You mean "how can I make my penis bigger?" or "how can I make my penis big?"
There are four options... contrary to what everybody believes:
1. There are manual penis enlargement exercises
2. Using a hanging device
3. Using a traction device
4. Or penile enlargement surgery
I've safely gained an extra inch and a half in erect length, quite a bit of girth, and a much larger flaccid penis with the penis enlargement exercises. That's my favorite option by far.
I wrote about the increase in flaccid size, and a little more about the exercises, here:
"A Question regarding Exercises to Increase the Size of your Flaccid Penis"
I know it's hard to believe... but trust me man... no b.s.
