The average health education class, in which men are introduced to male organ anatomy for the very first time, typically takes place during an awkward time in a boy's life. Often, he's much too young to have experienced the benefits of a healthy male organ, and even talking about intimate tissues might make him giggle, blush or just shut down altogether. As a result, it's not uncommon for men to know very little about how their bodies work and what might be done to keep their most intimate parts functioning at peak capacity. This information can fill in the blanks for guys who tuned out during health class, as it outlines major structures and male organ care techniques that can keep things running smoothly.
1. All about the Flow. The male organ is often described as a tube, and in many ways, that's an accurate description. After all, the male organ is designed to transmit all sorts of fluids outside of a man's body in a quick and efficient way. However, the male organ is also lined with hollow spaces known as the corpus cavernosum and corpus spongiosum. These spaces are vital to a healthy response, as they can accept the blood that streams to the area during tumescence. When they're filled with blood, the area stiffens and rises from the body. When they're empty, the male organ is flaccid.

2. Vital Chemicals. Blood doesn't enter the pelvic area through mere suggestion and willpower. Instead, it's summoned there by an intricate network of nerve cells, linking with chemicals released by the brain. When a man senses a sensual signal, his brain releases the neurotransmitter noradrenaline. This chemical triggers a series of further chemical reactions in the male organ, relaxing muscles and opening blood vessels so that blood can flow into areas that are normally closed off and empty. These reactions are completely involuntary, meaning that there's no higher thought involved, and they can work within the blink of an eye. As soon as a man senses intimacy is coming, the process is set in motion and his body gets prepared.
3. A Delicate Wrapper. All of this blood flow is encased in a wrapper of intensely sensitive skin. This skin isn't remarkably different than the skin that encases the rest of a man's body, but it's typically hairless and is normally protected within a man's clothing for the vast majority of the day. As a result, the skin is likely to be smooth and responsive. It might also be slightly darker than the skin on the rest of a man's body, simply because it has access to more blood.

The entire length of the male organ is designed to be responsive to both touch and pressure, but there are some portions of this organ that are remarkably sensitive, including:
• The tip of the male organ
• The band of tissue that encircles the head, known as the corona
• The tissue that encircles the male organ, known as the sheath
• The tiny band of skin that connects the sheath to the shaft of the male organ, known as the frenulum
