Many people have asked me whether Viagra and Fildena 150 work well together or not. The truth is that they do but it takes some practice to get the right combination going. Fildena is usually used when people are having problems either in getting an erection, maintaining an erection, or getting an erection and maintaining it throughout the sexual act. Some other conditions that Fildena can help with include premature ejaculation, PCOS andropause. Fildena is known to increase blood flow to the genital organs. It also increases blood flow to the nervous system and brain. This helps improve overall blood circulation. In addition to this, Fildena allows more blood to reach the penis when you have an erection. This helps create a firm erection and maintain it throughout the sexual act.
