Originally from Is the penis a muscle? - Penis Enlargement Gym That article attempts to oversimplify the penis while being erroneous at the same time. "The penis is not a muscle so you can't enlarge it"- this statement has been repeated so often that a lot of people believe it without a second thought. It exposes the ignorance of the author on matters of penile anatomy. The penis is composed of fascia (like the kind that covers muscles), smooth muscle tissue, blood vessels, nerves and ligaments (also like the kind attached to muscles). Its function requires that it be capable of expanding to many times its original size. Knowing this, expanding it a little beyond its normal erectile maximum each time using PE exercises shouldn't be that difficult a concept to accept. Here are some articles that explain penile anatomy. Feel free to post them in the Yahoo Answers page you visited: Penis Enlargement Gym - Penis Anatomy 101 Penis Enlargement Gym - The Penis is a Muscle! To answer your questions: Q. If you stretch it will it get more pencil like and lose it's thickness? A. That shouldn't happen. Since you'll be stretching out the penile tunica (which is responsible for containing the penis itself), you'll actually realize some girth gains while stretching. Note that there are girth specific exercises that you can do as well. The only instance where you'll probably see a decrease in girth from stretching is in cases where the penile function is destroyed (and blood flow inhibited), like what happens to some tribes that hang extremely heavy weights and do all sorts of torturous things to their penises. Q. Will the elongated penis be harder to get erections with because it is longer than what you should have? A. Not necessarily, although a larger penis is going to require more bloodflow. That's why it's highly recommended that you do stamina work like kegels, etc. along with your PE exercises. Q. Can these exercises cause serious damage? (My guess is no because it's just pushing blood through your shaft) A. You can injure yourself if you perform PE exercises incorrectly. The same case can be made for almost any exercise- PE or not. If you go into PE using moderation and patience, you should be injury free.
