There have been many studies on the average penis size and it is a frequently asked question among TeenHealthFX users and teens around the country. The average adult male penis size is about 6 inches with an erection. For a teenager whose body is still growing, the average erect penis size is between 2 - 5 inches. This is an average, some males will be larger and some males will be smaller, and this will depend on the person's stage of physical development.
Some men feel very upset and maybe even embarrassed because their penis is smaller. This is just one part of your body and personality. There are many other parts to you.
Teenagers commonly feel upset about their body and the changes it is going through. If you feel that something is wrong with you or are insecure about your body and the way it looks, seek some help and guidance from your doctor. Try not to be embarrassed discussing things like this with your doctor. Doctors are trained in dealing with sexuality related issues and will reassure you that everything is okay.
