Comparing your penis to others is normal However, it’s not really fair to you because everyone is different, and teenagers in particular are even more diverse because they develop at different rates. So the locker room is not the best place to compare penis size. Also, the guy with the biggest flaccid penis may not have the biggest erection because a flaccid penis could grow a lot or a little when it becomes erect.

While there’s a lot of talk about penis size, the truth is that the average adult penis is between five and seven inches long when erect and a lot smaller when flaccid or limp. Some penises are wide and some are thin.

Since your penis is growing throughout puberty, which can happen anywhere between the ages of nine and 18, you won’t really know your adult size until you’ve stopped growing. And worrying about it won’t make it any bigger.

Remember that the size of your penis has nothing to do with what kind of person you are or what kind of sexual partner you’ll be.
