Hello-
eat a healthy, well-balanced diet. Consumption of fatty foods leads to the production of plaque that clogs arteries and blocks the flow of blood to the heart. This plaque can also block the arteries leading to the genitals, interfering with the ability to achieve an erection.
Include pumpkin seeds, bee pollen or royal jelly in your diet.
Avoid alcohol, especially before sexual encounters.
Be sure to maintain a regular exercise regiment.
