Penis – simple english wikipedia, the free encyclopedia electricity 220v


The length and thickness of the penis is different for different people. The size of a soft penis (not erect) is much smaller than when it is erect. Some penises grow more when they get hard than other penises. In most cases, whether a penis is big or small, it can still be used for sex. It averages out to be around 3 to 6 inches long when not erect. The average size of an erect human penis is between 13 – 16 cm (5.1– 6 in). [1] [2] [3] The average circumference of a penis is 12.3 cm (4.85 in) when fully erect. The penis grows bigger during puberty. At the start of puberty, the average length of the penis is 6 centimetres (2.4 in). The penis reaches adult size about 5 years later. [4] A study done in 1996 found the mean length of an adult man’s penis is 89 millimetres (3.5 in) when it is not erect. [1] The average length of an erect penis is about 12.9 to 15 centimetres (5.1 to 5.9 in). [1] [5] Circumcision [ change | change source ]

The foreskin is a fold of skin that covers the end of the penis. Cutting off the foreskin is called circumcision. The foreskin is connected to the head of the penis. During circumcision, the foreskin is removed from the penis. Circumcision is usually performed on infant males for medical, religious or cultural reasons. Circumcision is common in some parts of the world, such as the United States and the Middle East, but not common in some other parts of the world, such as Europe and China.

In some religions, babies and young boys have their foreskin cut off. This is expected in Islam and Judaism. [6] [7] It is not required according to Christianity. In Judaism, infant males are required to have their foreskin removed as a sign of the covenant (ancient promise) made with God. Skin color [ change | change source ]

A young boy’s penis skin is the same color as his other skin. At age 11 or 12, a boy’s penis skin gets slightly darker. This is normal because of puberty. This is caused by sex hormones (natural chemicals), especially testosterone. Testosterone makes more melanin. Melanin is the amino acid that causes skin color. (Sunlight also makes more melanin so skin gets a sun tan.) Usually a teenager or man’s penis side skin is slightly darker than other skin on his body. [8] [9] The tip (glans) of the penis is usually pink or red color even if the penis side skin is dark. If the man is not circumcised, the tip is usually covered by the foreskin. The foreskin is about the same color as the skin on the side of the penis.

If a man’s penis skin changes color and he doesn’t know why, he should go to a doctor. He could have an infection, diabetes or cancer. [10] A sunburn on the penis can happen quickly. If a man is outside without clothes, he will get a sun tan. That is normal. Too much sun causes a sunburn. Doctors say to use sunscreen (sun cream) before and after nude swimming. A sunburn can happen in a few minutes on a very sunny day. Related pages [ change | change source ]
