and the 100 interesting facts about them

- The word “penis” is from the Latin meaning “tail.” The plural of penis is penises or penes. The word “phallus” is sometimes used to mean “penis,” but traditionally it is used to describe images or symbols of the penis.h
- Alternate words for “penis” include Adolph, anaconda, baby-maker, baloney pony, bell on a pole, cock, chopper, cum gun, deep V diver, dikk, ding-a-ling, disco stick, Excalibur, fukk pole, jimmy, joy stick, love muscle, meat stick, pink cigar, pork sword, prick, skin flute, spit stick, third leg, trouser snake, wang, wick, yard, yogurt gun, and many more.h
The largest penis in the world belongs to the blue whale
- The blue whale has the largest penis of any animal, typically measuring between 8 and 10 feet long with a girth from 12 to 14 inches. Its testes weigh between 100-150 pounds and can ejaculate over 35 pints.h
- Most mammals have a bone called the baculumor 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.g
- 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.a
- The human penis is larger than that of any other primate, both in terms of proportion to body size and in absolute terms.h
- Domestic cats have barbed penises. They have about 120 to 150 one-millimeter-long spines that point backwards. When the penis withdraws from the female cat, the spines rake along the vagina, triggering ovulation.h
- Male canines are the only animals that have a locking bulbus glandis at the base of the penis. When the penis is fully inside the female, the glandis becomes engorged with blood. When the female’s vagina contracts, the penis becomes locked inside the female, which is also known as “tying” or “knotting.”h
- Doctors can use the foreskins of circumcised infants to grow skin for burn victims. Just one foreskin can create 23,000 square meters of skin.a
- A hard-shelled sea creature named Colymbosathon ecplecticos is the oldest known species with a penis. Its name means “amazing swimmer with large penis” in Greek.a
- Only one man in 400 is flexible enough to give himself oral sex.h
There are two kinds of penises: a grower and a shower
- There are two kinds of penises: 1) a grower, which expands and lengthens when erect and 2) a shower, which looks big most of the time, but doesn’t get much bigger after an erection. Approximately 79% of men have growers and 21% have showers. In other words, a man whose has a small flaccid penis might have a surprising big erection. Conversely, a man with a big, limp penis might not get a significantly larger erection.f
- King Fatefehi of Tonga most likely has the penis with the most action. He supposedly deflowered 37,800 women from 1770-1784, or about 7 women a day.a
- There is a penis museum in Iceland.h
- The average erect penis size is between 5-6 inches. A flaccid penis is around 3.5 inches.b
- A bottle-nosed dolphin named Freddie was known to tow bathers through the water by hooking his large penis around them.p
- In a condition called Diphallus, males are born with two penises. Usually, only one penis is fully formed and semi-functional. This condition affects about 100 men worldwide.b
- A condition called “Koro” or “penis panic” is a type of mass hysteria in which men believe their penises are vanishing. It’s more common in Africa and the Far East.b
- Squirrel monkeys and male baboons will gesture with an erect penis as a threat to predators or as a sign of impending danger.h
- The adult male elephant has the largest penis of any land animal at 6 feet on average. It is S-shaped when fully erect.h
- Most marsupials have a bifurcated penis, which corresponds to the female’s two vaginas. Male echidnas have marsupials beat with their four-head penises.h
Smoking can decrease penis size
- Smoking can shorten the penis by up to a centimeter. Because smoking calcifies blood vessels, it can impede erectile circulation, which create erections.a
- Men who have been hanged often get a “death erection” also known as "angel lust."b
- 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.b
- Globally, approximately 30% of men over 15 years old have been circumcised, according to a 2007 WHO report. However, nearly all Jewish and Muslim males in the world are circumcised and make up 70% of all circumcised men in the world.f
- Approximately 80% of American men are circumcised.h
- 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.l
- Studies show that women who orgasm through vaginal stimulation were pickier about penis size than other women.l
- The smallest natural human penis ever recorded was 5/8 of an inch. The longest erect penis on record is 13 inches.k
- A man has an average of 11 erections per day. He has around 9 erections at night.q
- The signal to ejaculate does not come from a man’s brain—rather, it is sent from his spinal cord.q
- To maintain a healthy tone, the penis needs to have erections regularly. Without regular erections, penile tissue can become less elastic and shrink, up to 1-2 centimeters. However, the brain has an “automatic penis maintenance” function. Brain impulses cause erections during REM sleep. For some men who are physically unable to have an erection, due to nerve trauma or blood vessel damage, they can use a device like a vacuum pump that causes the penis to swell with blood.f
- Most men report that the underside of the glans (head) of the penis and the underside of the shaft is the most sensitive to sexual pleasure, followed by the upper side of the glans.f
- Vibrators are not just for vaginas—they work on penises too and can even help men with spinal cord injuries ejaculate. For this treatment, a medical vibrator is held against the underside of the head of the penis.f
- 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.f
- 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 lower risk of getting HIV and other diseases.f

you can put your arm in a condom. Shouldn't have taken this list to figure that out.
