Exercise regularly. Moving your body enhances circulatory healthy, strengthening the arteries that carry blood to your penis. If you don't exercise at all, your penis may not be realizing its full potential. Aim to exercise for about an hour a day, whether you want to go for a swim, a walk, a jog or a bike ride. Any type of exercise will help increase blood flow to your penis.
Penis pumps and vacuums are popularly used as sexual aids to promote erections in men. They are also used by some with the intent of increasing penis size. These devices are placed over the penis (and sometimes the scrotum) and use suction to engorge the penis with blood. If used consistently over a long period of time, they can cause the skin of the penis to become "spongy" and have a thicker appearance.
Not all agree though. Male enhancement pills and supplements seem sometimes to satisfy men who are looking for something that will not be permanent but are worried more about performance. “Penis pills don’t require a device or consistency and practice. I’ve seen pills work at making the penis not only harder, but also last longer. I always say that men have never seen the full potential of their penis. Until you pop some penis pills or try a cock ring or a penis pump, you will have never seen what your penis is capable of,” says Leo Debois of AdamsToyBox, a male-focused adult toy store.
