If you want fast results in length, then you should check out the hanging forum. That is the best bet for length, but there is no guarantee that you will be a good gainer.
I got about an inch in a month, but that is VERY unusual, and I did some stupid stuff when I first started.
Just be sure to take it easy, and make it comfortable. There is no quick road to penile bliss yet. Though by sticking with a routine you will eventually see gains.
The thing I tell myself is “I wish I would have started a year ago, how will I feel in a year if I keep up my routine.” there will be no regrets, because my dick will be well above average.
This is a long and slow road, but the rewards are almost endless (at least for me).
