17 and worried

You can’t tell anything about your size until its been a year since you stopped growing generally. It could be that you have finished growing by the age of 17 and that this is the final size of your penis. So what?
It is actually not in size but in the things he could do, so instead of wining, I would sit down and start learning because there is nothing you can do about your size. There are no pills that enhance the length and the surgery can only improve the size in 0.5-1 inch.
There are some penis lengthening exercises but they are not really safe and it is a question whether they would work at all.
If you are worried about not being able to satisfy the girl, I will tell you once again-you better start learning what women like and what feels good and how you can make her happy sexually instead of searching for the non-existent way to enhance your penile size. I am sorry but it is just the way it is.

men don't usually stop growing till at least 21 so give it some time. and what the gentleman said above is right on! i'm female and size doesn't matter to be as long as the sex is good. i don't know why men get this idea that they need porno-size penis'.. as long as you are into sex and try to make the woman feel good your doing all you can. size doesn't determine how much a woman likes it... stop worrying and let nature take its course..

it's not the size that counts! it's what you do with it that matters! ;-)
