The cause of an erection is not simply blood flow, but rather INCREASED blood flow. When a man gets aroused, the body increases blood flow to the penis which causes the erection.

Does sugar cause sexual weakness in men?

Yes and no.The No.Sugar is needed to maintain a healthy blood pressure. If your sugar is too low, then your blood pressure will be too low. Since the male penis relies on blood pressure to form an erection, low blood sugar is a problem here.The Yes.Too much sugar can cause reduced production of testosterone and therefore reduced sexual drive. It can also cause diabetes, which can further cause loss of drive.The advice is to eat a healthy, balanced diet. Just eat as much sugar as you need (ie natural sugars from fruits) to maintain a healthy blood pressure and avoid too much sugary junk food to prevent loss of drive.


Is using a vacuum to increase penis size dangerous?

Vacuum pumping to increase the size of the penis has been around for over a hundred years. Various gadgets and gizmos have been invented to apply negative pressure to the exterior of the penis, usually in a tube, to cause increase blood flow and congestion in the penis. Vacuum pumping is a valid, recognized therapy to increase the firmness of an erection in men who have diagnosed erectile dysfunction caused by damage or disease processes like diabetes and atherosclerosis. These diseases impair the blood flow to the spongy tissues of the penis that cause an erection when filled with blood. The vacuum pump is used to engorge the penis until it is erect, and then a silicone or rubber constricting ring is fitted around the base of the penis to restrict the outflow of blood. This maintains the erection until sexual activity has concluded, and must be removed shortly thereafter. Some men use pumping as a "fetish" activity, and strive to create massively large erections. There are some magazines devoted to practitioners of pumping and they offer various tips to maximize the experience. There are many dangers associated with pumping, mostly related to physical injury. Repeated or excessive pumping can result in ruptured blood vessels, and damage to the corpus cavernosa (the spongy erectile tissue of the penis). Injuries such as this threaten the circulation in the tissues, can result in necrosis and may require amputation. In short, pumping can be fun, but like anything, is definitely dangers when taken to extremes.

Why do some men get painful erections with UTI's?

During erection, the urethra stretches and lengthens. A urethra that is already inflamed by a urinary tract infection (UTI) may become painful during erection and sexual intercourse. UTI's, in and of themselves, rarely cause erections. Unintended erections may occur as a result of hypersensitivity of the penis secondary to inflammation. Because of the capacity of UTI's to produce scarring and other deleterious effects, they should not go untreated. Don't suffer in silence or be embarrassed, seek medical help as soon as possible.

Why does my penis stick up?

You are experiencing erections which occur when you are sexually aroused. This normal. Many erections seem to happen for no particular reason.All of this is medical talk: "Physical and/or mental stimulation cause nerves in the brain to send chemical messages to nerves in the penis telling the penile blood vessels to relax so that blood can flow freely into the penis. Once in the penis, high pressure traps the blood. This causes the penis to expand and sustain an erection."The average length when erect is about 5.6" erect. If you are smaller, it will grow as you grow. Most males do rub or stimulate the penis. This is also normal.
