Before trying to understand anything about male enhancement orhow to get rock hard erections, it is important for you to known the real mechanics of your male sexual system or how an erection occurs.

In order to get an erection, several parts of the body must work together. The brain sends a message of sexual arousal through the nervous system to the penis. This message causes the muscles along the penis to relax.  At the same time, the artery to the penis dilates to twice its diameter, increasing the blood flow sixteen-fold, and the veins which carry blood away from the penis are blocked.

As a result, the two spongy-tissue chambers in the shaft of the penis fill with blood and the penis becomes firm.  

The penis contains two chambers, called the corpora cavernosa, which run the length of the organ. A spongy tissue fills the chambers. The corpora cavernosa are surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa.

Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand. The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining erection. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and opening outflow channels.

Erection, in the sexual sense, is the hardening, enlarging and rising of the penis which often occurs in the sexually aroused male. Erection enables sexual intercourse and some other sexual activities, though it is not essential for all of them. In addition to sexual arousal, erection can be caused by friction, retraction of the foreskin, or by the pressure of the filled urinary bladder. In healthy males, erections occur several times per night during the REM phases of sleep, and morning erections when waking up are common. These are called an "unprovoked erection". It is normal for them to occur 2 to 3 times a week. This is a good sign the erection pathways are functioning well. Erections already occur in infant boys, and in utero.

Physiologically, an erection is achieved by two mechanisms that play together: increased inflow of blood into the vessels of erectile tissue, and decreased outflow. The vessel system involved is known as the corpora cavernosa and the corpus spongiosum. After a signal from the sympathetic nervous system, muscles in the region relax, allowing more blood to enter the sponge-like tissues. Contraction of other muscles reduce the outflow. The enlarged structure then exerts pressures on the exit vein, further reducing the outflow.
