A penile insert device effective to prevent retraction of the penis and to increase the length of a penis in its flaccid or erect state. An elongated body of the penile Insert device can have a proximal end, a distal end, a first side edge, a second side edge, a top surface, and a bottom surface. Each of the first and second side edges has a plurality of lateral valleys notched therein. The lateral valleys of the first side edge are staggered with respect to the lateral valleys of the second side edge so as to form a zigzag pattern in the body. The device can be implanted into a penile shaft and attached to a penile facial tissue layer via sutures that are retained in a suture system of the device.
