It can be very frustrating if you feel “different” then your friends however, everyone develops at different stages. Some guys go through puberty on the early side and others develop on the older side, and then some develop sometime in the middle, which is considered the “average” time. Regardless, it takes about 4-6 years for the penis to reach its final size. On average, young men will experience rapid growth of their penis and testicles between the ages of 12-16 (but some young men may develop earlier or later).  There are no products, herbs, pills, or exercises that will permanently change the size of your penis.  Since you are only 14, your penis is likely to get larger in the next couple of years. Anytime you are feeling “down” and it lasts longer than a couple of weeks, you should talk to your primary care provider.
