fun penis facts

here are some fun facts from a "sexual records" site, compiled primarily from institute for sex research data

Average Penis Size
Almost 88% of all men fall between 5-7 inches when erect, and when relaxed the majority (again, 90 fall within 3 to 5 inches

Flaccid penis length (in.)

Erect penis length (in.)

Flaccid penis circumference (in.)

Erect penis circumference (in.)

Average Erection Angle
15 degrees above horizontal.

Average Time to Achieve Erection
3-8 seconds.

Average Ejaculatory Speed
28 miles per hour (45 km/hr). Once it enters the vagina, the sperm takes 5 minutes to cross the 6 inches of territory to the cervix (.0011 mph), namely because they no longer have flight accommodations and must hoof it on foot, so to speak.

Average Ejaculatory Volume
4 cc. or about one teaspoon, with enormous variation between individuals and times.

Average Ejaculate Calorific Content
Between 2 to 5 calories or so.

4 microns.

Average Sperm Concentration
20 million sperm per milliliter.

Average Seminal Alkalinity
7.0 to 8.0 on the pH scale.

Average Seminal Viscosity
0.00935 Pa. s (water, by comparison, has a viscosity of 0.001 Pa. s)

Average Durability of Sperm
Sperm typically survive 48 hours within the female body.

Average Number of Sperm
300-500 million sperm are released every ejaculation, and 1.2 trillion sperm are produced during a man's lifetime.

Average Time to Orgasm (male)
Kinsey found that 75% of all males reach orgasm within 2 minutes of penetration, and felt that it was normal, though he does note that it "may be most unsatisfactory to a wife who is inhibited or natively low in response."

Average Duration of Orgasm (male)
3-5 seconds.

Thanx for the interesting facts

Always good to get the data but then again I'm a ex chemist turned engineer!

PS. How do they measure the penis length anyway? There's a big difference between measuring topside to tummy or bottomside to balls... Any idea?
