You are fine, don't worry. Adult average size is 5-1/2, at least that's what I read, so you likely will be well beyond this by adulthood. It isn't the size that is the big deal but how it is used. Also, there are a lot of characters who joke about size and tease, which you likely will read so dismiss them.
As much as I'd like to tell you something positive, I really have to make note of the incorrect information in this thread. I'll repeat what I posted to another person who asked a similar question:
The average size supposedly a bit over 6", which is about 15.25cm. Also, penises only grow from about the ages of 9 to 15 or so, so you still have the potential to grow. I'm no chick, but I'd say for most girls, anywhere between 13cm and 18cm is the target range. The "G Spot" is supposed to be only around 3-3.5" (7-9cm) on the top wall, so as long as you can reach that in most positions, you're all good. ;)
So, to break it down... you still have the potential to grow, but don't get your hope up on it getting to 6 inches. However, the fact is, it really doesn't need to. For every woman that loves a nice long dick, there is one that hates it and prefers something smaller. There is a man for every woman and a woman for ever man so don't let the length get you down. However, you should measure the girth, which women have statistically said is more important. Get a soft measuring tape and wrap it around the fattest part of your erect penis. This will measure the girth. The average girth is supposed to be 4.5"-5.25". If you're in that area, you're more than fine.
you can also make it look bigger by shaving, as pubes hide 2cm of it. And there a plenty of massive guys with small dicks, unfortuantely i know because in my gym, the changerooms always have naked guys just standing there. if i had a dick that small, id hide it. you sound normal, kid
I would not worry. you have plenty of time for it grow and if it doesn't get that big so what you and any girlfriend will have lots of fun with it. Ignore those toerags above who are saying its small chances are they have really small dicks anyway! If you want to get it bigger there are lots of safe way to do it including a pump. Wank yourself silly and have fun
