I am 18 years old (almost 19 actually) and I still look like a 14 year old. I have no facial hair, extremely little muscle mass, a very high voice, and my penis and testicles are the same size as they were when I was little. i do have some pubic hair and armpit hair, but those sprouted up years ago and have made no further development. I am also roughly 6'1" and weigh about 150 pounds. Please tell me what I need to do, my teenage life has been, for lack of a better term, a living hell.
