The erogenous teather of the ridged band also called Taylor's band to the frenular delta and glans penis. Provides sexual pleasure when stretched by retracting the foreskin also serves to keep the foreskin forward protecting the glans penis and meatus.
When the penis becomes erect the traction on the frenulum provides extreme pleasure for the male.

The cord on the underside of a uncircumcised virgin guy's penis head. Destroyed in a haze of ectasy and pain the first time he has sex or during circumcision.
Luis moaned with pleasure as he lost his frenulum during his first ejaculation. Jake would never know the pleasure, having had his frenulum destroyed by circumcision.
