average erect penis is about 5.56 inches (14 cm) long, according to a 2013 study detailed in the Journal of Sexual Medicine that surveyed 1,661 men. But variety is the spice of life, and men in that study had members that ranged from 1.6 inches (4cm) long to 10.2 inches (26 cm) long. Not all erections were created equal. Those who measured their penises after oral sex or intercourse sported larger penises than those who relied on fantasy alone, the study found. And because it reduces blood flow to the penis, smoking can shorten the average penis by up to 0.4 inches (1 cm), other studies have found. Source
