I'm 18 and my penis is about 5.5 inches. Yea I know I'm below average so I would like to increase my size. I've been reading online and it looks the Penis Advantage program works the best but I don't want to buy it. So I was wondering if the exercises they use are the same as others around the net (jolqing, starting and stopping, etc) or are they something that works better? All answers are appreciated
