The foreskin refers to whether the glans can't leak out or be wrapped inside when the penis is erect. It depends. If the glans penis leaks out manually, cleaning the dirty things inside is simple and convenient, and it will not affect your health. You can choose not to do it yourself, but it is recommended to do circumcision, because it will affect your sexual ability. The glans penis has been wrapped in it for a long time, so it is very tender. It will be very sensitive, so it will be over soon. The foreskin operation is to cut off the extra part of your foreskin, so that the glans penis can leak about half when you have no erection. This can not only ensure the health of the glans penis, but also improve its anti-sensitivity level-I am exhausted and hope to help the landlord.
