In contrast to common believe, the small penis syndrome is a mental disorder, subsumed under body dismorphic disorders (BDDs) and/or anxiety disorders. Basically, it’s a wrong perception of the own body, Men affected by it believe their penis is way too small, are almost obsessed by this thought, although their manhood has a normal length and girth. While the symtoms are very severe, including depression, anxiety and isolation, it’s a very rare psycological disorder. It’s often triggered by very negative personal experiences, e.g. rejection by a woman and other sexual problems. In case you think your penis is tiny, but has normal measurements, seeking professional help is recommended. There is also a very detailed article by clinical psychologist Ph.D. Mark Dombeck on MentalHelp we recommend for more details about SPS, characteristics and treatment. He points out: “It appears to us that some men have perfectly adequate penises, based on the measurements they’ve communicated. These penises are not going to break any world records, but they are probably just fine, however, these men are firmly convinced that they are hopelessly inadequately small.”
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.
