The question
Dear TeenHealthFX,
I would like to ask a rather personal question, is having a penis that is only 3 inches long when erect not normal at age 14?

The answer
TeenHealthFX understands your concerns and wants to assure you that having a 3-inch erect penis at age 14 is normal. In fact, [Healthline explains that when boys go through puberty not only do they grow taller but their penis and testicles also grow larger. This occurs throughout the entire puberty process. Puberty can take a few years to complete and for some, puberty in boys may not start until 14 or 15 years old and does not end until 18 to 20 years old. It may seem like you are behind, but boys always go through puberty later than girls.
We hope this helps!
