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.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there -- penis pills, creams, brutal stretching exercises, horrific-looking devices, and penis surgery. Almost none of it works. The few approaches that can work often have modest benefits and serious side effects. How serious? In some cases, erectile dysfunction-serious.
