how to increase the thickness of the phallus

There are some surgical procedures which are reported to increase penis girth, but there also is some question about the actual success rate of these procedures. A more important question is why you feel this is necessary.  There are very, very few men who possess a penis that is NOT large enough to satisfy a partner; despite what society tells us, the size of a penis is far less important than the penis owner’s ability to use his penis. You would probably be better off concentrating on developing stamina (if that is a concern) and learning how to use your penis to drive a lover wild than with trying to increase its girth.  Also, keep your penis in good health through the use of a high quality penis nutrient formula (health professionals recommend Man1 Man Oil).  A formula with a range of vitamins, such as A, B5 and D, is best.  Good luck.
