If you think that your penis is too small, be sure to measure it accurately. Even if it is shorter than average, it's important to place the size of your penis in context and ask yourself why it is causing you such distress. It sometimes helps to speak with a psychologist who can help you sort through your feelings and provide the perspective you need.
A fairly common way for surgeons to add volume in such areas of the body as the face and butt, fat grafting is also an option for the penis. Dr. Tim Neavin, a plastic surgeon in Beverly Hills, California, says that some surgeons have been doing penile fat transfer (also called composite augmentation phalloplasty) for decades. In this technique, a surgeon takes fat from the belly or inner thighs and injects it into the penis to increase girth.
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.
