Most importantly, exercise. The most optimal and beneficial to all scientific data is dosed physical exercise (daily walking in the fresh air for 40-60 minutes). As for smoking - it is an aggressive factor in erectile function. Scientific data indicate that after one cigarette fumigate blood flow in the penis is reduced by 30 percent within 3 hours. If you smoke a day for 8 cigarettes, consider that during the days of your penis is working in the mode minus 30%. Of course, until the young organism, it is not clinically manifested. But over time, if you continue to smoke, be sure your penis will remind you about it. Still, in order to always stay strong, you must exclude themselves from such cardiovascular risk factors as smoking, obesity, stress factors, eat rationally (to exclude animal fats, beer, weak alcohol, etc.) for physical loads and regularly engage in sexual activity.
