Question: what does viagra do to your penis

Answer:Viagra is an oral medicine to treat impotence, i.e. the inability to either obtain or maintain an erection that is sufficiently hard for penetration. The active ingredient sildenafil citrate is a vasodilator which means it improves blood flow to the penis. This enables a man suffering from erection problems to gain and/or maintain an erection when aroused. Please note that Viagra restore erectile function in men who are experiencing a loss thereof due to psychological or physical causes.
