I've been pumping for a year. I started just to maintain my size. I have ED and I don't get night erections. After a year of pumping I'm able to cut down on the dosage of viagra and I have actually gained size. I'm 60 years old so this result surprises me. Has anyone else experienced this? I really didn't believe that you could get permanent growth. Maybe if I stop it will go away but why should I stop?
