The foreskin is a layer of skin outside the glans penis. You can flip it. Can wrap the glans penis. You can also quit.

The foreskin can protect and moisten the glans penis, so as to keep its sensitivity.

At the same time, the foreskin is rich in sensitive nerves, which is an important sexual pleasure area.

It plays the role of lubrication, and the foreskin can cushion the contact between JJ and YD. Extend sexual life time.

This is why men have never been circumcised since ancient times. Many people are foreskin. Regard the foreskin as a treasure. It is only in recent years that advertisements in private hospitals have driven the circumcision fever.

people have been like this for thousands of years. Only in recent years, driven by the interests of private hospitals. Make a big advertisement and set off circumcision! Many people regret it!

just wash it often and turn it over. It will relax after a long time.

there is also the so-called "skinning dirt", which is actually a misleading misunderstanding! ! Even if you wash it clean every night, the next day still appears. What appears every day is foreskin secretion, among which lysozyme, which is recognized by the medical profession, is relatively clear. Is to play a role in killing germs.

but it's good to wash often. Lysozyme will work if you can't wash it often. It will kill bacteria.

That's why people in remote areas don't take a bath all the year round, and that's why people haven't got sick for thousands of years.

my answer is out of tune with the propaganda in those advertisements.

that's an advertisement driven by the interests of private hospitals! !
