Three secrets men don't know about their "little brother"

For men, the penis is both the most familiar and the most unfamiliar organ. According to a March 5th report on the American website "WebMD," the following three points are "facts" unknown to many men:
1. It has its own will.
Many men have noticed that their penis can "take matters into its own hands," suddenly becoming erect when they don't want it to. Research has found that compared to other parts of the body, such as the limbs, a person has limited control over the penis because it is not always under the control of the nervous system, but is also led by the "autonomic nervous system," also known as the vegetative nervous system, which is also responsible for regulating heart rate and blood pressure. Many sexual arousals are thanks to the autonomic nervous system. For example, during the REM sleep stage, impulses from the brain can induce an erection, and weightlifting and abdominal contractions can also promote penile erection. 2.
The penis can also shrink unexpectedly. Dr. Montag, an American urologist, points out that exposure to cold water or air can cause the penis to shrink, and psychological stress can also make it limp. These are all controlled by the autonomic nervous system, therefore the penis can also be considered a "barometer of the autonomic nervous system."
2. It's "low-key":
The size of the penis varies from its normal state to full erection. A study of 80 men found that the change ranged from 0.6 cm to 8.9 cm. Sexologist Kinsey, after studying more than 1,000 men, also found that 12% of men saw their penises increase by less than one-third after erection, and 7% saw them double. Those penises that appear short in their normal state may be twice the size of those "larger" penises after erection.
3. It can break:
Although there are no bones inside the penis, it can still break, making a sound, then turning blue and extremely painful. This mainly happens to young men. A typical case is when a man is too hasty and accidentally hits his partner's pubic bone. To avoid this, avoid being too rough during sex. If the woman is on top, her movements should not be too vigorous.
