The thing you pee out of. Its penis NOT panise.

No drug will make it grow. There are lots of drugs on sale that promise to do that - it's a fraud. In extreme cases, consult a physician - but perhaps consulting a psychologist is more adequate. What I mean is that from what I read, quite often, people who are worried about their size actually have a regular-sized penis. Quite possibly, there is nothing to worry about.
