Every guy has one, so when the word goes, it's as familiar as the back of the hand - right? Actually, as much as the penis is an important section of every man's life, not everything about any of it is obvious, & most men can learn something or two about its anatomy, its inner workings, and how exactly to keep carefully the penis healthy and ready to use it. Guys who think they know everything there is to know about the manhood can put their knowledge to the test here:1. The penis is actually about doubly long as it looks- very good news for guys who are concerned about their penis size. The external shaft isn't the whole story; the rest of the penis is rooted deep in the pelvis, supported by connective tissue, giving it the thrusting power needed to penetrate a partner.2. The foreskin is not just an extra little bit of flesh - in fact, the foreskin has a number of important functions aside from just within the glans once the penis is flaccid. In infants, this fold of skin, which is also called the prepuce, serves to safeguard the delicate tissue underneath from urine and fecal matter. The prepuce can be filled up with neural tissue and contributes to the sensitivity of the penis, and also acting as an all natural lubricant during intercourse.3. The smallest penis size ever measured in a human was 5/8 of an inch. However, the biggest penis on record was 13.5 inches long. Fortunately for women, most men fall somewhere within the 4.5 to 5.5 inch range - plenty of to come in contact with all of the inside of a vagina.4. Talking about penis size, the simplest way to increase it is... to lose weight. It's true - since penis function is not dependent on what size it really is (see item 3 above), concerns about penis size are actually all about perception. Therefore, the most efficient - and realistic - solution to address the size issue is to make it look bigger. Easy enough - losing even an inch or two off the waistline can make the penis appear more prominent. As an added measure, shaving and keeping the region well-groomed can allow more of the majesty to shine through.5. The average number of erections per day- 11 (during the waking hours). Add another 9 for nighttime wood. However, once an erection is... spent... normally it takes anywhere from 2 minutes to 14 days to obtain it back. This recovery time is called the refractory period.6. The penis could be a fashion statement- Tribal men in northern Uganda weigh their penises to make them longer. Occasionally, they are so successful that they have to knot them up to keep them from dragging. In the brand new Hebrides, men wrap their penises in yards of cloth - making them appear up to 17 inches long. Royal fashion in Europe in the 14th century also made allowances for the penis - men who were handsomely endowed were permitted to display their packages, allowing them to hang from underneath a short tunic.Care and feeding of the penisWhatever the condition of the penis in terms of its size, girth, or status as a fashion accessory, it requires to be nourished, just like the rest of the body. Keeping the penis smooth, supple, attractive and attentive to sexual stimuli requires proper nutrition. Applying a penis vitamin cr�me (health professionals recommend Man1 Man Oil) containing nutrients such as vitamin C (to support the blood vessels and connective tissue), vitamin A (to keep the skin's youthful, supple texture), proteins (for nerve tissue health); and natural moisturizers such as for example shea butter may help to lessen signs of premature aging, prevent irritation and dryness, and improve the general health and appearance of the penis.For additional information of all common penis health issues, tips on improving penis sensitivity, and what to do to maintain a wholesome penis, visit: [1].
