Penis size for 13 years old

Is a 4.5 penis small for a 13 yr old?

Tibor's reply:

For 13 years old it's ok. Check the pages on this site about Average Teen Penis Size by age.

Follow the 'Puberty Chart' for boys so you know where you are at any given point (compare the signs).

This all will give you a pretty good picture.
Don't forget; for everyone it happens at different time and rate.

You don't need to worry unless you notice an extreme difference.

What is important, you are just beginning your puberty.
You will experience significant growth and changes during your puberty.

It will take some time, it doesn't happen overnight.
