How an erection occurs – 6 steps

It all begins when man receives a visual or physical stimulus that he finds exciting. In this situation, close to 10 seconds so that the man begins to experience an erection: his penis hardens and increases in size to prepare for intercourse. However, this response time can vary, it all depends on how powerful and direct the stimulus is.

But how does an erection occur? To explain it clearly, you must first know the penis anatomy.

In it fluffy tissue, located in the lower part of the phallus, are the arteries, veins, smooth muscles, spaces and fibrous tissues of the penis. While the cavernous bodies They are present along the penis, from the pubic bone to the glans, which is where the erectile tissue is found.

All these parts of the penis play a fundamental role in the erection.

When a man receives a stimulus that generates excitement, the muscles found in the corpora cavernosa relax, allowing blood to flow and fill the erectile tissue found in this area. Due to this flow of blood, significant pressure is generated in the corpora cavernosa, which makes the penis expand.

But for penetration to be effective, it is not enough for the penis to increase in size, it also needs to harden. This process is achieved when the tunica albuginea, the membrane that surrounds the corpora cavernosa, traps blood in the penis, without allowing it to flow to other parts, in this way it is achieved. the rigidity necessary for pleasurable penetration.

After ejaculation, or in the absence of continuous sexual stimulation, the corpora cavernosa empty of blood and the penis returns to its normal size at rest.

It is important to note that there is no relationship between the size of the penis at rest and what it will have during erection, as there are phalluses that can even reach double the size. This is due to the flexibility of the muscles involved, so it is difficult to predict the size that a penis acquires when erect.

Although erections are commonly due to a stimulus that is exciting for men both psychologically and physically, the penis can also increase in size without these conditions existing, for example when it occurs. the morning erectionor involuntary erection during growth phases.
