I have been cooking Chinese at home every day. I noticed that the Chinese Spicy Bean Sauce is another secret to longevity and frequency of erection in my anatomy. With generic v, I take 4-20 mg pills on an empty stomach one hour before action. Beets, watermelon, pumpkin seeds are other alternatives.
With Chinese Spicy Bean Sauce, I can maintain the endurance for as long as it wants to whether my stomach is full, 1/2 empty and empty. Works for me every time and can do 2 loads within an hour. Can do action 3 times on the same day. TOFFT and share the outcome with us.
YAMV (Your anatomy may vary). Cost $4 a 1/2 pint jar and use one teaspoon every time I cook something.
