Some facts about penis.

These are some hidden facts about the penis but may not be related to how the penis works.

Penis Fact #1
Smoking can shorten your penis by as much as a
centimeter. Erections are all about good bloodflow,
and lighting up calcifies blood vessels, stifling erectile
circulation. So even if you don't care all that much
about your lungs or dying young, spare the li'l guy.
Penis Fact #2
Doctors can now grow skin for burn victims using the
foreskins of circumcised infants. One foreskin can
produce 23,000 square meters, which would be enough
to tarp Wembley more than three times with human
flesh.
Penis Fact #3
An enlarged prostate gland can cause both erectile
dysfunction and premature ejaculation. If you have an
unexplained case of either, head to your GP for a
check-up.
Penis Fact #4
The average male orgasm lasts 6 seconds. Women get
23 seconds. Which means if women were really
interested in equality, they'd make sure we have four
orgasms for every one of theirs.
Penis Fact #5
The oldest known species with a penis is a hard-
shelled sea creature called Colymbosathon ecplecticos.
That's Greek for "amazing swimmer with large penis."
Which officially supplants Buck Naked as the best
porn name, ever.
Penis Fact #6
Circumcised foreskins can be reconstructed. Movable
skin on the shaft of the penis is pulled toward the tip
and set in place with tape. Later, doctors apply plastic
rings, caps, and weights. Years can pass until
complete coverage is attained...Okay, we'll shut up
now.
Penis Fact #7
Only one man in 400 is flexible enough to give himself
oral pleasure. It's estimated, however, that all 400
have given it their best shot at some point.
Penis Fact #8
There are two types of penises. One kind expands and
lengthens when becoming erect (a grower). The other
appears big most of the time, but doesn't get much
bigger after achieving erection (a shower).
Penis Fact #9
An international Men's Health survey reports that 79
percent of men have growers, 21 percent have
showers.
Penis Fact #10
German researchers say the average intercourse lasts
2 minutes, 50 seconds, yet women perceive it as
lasting 5 minutes, 30 seconds. Are we that good or
that bad?
Penis Fact #11
Turns out size does matter: The longer your penis, the
better "semen displacement" you'll achieve when
having sex with a woman flush with competing sperm.
That's according to researchers at the State University
of New York, who used artificial phalluses (ahem) to
test the "scooping" mechanism of the penis's coronal
ridge. Next up: curing cancer.
Penis Fact #12
The penis that's been enjoyed by the most women
could be that of King Fatefehi of Tonga, who
supposedly deflowered 37,800 women between the
years 1770 and 1784 – that's about seven virgins a
day. It's good to be king.
Penis Fact #13
Better-looking men may have stronger sperm. Spanish
researchers showed women photos of guys who had
good, average, and lousy sperm – and told them to
pick the handsomest men. The women chose the best
sperm producers most often.
Penis Fact #14
No brain is necessary for ejaculation. That order
comes from the spinal cord. Finding a living vessel for
said ejaculation, however, takes hours of careful
thought and, often, considerable amounts of alcohol.
Penis Fact #15
The most common cause of penile rupture: vigorous
masturbation. Know your limits.
