Guys, how many of you know more about tail pipes on a car or motorcycle or the pipes in your house than your own plumbing? Ladies, how well do you know his little friend? For as often as we have sex or want to have better sex, isn’t it about time that you knew and understood the penis?
1. Think of Masturbation as a Healthy Workout
You need to have erections regularly to keep your penis in shape. To maintain a healthy tone, the smooth muscle of the penis must be periodically enriched with oxygen by the rush of blood that engorges the penis and makes it erect. Without regular erections, penile tissue can become less elastic and shrink, making the penis 1-2 centimeters shorter.
2. Smoking Can Stunt Your Growth
Smoking can shorten your penis by as much as a centimeter. Erections are all about good blood flow, and lighting up calcifies blood vessels, stifling erectile circulation.
3. A Penis Can Be a Grower or a Show-er
Among men, there is no consistent relationship between the size of the flaccid penis and its full erect length. In one study of 80 men, researchers found that increases from flaccid to erect lengths ranged widely, from less than a quarter-inch to 3.5 inches longer. On average, a limp penis will increase in volume 300% when it is erect. It will also contain more than eight to 10 times its normal amount of blood.
4. Sweet Dreams
Impulses from the brain cause on average 11 erections during the dreaming phase of sleep, known as the REM phase. It doesn’t matter if you’re having a hot sex dream or a zombie apocalypse nightmare — the penis just gets hard during that period of the sleep cycle.
5. Want to Appeal to a Man’s Most Sensitive Side? It’s Likely Not in His Head.
The head of his penis, that is. In a study published in the British Journal of Urology International in 2009, the underside of the glans and underside of the shaft had the highest sensitivity rating for a significant majority of men, followed by the upper side of the glans, left and right sides of the glans, sides of the penis, upper side of the shaft, and foreskin (for the minority of men who were uncircumcised).
6. Every Penis Was Once a Clitoris
Every penis in the womb starts as a clitoris before hormones ‘sex’ the brain of the to-be male. The penis retains the mark of its female heritage with the dark underskin and the thin ridge or seam, known as the raphe, which runs from scrotum to anus, which is a fusion of the vaginal lips.
7. Sensitivity Declines with Age
From age 25 on, sensitivity in the penis starts to decline. The sharpest decline in sensitivity is seen between ages of 65 and 75. However, it’s not known if most men are aware of it. They rarely report this condition to their doctors.
8. Vibrators Work on the Penis, Too
Vibrators aren’t just for women. They work on the penis, too. In fact, vibration is so effective on the penis that often men with spinal cord injuries can ejaculate with the aid of a special medical vibrator. For this kind of treatment, the vibrator is usually held against the underside of the head of the penis.
9. It’s Bigger Than You Think
Most guys would be proud to know that their penis is twice as long as they think it is. That’s because half the length of the penis is inside the body. Just like you don’t see all of a big oak tree above ground, you don’t see the root of a penis tucked up inside your pelvis and attached to your pubic bone.
10. Most Men Aren’t Circumcised
Worldwide, approximately 30% of males aged 15 and older are circumcised, according to a 2007 report from the World Health Organization (WHO) and UNAIDS. According to the report, rates vary greatly depending upon religion and nationality. Almost all Jewish and Muslim males in the world have circumcised penises, and together they account for almost 70% of all circumcised males globally. About 80% of American men are circumcised.
11. Sometimes Bigger Isn’t Always Better
An enlarged prostate gland can cause both erectile dysfunction and premature ejaculation.
12. Women Usually Win Out
Sorry, guys. The average male orgasm lasts six seconds. A woman’s typically lasts 23 seconds.
13. Suck My Dick?
Only one man in 400 is flexible enough to give himself a blow job. It’s a safe bet that all 400 have given it their best shot at some point.
14. Yes, a Penis Can Rupture
The most common cause of penile rupture is vigorous masturbation.
15. Once you go Black?
The Kinsey Report verified the longstanding rumor that black men have larger penises than white guys, but not by much. The average black male’s hard-on measures 6.3 inches, leaving the white man in a close second with a mean of 6.2 inches.
16. The Way to a Man’s Heart is Through His Nose
The smells of licorice, pumpkin pie, lavender, donuts and chocolate are reputed to increase penile blood flow. (Note that beer and bacon didn’t make the cut.)
17. Funky Spunk
Asparagus, red meat and dairy are reported to produce the least pleasant-tasting jizz. So much for Steak and Blow Job Day?
18. It Really Doesn’t Pay to be Big
The largest penis ever to be medically verified was 13.5 inches long and 6.25 inches in circumference. Just to put that in perspective, the average vagina is three to four inches deep.
19. Yet Size Does Matter
According to a study published in the Journal of Sexual Medicine in 2012, women who are more likely to have vaginal orgasms say it is easier to orgasm with men who have longer penises. Though it’s not clear exactly why, a longer penis may be better able to stimulate the vagina and the cervix.
20. Men will go limp if they drink too much
How much is too much? About 3½ drinks for a 150-pound man. Big guys, go ahead and drink up.
