To be blunt, the mushroom part of the penis (the head) is called the glans. This is where most of the nerve endings are located and bundle. It’s also why this part of the penis is extremely sensitive. The highest level of nerve endings are laced around the outer ridge. Sensitivity is increased when the man is uncut. The shaft is also highly sensitive but has fewer nerve endings than does the head.
This is an area that responds well to longer periods of play without causing immediate eruption. For men who are super thick (see post on guys with thick dicks, keep this in mind. The distinctive “V” shape under the head of the penis is where the glans meets the shaft. It is somewhat sensitive but not as much as the head or shaft. Still, a good place to focus on with the tongue. The nutsack, also called the scrotum, serves as a protector and regulator for the testicles. It is one of the most sensitive parts on a guy's body. Touch it the right way and it can send waves of pleasure.
Incorrectly touch him in this area and it can cause pain. The scrotum responds well to light touching, licking, sucking and caressing.
