There are certain benefits to being circumcised, such as the fact that the foreskin is long enough to cover the glans, which can play a role in protecting the glans from external friction and impact. The foreskin can keep the glans area moist, which prevents the glans skin from becoming too dry. In addition, circumcision can keep the glans in a more sensitive state, which is helpful for sexual life. But circumcision can also bring more disadvantages, such as circumcision is not easy to clean hygiene, more likely to occur inflammatory infection. In addition, the foreskin may cause the glans skin to be too sensitive and produce premature ejaculation.
