A short frenulum can rip during sexual activity with painful and very bloody consequences. The bulbous head of the penis . The primary area of sexual sensitivity to touch. In the uncircumcised the glans is generally covered by foreskin when the penis is flaccid although the amount of this covering varies between men from 'complete with overhang' to 'none at all'. During erection the foreskin should slide back to uncover the glans to allow it to be fully stimulated but often the foreskin is too tight or long and fails to fully retract.
Circumcision permanently bares the glans allowing full stimulation during sex.
Haemophiliac A male whose blood does not clot properly due to a genetic defect. Conventional surgery on a haemophiliac can result in considerable loss of blood and is thus to be avoided as far as possible. When used to describe the position of the circumcision scar line, this is taken to mean closer to the base of the penis and further from the glans. Hypospadias A condition in which the urethra opens onto the under side of the shaft of the penis instead of at the tip of the glans. A boy with hypospadias should not be circumcised until after the hypospadias has been assessed by a urologist and any corrective action taken.
