  4. Most mammals have a bone called the baculum or os penis in the penis, but it is absent in humans and horses. Although there are no bones in a human penis, a man can still suffer from penile fracture, which is when the thick membrane surrounding the erectile tissue tears. There is usually a “cracking” sound, an immediate loss of erection, and a great deal of pain. In extreme cases, the urethra can be damaged, which affects the ability to urinate.

  5. Though an adult chimpanzee is significantly smaller than an adult gorilla, it has a penis about double that of the gorilla. An adult gorilla’s penis is about 1.5 inches (4 cm) in length.

  7. The human penis is larger than that of any other primate, both in terms of proportion to body size and in absolute terms.

  8. Domestic cats have barbed penises. They have about 120 to 150 one-millimetre-long spines that point backwards. When the penis withdraws from the female cat, the spines rake along the vagina, triggering ovulation.

  9. Male canines are the only animals that have a locking bulbus glands at the base of the penis. When the penis is fully inside the female, the glands become engorged with blood. When the female’s vagina contracts, the penis becomes locked inside the female, which is also known as “tying” or “knotting.”

Approximately 79% of men have growers and 21% have showers. In other words, a man who has a small flaccid penis might have a surprisingly big erection. Conversely, a man with a big, limp penis might not get a significantly larger erection.

  16. The average erect penis size is between 5-6 inches. A flaccid penis is around 3.5 inches.

  23. Men who have been hanged often get a “death erection” also known as "angel lust."

  24. A man will ejaculate on average of 7,200 times during his lifetime. The average number of times he will ejaculate from masturbation is 2,000. The average speed of ejaculation is 28 miles per hour.

  25. Globally, approximately 30% of men over 15 years old have been circumcised, according to the 2007 WHO report. However, nearly all Jewish and Muslim males in the world are circumcised and makeup 70% of all circumcised men in the world.

  26. Women prefer big penises, but not too big. In fact, the returns of a bigger penis start to decline after a flaccid length of 2.99 inches (7.6 cm). However, larger penises were only more attractive on taller men with narrow hips and broad shoulders (V-shaped)–and not for shorter men. In other words, if a man is short and pear-shaped, a large penis will not increase his attractiveness.

  33. The penis is actually almost twice as long as men think they are. This is because half of the penis is inside the body. The root of the penis is inside the pelvis and attached to the pubic bone. In fact, an erect penis is shaped like a boomerang.

  34. There are at least 42 kinds of bacteria living on the skin of the penis. However, circumcised penises have fewer bacteria. In fact, circumcision has been linked to a lower risk of getting HIV and other diseases.

  35. A fish with a large penis on its head was recently discovered in Vietnam. The penis has a rod and jagged hook used for grabbing the female during sex. Although its scientific name is Phallostethus cuulong, its nickname is “penis head.”

  43. A “cock ring” is a constriction device that is placed around the penis alone, around both the penis and scrotum or around the scrotum alone (“testicle cuff”). Its aim is to restrict the flow of blood from the penis or scrotum to make an erection last longer. They are also called “tension rings” and “erection rings.” They can help men who battle performance anxiety and erectile dysfunction. Metal rings are typically considered safer than elastic rings.
