Penis enlargement - the best in this category, below.

When a man is sexually excited, the penis rapidly fills with more blood than usual. The penis then expands and hardens. This is called an erection. After the man is done having sex, this extra blood flows out of the penis back into the body. The erection goes away. If an erection lasts for a long time (more than 6 hours), it can permanently damage your penis. You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours.

Some conditions and medicines interfere with this natural erection process. The penis cannot fill with enough blood. The man cannot have an erection. This is called erectile dysfunction if it becomes a frequent problem.

During sex, your heart works harder. Therefore sexual activity may not be advisable for people who have heart problems. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem.

Here’s what usually happens when a man is sexually excited:

1. The arteries in the penis relax and widen (this allows more blood to flow into the penis).

2. These arteries then expand and harden.

3. The veins that normally carry blood away from the penis get compressed (this restricts the blood flow out of the penis).

4. More blood begins flowing in and less flows out, making the penis larger; this causes an erection.

Your Penis
Given the amount of attention to this important body part, it is strange that there is so much myth, mystery and misinformation about the penis. First off, there are no bones or muscles in the penis. In fact, the penis is made up primarily of spongy tissue, which becomes engorged with blood during erection. Two or three inches of the penis are rooted inside the body in the pubococcygeus muscle (PC muscle) and it is possible to strengthen this muscle for stronger erections, stronger orgasms and better ejaculatory control.

Your Testicles
Because normal body temperature is too hot for sperm production, your testicles hang down, away from the body. As you prepare to ejaculate, the testicles are pulled toward the body. Sperm move through the vas deferens, a firm tube that extendes from your testicles to the prostate gland, where they mix with secretions to form your ejaculate. The sperm are actually only a small part of the ejaculate.

Your Prostate
The prostate is a gland that lies at the center of your pelvis and is highly sensitive to sexual stimulation. Some authors have even called it the male G-spot. During erotic stumlation, the prostate becomes increasingly aroused. The closer you are to orgasm, the more sensitive the prostate is. About 1/3 of your ejaculate comes from the prostate, so keeping your prostate healthy is very important (though examinations can be unpleasant). The prostate can be stimulated externally or through the anus.

Your Perineum
The perenium is the area between the base of the testicles and the anus. This area can be very sensitive to sexual stimulation, especially during orgasm.

Your Pubococcygeus (PC) Muscle
The PC muscle is actually a group of muscles that run from your pubic bone in front to your tailbone in the back. You use the PC muscle every time you stop the flow of urine from your bladder. It is also the muscle that contracts when you ejaculate, moving the semen up through the penis and out of the body.

Your Anus
Due partly to it's proximity to the prostate gland and partly to its own high concentration of sensitive nerve endings, the anus is a highly erogenous zone for many men (both gay and straight). Extra care must be taken while sexually exploring this area, as it is rich with bacteria.
