Vasa Max I am going to have any kinds of marks on my penis from doing these routines, or have any signs of in fact doing these exercises that women would be able to notice? Any increase in the size of veins or anything?These are some answers to common penis enlargement questions. The facts point to natural penile exercise programs as being the best way to increase size. Maybe it is not the sexiest method to try, and it certainly is not the most heavily advertised, but with all the clinical proof that it works, who cares? Just choose a good program and get started!
