Review hold more blood thus creating a much bigger penis. Your erections will be bigger, harder, and last longer, too. The good news is that with exercise, you will begin to see the benefits within a few short weeks. The gains will begin quickly, and they will be permanent.
My Personal Opinion: This is the final method I chose to do. And I'm glad I did. 2 months into using this method I wound up adding 2 inches to my size (plus many more improvements). Out of all the methods there are, this is the one I highly recommend the most. It's the most natural, the most safest, the most guaranteed, and the most effective. Just please understand that this is not some type of "miracle" method. You are going to have to put in work, dedication, and consistency to get amazing results.
