A: Most likely.

While there's a lot of talk about penis size, the truth is that the average adult penis is between 5 and 7 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 9 and 18, you won't really know your adult size until you've stopped growing.

It's best to quit worrying about it. The size of your penis has very little to do with what kind of person you are or what kind of lover you'll be.

Some people like guys with large penises, but many would rather have guys with average size penises. So, when someone says "size matters," that doesn't have to mean that bigger is always better.

Courage to talk to your partner about what feels good is more important than size. A guy with a large penis who has no idea how to please a partner is going to be a lesser lover than someone with a smaller penis who takes the time to find out what his partner really likes.
