Contrary to popular belief, your penis is not a muscle, nor does it contain a bone. It's better to think of it as a kind of sponge, which, when flaccid, is soft and malleable, but can quickly become engorged when filled with blood. Two large cylindrical chambers, the corpus cavernosum and the corpus spongiosum (see?), fill with blood during arousal, causing your penis to harden and grow in size.
Dermal fat grafting (DFG) involves the extraction of a patch of skin from the patient's own body (usually the lower back, lower abdomen, or buttocks) along with a layer of fat. After the skin is removed from the penis, the extracted tissue is grafted in its place. Because the extracted skin is thicker, it will increase the circumference of the penis. By taking tissue from the patient's own body, the risk of rejection is low.
Dark chocolate is concerned as a nutrient food, because it not only helps you increase sexual life, but it also helps you rise up blood flow because it has flavonol. Many people like dark chocolate because it is the best type of chocolate, it is rich in cocoa, antioxidants, and has a little sugar. Dark chocolate also helps you detoxify your body, as well. Certainly, this kind of chocolate has a lot of calories to supply your energy.
Stretching with weights. Weights or stretching exercises won't bulk up your penis -- it's not a muscle. But hanging weights off your flaccid penis may stretch it a bit, O'Leary says. The catch is that it requires a freakish degree of dedication. "You might have to wear a weight strapped to your penis eight hours a day for six months," says O'Leary. At the end of it, you could be lucky enough to gain about half an inch. Risks include tearing of the tissue, burst blood vessels, and other problems.
