Missing frenulum

Missing frenulum The frenulum is a web of tissue connecting the foreskin to the underside of the glans (similar to the frenulum under the tongue or the upper lip). The penile frenulum is densely nerve-laden and is described as a male 'G-spot' — a very erogenous part of the penis. Circumcision often destroys the frenulum. Top Circumcised penis with no frenulum. Lower: Intact penis with retracted foreskin and an intact frenulum.
