The penis is part of the male genitalia.
· The part of the penis that is attached to the body is called the root.
·   The main part of the penis is called the shaft or body. This part is normally hairless.
·   The tip of the penis is called the glans or head. It is very sensitive. On the glans you see the meatus, through which urine and semen pass.
·   If a guy is not circumcised the glans is (sometimes partly) covered by the foreskin.
·  At the underside you can see the frenulum, which connects the glans with the foreskin. This is the most sensitive part.
·   Behind the penis we find the scrotum, which contains the testis.
