Luke, it's not as short as you think; when we see someone elses endowment, it always looks larger because we are seeing it from a different angle/perspective than seeing our own. And when you meet the right person, it doesn't matter at all.
Just get out there ad enjoy yourself. Not really anything you can do to increase size, short of some kind of surgical procedure maybe. Just keep the hair trimmed short or shaved, so the little fellow has nowhere to hide. Otherwise it might get completely hidden in the bush.
