3. With this enzyme knocked out, my soft-muscled penis tissue relaxes, opening gates to flood my organ with blood.
3. As I become sexually stimulated, my brain sends pleasurable signals to penis cells where nitric oxide builds up.
4. The nitric oxide relaxes the penis arteries further, allowing even more blood to flow. It overwhelms the emptying veins.
5. Ta-dah! I have a strong erection.
Because the PDE5 enzyme is found only in soft muscle tissue, Viagra works only on the penis muscle. I have noticed some side effects which are normal. With Viagra in my bloodstream, all white light appears lightly tinted a slight blue hue. The tint does not impair vision in any way—sight is not blurred or foggy or out of focus. In fact, sometimes it is outright enjoyable seeing the world in this rather unique light. For me, the erection time period lasts from four to six hours but only when I’m stimulated. The product warns that a massive erection lasting longer than four hours should take one to an emergency room.
To sum up, if you find yourself frustrated by an inability to satisfy your sex partner — or yourself for that matter — due to erectile dysfunction, my best advice would be to see your doctor. But do yourself a life-saving favor. “The loss of erections is a harbinger of subsequent cardiovascular disease and demands a comprehensive cardiovascular workup.” (SeekWellness.com)
Do not be satisfied to accept a prescription for Viagra unless your talk to your physician about having your body, particularly your heart and the blood vessels (carotids) leading to and from your brain, checked for blockage which could lead to major problems—a stoke or a heart attack. I am lucky to be alive physically. Sexually, I feel whole again with a satisfied masculine ego—and thank God for Science.
