The frenulum is a Y shaped web of skin that connects the foreskin
to the underside of the head of the penis. The frenulum is kind of
like the web of skin under the tongue. This is the most sensitive
part of the penis, containing a huge number of nerve endings.
Circumcision usually removes all or most of the frenulum. For more
information see The Effects of Circumcision by Glenn M.J. Epps'
Circumcision Facts.
