You could invest them in an extender. Why not surgery, creams or pills? Because they don't work. Ok, maybe the surgery will, but you'll feel like having a fake penis. Would you feel better if injecting oil into your biceps or after training them? The same is with the penis. When you stretch the muscles, they tend to get bigger as they break and then recover. Yes, it takes a lot of time for the results to show, but believe me, they do. After reading about extenders on
