Though there are several treatments available for erectile dysfunction, men have always tried to prefer natural ones over others. There have been many studies and experiments to know if some natural foods, herbs, or supplements can help a man achieve and maintain an erection.
On the other hand, ED medicines such as Viagra, Cialis, Levitra, and Stendra help by improving the erection for a specific period of time, usually a couple of hours for good sex. No matter however you take higher dosages such as Cialis 60 mg which can last up to 36 hours, but with time, its effectiveness will keep dropping with hours.
