[|AI|]  Hello dear, The size of penis is genetically determined, and it does not increase after a certain limit. But one thing should be known that the size of penis does not determine the potency of an individual.It's only the outer 2 inches of vagina that is sensitive, which means that a penis of 2.5 inch and that of 6 inches will cause same amount of sensation and pleasure irrespective of their sizes. Semen volume as well as sperm production can be enhanced with the help of Nutritional supplements & vitamins like It E, It C, It B complex, Folic acid, Selenium, Zinc, L-Carnitine, etc. One more thing, kindly do not get influenced by any over the counter medication which claim to increase the size of penis or improve performance...it may be harmful. Wishing you a Good Health. Take care.
