In fact, approximately one in five US men aged 18 to 65 years has ED. Erectile dysfunction is most common among younger men age 20 to 30 years, especially among young and unmarried males. This is a problem because many young males with ED have low motivation for intercourse because of low sexual desire. They also have the same problems obtaining and maintaining erection during sex, which means they are often unable to obtain or maintain an erection for intercourse. In such cases, doctors usually prescribe to buy generic Viagra online.
