Performed on the halfway tumescent penis, jelqing is a manual manipulation of simultaneous squeezing and stroking the shaft from base to corona. Also called "milking", the technique has ancient Arab origins. Despite many anecdotal reports of success, medical evidence is absent. Journalists have dismissed the method as biologically implausible, or even impossible, albeit unlikely to seriously damage the penis. Still, if done excessively or harshly, jelqing could conceivably cause ruptures, scarring, disfigurement, and desensitization.
It's ironic that the male preoccupation with enhancement seems to be independent of the needs of women, the supposed benefactors of improved sexual performance. A recent study found that 85% of women are pleased with their partner's penis proportions, but 45% of men say they want a larger penis. Given that the vast majority of men fall within a certain penis size -- about 5.5 to 6.2 inches long when erect -- most men fall within the normal range.
Many manufacturers market the products as dietary supplements because the products contain natural ingredients, including vitamins and minerals. When shopping for male enhancement products, read the label carefully. You might find that the product contains the same ingredients as those found in a multivitamin. You should also look at what the product does because not all supplements promise the same thing. Some shoppers want a male enhancement supplement that increases stamina, but some men want a product that only contains natural ingredients.
