Frenular delta

The frenular delta in human anatomy is the triangular area underneath the penile glans along the penile ventral body, and is composed of a mucosa. The frenulum attaches at the top of the triangle and outlines its sides, which connect with the ridged bands. The delta is highly innervated, and is considered a specific erogenous zone. The frenular delta is sometimes removed during male circumcision.
