Little secrets about "little brother" that most men don't know

The penis, as a man's reproductive organ, is also an important tool during sex, so we should know more about it. But in fact, there are some little secrets about the penis that even men themselves don’t know. Most men only regard their penis as a spongy body and a sexual tool. Although we usually take good care of it, we know very little about it. To this end, the editor lists 7 secrets of the penis, let’s learn about them together.

1. Use it or lose it

The so-called use it or lose it means that if the penis is not erected frequently, the elasticity of the penis tissue will weaken, causing the penis to shorten by 1 to 2 centimeters. Like any other part of your body, your penis needs regular exercise. The smooth muscle of the penis needs to be maintained by oxygen regularly during engorgement (erection). During sleep, stimulation from the brain can cause an erection. Damage to the relevant nerves or damage to the nerves or blood vessels caused by diabetes can cause erectile difficulties.

2. The difference between "explicit" and "implicit"

The penis can also be divided into visible and invisible. A penis that does not increase significantly in length after erection is called a "dominant penis," and a penis that increases significantly in length after erection is called a "latent penis." Sexologist Alfred Kinsey measured the penis size of thousands of men and found that men with shorter penises could double their length after erection compared to men with longer penises in the non-erect state.

3. The most sensitive part is under the penis

Don't think that the penis is the most sensitive part. In fact, the most sensitive part is the bottom of the penis. The lower end of the glans and the underside of the penis are most sensitive to sexual pleasure, followed by the upper end of the glans, the sides of the penis, the top of the penis and the foreskin.

4. Sexual sensitivity

Several studies have shown that penile sensitivity decreases with age. The study found that the greatest decrease in penile sensitivity occurs between the ages of 65 and 75.

5. Oscillator

When we think of vibrators, we usually think of them as women. But vibrators are not just for female masturbation, they are also suitable for male penis stimulation. A study found that men with spinal cord injuries were able to ejaculate successfully with the help of a special medical vibrator. In this treatment, a vibrator usually stimulates the nerves under the penis that are involved in ejaculation. Dr. Kohler says some men who have trouble ejaculating or reaching orgasm can try a vibrator.

6. The penis is very likely to harbor bacteria

The health of private parts is something we pay more attention to. But we also need to know that the penis skin and foreskin can easily harbor a variety of bacteria. Researchers at the Phoenix Genomics Institute in Arizona, USA, discovered 42 unique bacterial species in the foreskin of the penis. After circumcision, the bacterial flora carried by the penis is significantly reduced. A study conducted in Uganda found that circumcision can reduce the incidence of HIV infection by 60%. Therefore, for the sake of their own and their wives' health, men should clean their private parts regularly.

7. Most men are not circumcised

We often hear about circumcision, but not many people undergo this surgery. Worldwide, only about 30% of males aged 15 and over are circumcised. This ratio varies by religion and country.

Do you have a new understanding of the penis? Of course, there is more to learn about the penis. We need to understand a little bit more so that we can better protect its health.
