Foreskin
In older boys and adult males, the foreskin can be pulled back. In baby boys, the foreskin is usually attached to the glans of the penis and should not be forcibly pushed or pulled back for cleaning. In the United States, medical advice is usually that parents should gently pull back their son's foreskin part way back for cleaning after the baby is one year old. Soap should not be used -- just warm water. Pulling a baby's foreskin back too early (especially before six months of age) can damage it and cause scar tissue to form. When a parent is able to pull the foreskin back, it is important to do so gently and only pull it back as far as it will go. The parent should not make the baby cry or bleed. When the foreskin can be pulled back, the area under the foreskin needs to be cleaned every day. In Europe, where uncircumcised penises are much more common, parents are often told they do not need to pull back a boy's foreskin for washing.
