Why does the penis turn black?

The color of a man's penis is pink when he has not had sex, but if he has sex frequently, the color will change. The color of most men's penis will turn black. However, men who don't know much about sex are more worried about this situation, fearing that it is caused by their own physical illness. So, why does a man's penis turn black?

If you masturbate for a long time or have a lot of sexual experience, the penis will become very dark due to frequent friction and melanin deposition, which makes the penis more resistant to friction and more durable. The darkening and erection of the penis are signs of a man's mature penis. So your blackness is a sign of health. A white penis gives people a feeling of powerlessness and is not durable, which is not a good thing.

First of all, if you have not had any unclean sexual behavior recently and do not feel obviously uncomfortable, it means you are not infected with any sexually transmitted diseases.

Secondly, the color of the glans is dark red, especially the edge of the glans, because it has abundant nerve endings, abundant blood supply, and frequent friction. Therefore, when erect, the edge of the glans becomes darker, which is a very normal phenomenon. If the root of the glans is purple as you described, that is, the edge of the glans becomes darker red with a little purple-red, there should be no problem.

Finally, there are some dangerous situations when the glans penis turns purple. Generally speaking, the glans penis will not turn purple, but for some men with phimosis, when forced to have sexual intercourse, due to the narrow foreskin opening, it will retract and get stuck in the coronal sulcus of the glans penis, which will block blood circulation and form penile incarceration. If the blood is blocked for a long time, the penis will turn purple and die, which is the most serious situation. But from your situation, it should not be this problem, so don't worry.

The blackening of the male glans may be caused by long-term erection and congestion. In this case, male friends need to arrange their sex life reasonably and have sexual intercourse in moderation to avoid causing other male diseases. In addition, there are other disease factors, such as balanitis, which may also cause the blackening of the male glans, mainly due to bacterial infection of the glans and long-term inflammatory stimulation. In the third case, the blackening of the male glans may also be caused by medication, which causes the glans to turn black due to long-term stimulation of the drug.

Considering your own situation, you may decide whether you are healthy or need medical attention.
