Penis Size: average fully grown is 5.5" by most studies. At 16 you could be just starting, be midway, or be finishing puberty when penis grows, beard develops with other body hair, etc. Males can continue to grow until 25 or so. Relax, my friend since you will have what you will have - enjoy it and use it SAFELY and it will serve you well whatever size it is!
