Other people's foreskins are black. Why is mine not so dark? My foreskin is too long, and the erection of vulva and neck is only 12 cm. Do prepuce operation, will pubic neck grow?

1. Natural change of penis color caused by sexual frequency or sexual intercourse times. Generally, before the age of 30, the color of male penis is basically the same as their flesh color, and there is not much difference. However, after the age of 30, especially after the age of 35, the color of male penis will become darker as a whole, and the foreskin of our yellow penis, especially under the coronal sulcus, will gradually turn black, and these colors will also deepen with the increase of sexual life times. The reason here is that during sexual intercourse, melanin in the human body will precipitate on the penis, which will turn black over time. 2. It doesn't matter if the foreskin is too long, and it doesn't affect sexual life. Pay more attention to personal hygiene, that is, no surgery. Circumcision won't make your penis bigger.
