Wow...that's a new one on me! I never really considered eating a specific type of food or a specific type of diet that makes your penis grow longer or have more potent sperm. I know in some countries that the rhinoceros' horn was highly prized for its sexual potential and making a man more potent and strong when the horn was ground up into a powder. the other thing I have also heard from some men,but it has never been proven, is that oysters, when eaten raw, provides a certain nutrient that keeps a males sexual vigor going and makes him more potent in the sperm department. Those are about the only things i have heard told to me.
