Hey I’m 16 and I have started growing facial hair, body hair and have lots of pubic hair but my penis is only 4 inches erect about 3 flaccid, is this normal or should I talk to my doctor?

Thanks for your question. Congrats on wanting to make sure your body is healthy. There are lots of things that can affect penis length such as whether it’s flaccid or erect. It can sometimes be difficult to measure due to pubic hair and body fat distribution. It can also be hard to measure by yourself. You should talk to your health care provider about your concern.
