I am 45 from Los Angeles. I am facing problem for over a month and I am too scared that I have done some permanent damage to my penis as a result of too much drinkng. It seems that the upper half of my penis is narrower than the lower half near the tip. Could this be due to constricted blood vessels and is there any way to make them return to normal shape? How about using viagra from http://www.canadadrugdepo.com.
