Twenty-five-year-old Xiao Zhang had just endured a harrowing night after taking Viagra. Dissatisfied with his sexual endurance lasting only about ten minutes, Xiao Zhang obtained a blue pill—commonly known as Viagra—from a friend.Without telling his wife, he took it. They went through their usual foreplay and passion, but after an hour, then two hours, Zhang remained "unrelentingly erect," leaving both of them anxious. They tried rinsing with cold water, applying ice packs, and fussed about all night until he finally calmed down.Viagra is not an aphrodisiac that stimulates sexual desire. People with normal sexual function may actually suffer harm from taking it! Clinically, young men often ask if they can get Viagra to enhance their sexual performance because their erections don't last long enough.Many profit-driven manufacturers market Viagra as a sexual enhancer. In reality, it primarily works by increasing penile blood flow while inhibiting the breakdown of enzymes in the brain that cause penile flaccidity, thereby sustaining erections.
Taking Viagra does not induce sexual desire nor produce extraordinary effects like prolonged erection duration or increased rigidity in healthy individuals.It only assists men with ED (erectile dysfunction) in achieving normal function after sexual arousal occurs. If healthy individuals take Viagra as an aphrodisiac, the first potential risk is inducing priapism (abnormally prolonged erection). Furthermore, long-term Viagra use by healthy men can lead to psychological dependence on the drug, causing a decrease in the secretion of enzymes that control penile flaccidity and resulting in permanent ED.
