As a man,
Avoid pornography and eat more of these for better erections, stamina, testosterone, and sexual health:
Pomegranates, watermelon, honey, bitter kola, walnuts, red meat, salmon, garlic, cloves, ginger, oysters, ginseng, dates, avocado, maca root, eggs, banana, coconut water, beetroots, and cinnamon.
Improvements come naturally with consistency.
