1. Viagra actually has a strong delayed use effect. Many people do some experiments. They usually have sex for half an hour, but they can persist for an hour after taking Viagra.
2. Viagra, like other drugs, takes about 30-60 minutes to be absorbed in the gastrointestinal tract after oral administration, and the curative effect lasts for more than 4 hours. The best sexual life time is1-4 hours after taking the medicine, and many patients have a bad grasp of the time, which affects the curative effect. Therefore, after taking Viagra, there will be no effect of prolonging the sex time.
3. Research evidence shows that Viagra can effectively prolong the latent time of ejaculation, improve the hardness of erection, improve the endothelial function of penis blood vessels and further improve the quality of erection if it is taken intermittently or continuously for a long time. Generally, people with poor erectile function can try to improve their erections with Viagra, but people with good erections should never abuse it. First-time users had better consult a doctor first.
matters need attention
Although Viagra can prolong the time, it is best to eat less Viagra, do more physical exercise, eat a reasonable diet, and eat aphrodisiac foods such as dog meat and mutton properly.
