Even those penile extenders and stretchers that claim to work over time would actually just be stretching your flaccid length, and that has absolutely no correlation to how big you get when hard, says Fisch. So don’t waste your money on a product or service that swears it can give you five more inches. “There’s no actual scientific study that they rely on."
Another option for an “emergency” short term size increase is simply having a warm bath, a shower, wrapping your penis with a wet and warm towel or simply pulling it by hand. The blood flow increases and the flaccid size increases, too. The effect only lasts for minutes, but there are situations this may become handy, especially if you were in a cold environment before and your penis size has “shrunk” to even smaller than usual.
Some men are born with what’s called a micropenis, defined by the American Urological Association as a stretched penile length of 7.5 centimeters or less. Micropenis is a condition with varying degrees of severity and may include a hormonal imbalance. Having a micropenis does not necessarily make you a good candidate for any or all penis enlargement surgeries.
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.
Do a little Jelquing, or try Male Extra (more information available HERE) in order to get extra blood flowing to your organ. This is optional, but will help speed up the process. The key to most muscle and tissue recovery/growth is making sure the cells are getting oxygenated and receive the proper nutrients. Blood carries all of that to the tissue, so the more, the better.
“The penis extends for two to three inches inside the body in the pubococcygeus (PC) muscle, which can be strengthened in order to achieve stronger erections and orgasms. It also helps a great deal with obtaining better ejaculatory control,” says Hall. “The PC muscle, which surrounds the prostate gland, is like a valve around the genitals. Orgasm builds from the prostate, so learning to develop these muscles is highly beneficial. Doing PC muscle exercises helps to strengthen the muscle, and men can even add weight to help build it up,” says Hall.
Still, since size is so important to men, here are some elongation exercises that can help you make the most of your penis. Keep in mind that width is generally more satisfying than length, but if length is what you're after, here's how to get it naturally. More importantly, these exercises will not only increase the length and girth of your penis, they're good for you.
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.
