Well, I'm 47 years old, and I think that, at 4 cm, my willy might be somewhat below average length. Are there any stretches or exercises that I might do, in order to increase the length of my willy? I don't need to be a porn star, I just want to hit at a respectable 10 cm. Maybe there are some appliances I could use to aid in the lengthening of my willy? I heard that some people were capable of using duct tape, the hose of a vaccuum and a mouse trap in order to achieve these results. So my question is, how do I go about making my willy bigger?
