Viagra online is one of drugs that are manufactured by the company known as Pfizer. This drug was the first to be approved by the FDA for treating male impotency or erectile dysfunction. Viagra online contains a very active ingredient known as sildenafile citrate that works by relaxing the body muscles including the penile muscles. When the muscles are relaxed, more blood is forced to flow into the penis and other parts of the body as well. Viagra online assists by increasing the manвЂ™s ability to attain and to sustain an erection that is required for sexual intercourse when he is sexually stimulated.
Most of the individuals who use Viagra online as a solution for their erectile dysfunction problem report high stamina, faster recharge and amplified sex drive. Note that Viagra online can only work when you are sexually stimulated, it only assists you to be sexually satisfied though you must know that it cannot prevent you from getting sexually transmitted diseases. Many people ignore taking Viagra online because they feel that it can show its effects at any time. This is false because this drug can only show its effects on an individual when he is sexually aroused.
When you are sexually stimulated or aroused, your penile arteries will relax and increase in size which will allow more blood to flow into it. Generally, when the penile arteries continue to widen they become harder and compress the veins which carries blood from the penis hence they restrict the blood that flows out from the penis. At this point more blood will be flowing in and less blood will be flowing out thus the penis will enlarge and erect. Viagra online is not a hormone like many people thought so it only performs its work when you are sexually stimulated.
