Penile Exercises and methods?

[You Dont Know Me]

Hey guys and gals. I've been reading up on something called jelqing, which is a natural penis exercise that is supposed to make your penis bigger. Does it really work, is it safe for a teenager to do it. will there be any chance of something going wrong and if so what are those. If it does work how, how much larger will my penis be. If this doesn't work what other exercises can i do to make my penis bigger. Even if there isn't what other natural exercises are there? Thanks

The person who answers all my questions and gives me the most info gets best answer.
