Can anyone answer my question about enlargement?

I have heard sizegenetics ( stretcher) really does work. It makes sense right? Everyone says stretching exercises work well why not use something that stretches it for you? So if I used this sizegenetics thing in combination with male enhancement pills (increasing the blood flow) could I see noticable gains? I'm only 7" long 5" girth but I want more. According to statistics it would appear I am above average but it does not look that way to me.
